Personally I still think a frequent EMU fast service Padd-Slough-Reading(-Didcot-Oxford) should operate, with local passengers banned from the fast services entirely, certainly in the peak, following the WCML model. Paths could be found by portion working some fasts as 2x5 splitting along the way.

This would mean a significant reduction in intercity services into Paddington (compared to the present plan) since there wouldn't be the demand. And your services would either have a significant number of empty seats east of Reading or overcrowding west of Reading.

The option planned of running extra intercity and Thames Valley fast services and having some intercity services run non-stop through Reading seems fundamentally superior to your suggestion.

The overhead wires on the other hand are a new and colossal potential for failure. I know this new kit is meant to be as tough as the proverbial outbuilding and even if it falls down on one line, you are apparently able to keep running on the next track(?) but I will believe it when I see it. Whether the trains are doing 3,000 miles or 30,000 will probably be a minor detail to what could go wrong there.

The reliability requirements for the Series 1 OLE are really rather onerous, the accelerated stress and ageing testing being undertaken by Furrer+Frey (such as the work at the University of Sheffield) and elsewhere is promising, as is the reliability we're seeing on the GEML, where the GE precursor to Series 1 is doing really good work.

There are parts of Series 1 in service elsewhere, and it's a known quantity which is why Series 1 is designed as it is - it's already making use of the best designs out there currently in service.

There's little question dewirements will be disruptive, but they're not going to be anything like as disruptive as the dewirements we see on the ECML - Series 1 OLE plus IEP with its single diesel power pack is going to make the very best out of a bad lot during a dewirement.

Series 1 is also incredibly easy to repair and get back up and running - large dewirements will be repairable in very short access windows.

It's also silly to think the OLE is going to be the source of most disruption so why bother with exceptional train reliability. We should be (and some of us are) pushing for a railway where as few services as possible are cancelled due to failed stock or lack of stock. NR, TOCs and service providers can work round a dewirement to get pax to their destination, they can't work round absent stock.

There seems to be a revisionist history of IEP being written if your recent posts are to be believed. We should not forget it has taken over 10 years to get to where we are now, through a specification written by DfT that attempted to re-write the laws of physics, to an exceptionally expensive price-tag. And if reports are to be believed, which given who has written them I suspect they are correct, the interiors of the IEPs will be worse than what we have now.

As for Bombardier, they have upped their game: the Class 387 build quality has been very good (shame about the customer specified bits...), though perhaps not up to the standard of Siemens yet.

We've discussed HST2 and the numerous changes that have taken place between the HST replacement project being launched and where we've got to today.

There's no revisionist history, the project has changed, evolved and what's happening with IEP will undoubtedly continue to change and evolve before they enter service, and during their time in service.

DfT have managed to procure a really good product, as I've said, I think it's down mainly to Hitachi rather than DfT. They thought we would be using HST clones powered by bionic duckweed, I think some contributors here think that's exactly what we should be doing.

The biggest criticism is the funding model for IEP - it's far from ideal, AT300 on the other hand has proven itself to be affordable and desirable with conventional ROSCO funded orders for three franchises.

The $1 million question which we will never be able to answer is whether a manufacturer would develop something as complex and difficult to place into service as IEP/AT300 without what could effectively be thought of as government grant funding ?

There wasn't exactly a queue of manufacturers with 125mph electric units and bi-mode stock wanting us to buy their wares instead of IEP. Bombardier had scrapped the jigs for the Voyagers, Alstom were no longer speaking to Bombardier for electric traction and their diesel Coradia family didn't fit being converted into a bi-mode design, being as it was a diesel-hydraulic design, and nobody had 26 metre stock developed if that was needed.

What did we have to choose from - more Alstom Pendolinos and some locomotives to drag them from wherever the wires reached - and maybe if you're being generous, more Hitachi Class 395 units. We've been promised all sorts of other units over the years - 125mph commuter units, new electric locomotives and so on, but they've all fizzled out with commercial considerations and costs being impossible to square.

There's also plenty of reports from the press run into Paddington which commended the comfort, ride, noise and general ambience of IEP. I'd take Roger's comments with a pinch of salt. There's plenty of people away from the enthusiast community who don't particularly enjoy Mark 3 stock, who can take it or leave it, who find seating rather than anything else more important.

I am referring principally to Westbury and Exeter as per topic but Bristol is equally true.

I am sure it is great for passengers, after all they are not paying. As I illustrated for WC it is economic madness and will cost the taxpayer a fortune. The extra demand does not come close to matching the additional costs.

The NR credit card has been revoked and with their debt nearing £50bn, pretty soon reality is going to catch up with the industry.

The solution to empty Pendolinos at 3tph on WC is not to double the number of cabs in the fleet and shorten the trains. The solution to 3hr London Plymouth is not to skip a couple of stations and run one train per 2hr from London to Exeter to cover Castle Cary and Tiverton. 5 cars is not being used to vary off peak train lengths, it is being used to run loss making trains that should not be running at all.

That's one powerful crystal ball you've got there - not one of these additional GWR services has turned a wheel yet but you know they will lose money...

I repeat, what massive ramp-up in services? The semi-fasts will run every couple of hours - that's all. They will provide some consistency in service at the stations between Reading and Taunton, where the key characteristic of the current provision is inconsistency, with some stops provided by the current erratic semi-fast service, with others inserted into Plymouth and Cornwall services, often with large gaps in between.

But I take it that's just fine and dandy in your view and the status quo is all that the passengers will require/deserve. Passengers who most certainly will be paying - through the money taken in taxes that the government puts into the railway and through the fares they pay, fares which now cover about 70% of the network's operating costs, far more than they used to.

What does the Network Rail credit card - otherwise known as part of the national debt, which is what it has always been, whatever clever accountancy and company structure ruses the Government has tried to come up with over the years to pretend otherwise - have to do with a project to deliver new trains?

It was successful in that the core idea of Princess - half hourly services from Birmingham to Newcastle, Reading, Manchester and Bristol are still there today, and in that it increased passenger numbers, yes. There is still insufficient capacity on many XC services, hence my suggesting it wasn't a failure, rather a victim of its own success.

That's not much of a bar for success, when we are still stuck with the same inadequate trains, now partly bailed out, irony of ironies, by a handful of the HSTs that Virgin got rid of a few years earlier, as they were old thinking, from boring old BR - which, for all its faults, never ordered a four-coach train with three ginormous accessible toilets that stink. And probably wouldn't have removed XC services from the second-largest city in the North West or the capital of Wales - I exclude the Cardiff-Nottingham service, as that was not part of XC in the past and doesn't have intercity rolling stock.

Just to be clear, you are saying that it isn't possible to seat over 326 passengers at places like Cheltenham and Worcester without having passengers standing at the London end or going all the way up to a 9-car train?

Just to be clear, do you have any idea of what loadings at Cheltenham and Worcester - or between those places and London - are like? Out in West Wales, I somehow doubt it. Whereas the people at GWR responsible for planning future services do actually have access to information about loadings on their trains and stuff like future housing developments along their routes.

I've told you more times than I care to remember, over several years, that peak HSTs formed of high-density stock, which seat something north of 550 people, are often full when they arrive at Oxford from the west, as are some heading the other way, so I'm afraid a six or seven-coach IEP formation just wouldn't cut it, which is why GWR will use nine-car sets at those times of the day.

If the class 387s etc. aren't going to keep enough short-distance travelers off the IEPs and every IEP out of London needs over 600 seats, then in my opinion an all 9-car fleet it has to be. This would of course result in lots of empty seats on quieter parts of the network, but that would be the case even with 5-car sets available as any demand of 327-567 passengers cannot be accomadated on a single 5-car set and would have to be a 9-car or 2x5-car formation.

If you can keep enough short-distance passengers off the Intercity services out of PAD to allow a number of shorter Intercity services (such as the 180s operated today), then it makes more sense to have a mix of lengths and diagram appropriate length trains to each service.

People have been telling you for years that operating five-car sets makes sense, when diagrammed appropriately. Has the penny finally dropped? Probably not, given what you said immediately above. Having a random series of train lengths does not make sense, with the rationale for using nine-car or 2x5 formations, equalling about 630 seats in both cases, explained above by others.

I must admit that I overlooked that limited enhancement between Cardiff and London, but Swansea already has 2tph to London in the (London) peaks, so only two Welsh stations (Cardiff and Newport) are actually certain to see a frequency enhancement.

No surprise you won't take anything at face value. GWR did not say Cardiff-London. They deliberately chose to say South Wales. Let's see what happens...

You are right, it doesn't mean they need 8 coaches, but it doesn't mean they don't either. SEWTA thinks they need 8 coaches, all-day on weekends and at peak times on weekdays.

You can say it, SEWTA can say it, doesn't mean an eight-coach train, or nine, is what's actually appropriate all the time - I could demand eight-coach HSTs on every train on the Cotswold Line. But it would be daft.

Personally I still think a frequent EMU fast service Padd-Slough-Reading(-Didcot-Oxford) should operate, with local passengers banned from the fast services entirely, certainly in the peak, following the WCML model. Paths could be found by portion working some fasts as 2x5 splitting along the way.

Please can we not turn this into yet another 'what should be done about Reading commuters' thread. Especially when someone pitches in right from the off with talk of banning people from doing stuff, even though we have yet to see what the GW and Crossrail timetables between Reading and London will actually look like come 2019, never mind the loadings on the various services that will be on offer in the Thames Valley, or ticketing arrangements.

I really believe the rot set in, from the old Bristol TM/Bath/Paddington nonstop service when privatisation split things up between the long distance and the Thames Valley operations, whereupon the long distance operator decided they were going to grab additional revenue for themselves from the regional operator by stopping much more at Reading, Didcot, even Slough. I agree it has become a grand outer-suburban service, but what is poor is that it is provided by long distance trains.

BR had split things up between the long distance and Thames Valley operations when sectorisation was introduced. Reading is now the busiest interchange station in the country after Birmingham New Street and the town is as much a destination for inbound commuting - from every direction, including the east - as it is a source of commuters to London. That's why lots more trains stop there. The revenue was not grabbed off another operator, there was plenty to go around. Didcot's population in the 1991 census was 16,000. It's now 30,000 and rising, so no wonder more trains stop there. The world is changing, the railways do too.

Having 2 x 5 car sets seems to me an ideal approach, but I believe the privatisation financial model doesn't allow for that and we will end up with the 180 saga all over again (remember when those first came along, on Paddington to Bristol) and just have 5 car sets on the whole run because whoever the franchise operator is gets charged by the car by the mile.

Th 180s were acquired by FGW to test the water for an expansion of Bristol and Cardiff services and, despite the iffy reliability, quickly proved that there was a good market there. So much so that by 2004, FGW was acquiring more HSTs to replace them on these jobs, allowing the 180s to be moved to the Cotswold Line.

One difficulty with long distance travellers from Paddington being unable to get seats is the short times now allowed for trains to be opened before departure. Used to be that services to the West etc might be open 30 minutes before leaving, those for Penzance (and Taunton) could take their seats while those for Reading had earlier services, and it was only in the last 10 minutes or so that they "filled in". Not the case any more. Sub-10 minute train openings seem to be becoming more prevalent each year, even on services which have been sat there doing nothing for a long period.

There used to be rather fewer trains operating out of Paddington, so platform occupancy wasn't the issue it is now. Trains 'sat there doing nothing' are being cleaned, catering stores loaded, seat reservations put out...

a much increased Crossrail stopping service that will have their eyes on close headways and exclusive use of the Reliefs

Crossrail will not have exclusive use of the reliefs. GWR will still have two relief line paths per hour in both directions after Crossrail services start.

Hello Mr Serpell. I thought you had died in 2008.

Are you 100% sure about that? My recollection (as someone who commuted from the Cotswolds to Wokingham for a long time) is that GWT and (IC-only) FGW continued to omit the Reading stops on their Cotswold services. It was only when First got their hands on the Thames franchise that Reading stops were added - and very welcome they are too.

Too many hours waiting on Platform 4 at Reading as a far-from-full HST sailed past on its way to the Cotswolds (17.12 ex Paddington), while I waited for the rancid, overcrowded, long-wait-at-Didcot Turbo that followed it (17.18 ex Paddington). :(

I don't know. But if they were all that quiet wouldn't they would have even fewer IC125 services than they do currently?

Out in West Wales, I somehow doubt it.
I've never been on the 07:30 Carmarthen to Paddington service, but from what I've seen of the other workings I would agree that a 2+8 IC125 isn't really needed west of Swansea. But I believe a shorter train would probably be inadquate further east, therefore I am in two minds about whether the through London services west of Swansea should continue, but if they don't I would want assurances that the Wales & Borders franchise would provide enhanced services between Carmarthen/Milford/Pembroke and Cardiff/Swansea to make up for the loss of through trains.

I've told you more times than I care to remember, over several years, that peak HSTs formed of high-density stock, which seat something north of 550 people, are often full when they arrive at Oxford from the west, as are some heading the other way, so I'm afraid a six or seven-coach IEP formation just wouldn't cut it, which is why GWR will use nine-car sets at those times of the day.
Did I ever suggest the whole GWML IC fleet should be 6 or 7 coaches? I don't think so, as far as I can recall I've always said that the GWML IC fleet should be comprised of either:
  • 8/9-car trains only or
  • some 8/9-car sets and some shorter ones
Which of these options I would select would depend on the maximum loading at any point of each diagram, as I admitted above, I don't know.

People have been telling you for years that operating five-car sets makes sense, when diagrammed appropriately. Has the penny finally dropped?
Have I ever denied that? If the 180s aren't full at any point of their diagrams, then a 5-car IEP should be fine on those diagrams. I just don't think FirstGWR will find anywhere near 32 such diagrams, they can put the 5-car IEPs on 7-days a week. Yes, some can be 10-car in the peaks and in theroy be uncoupled at Paddington to run shorter services off-peak, but are there enough services out of Paddington that a 5-car set would be sufficient on?

Having a random series of train lengths does not make sense, with the rationale for using nine-car or 2x5 formations, equalling about 630 seats in both cases, explained above by others.
Yes, you need a full length train in and out of London in the peaks, that's obvious. But equally,
I could demand eight-coach HSTs on every train on the Cotswold Line. But it would be daft.
Just because there are less passengers off-peak, it doesn't mean the number passengers drops from over 600 in the peak to 300 off-peak. Train loadings are going to vary widely, some services might have 200 on board at most* but others might have 500 or more, or anything in between.

If you want to match train-length closely to demand on each service, then you need "a random series of train lengths", otherwise you are always going to end up with either passengers not getting a seat or trains much longer than necessary. On regional and suburban services, you can do it by having short (2-car and 3-car) units that you can run in multiple to make up any length of train from 2 coaches upwards, but with 125mph stock the cabs take up too much space to have lots of short units, so the only way you can meet a demand between 350 and 500 passengers without running a 9-car unit is to have some units with 6-8 coaches.

* in this case, if you have a whole diagram of services like this with no busy workings, you can use a 5-car

You can say it, SEWTA can say it, doesn't mean an eight-coach train, or nine, is what's actually appropriate all the time
They're more likely to know how busy the services are than me, and note that they didn't say every train had to be 8 coaches on weekdays, only in the peaks (but they did say every train should be load 8 at weekends).

I think many of us here are able to distinguish between trains being serviced in the manner you describe, and "sat doing nothing". A typical one not long ago at Paddington had sat for 50 minutes, was opened just 10 minutes before departure, and THEN had the attendant coming through trying to insert reservation cards after half the seats had been taken.

Crossrail will not have exclusive use of the reliefs. GWR will still have two relief line paths per hour in both directions after Crossrail services start.
Another issue is, after all our experience of changes being made annually, often substantial, believing that however forward plans will be fixed for all time. And I would think it most likely that these residual GW stopping services on the Reliefs, which will instantly become known as the "Crossrail service", will be the first to go. It's just silly to have half Crossrail westbound terminating at Paddington, meanwhile upstairs a separate service stopping at all the same forward stations is starting. Passengers arriving at Paddington will automatically head for the subsurface Crossrail platforms first.

But you are right, Crossrail will not have exclusive use of the Reliefs. A Class 66 dragging Mendip stone into Acton Yard is going to do no good at all to the precise presentation of the following Crossrail services into the Core, as is only too apparent on the North London Line nowadays where a ramped-up Metro-frequency service is regularly delayed by heavy freight on the same tracks.

Is there any commercial reason for runnning aggregate trains during the daytime on that route?

We're out and about at night sticking bits of metal up at the side of the track, when electrification is wrapped up, more overnight paths will be available.

There's also a fair amount of infrastructure going in to allow the stone trains to get out of the way and remove conflicting movements, such as the dive under at Acton so they don't get in the way during daytime movements.

If you look at the scheme and ignore some of the more fantastical claims made on fora such as these, you would get the impression people who knew what they were doing were responsible for designing the new trains, electrification and track infrastructure for the GWML Route Modernisation program.

The $1 million question which we will never be able to answer is whether a manufacturer would develop something as complex and difficult to place into service as IEP/AT300 without what could effectively be thought of as government grant funding ?


This is a very important point, often lost in the noise about funding, design, hauled vs multiple etc...

We needed a new HST for the future, that could be deployed practically anywhere on the network. It become increasingly more important that these units where versatile post the decision to go ahead wi HS2, which will remap rail franchises north of the M4. We needed something that the industry wasn't working on, we needed something that would remain in production for 20+ years. That something emerged from the initial huge investment debt incurred by the IEP funding model.

That's only one of the conflicts. And any trip down the line shows that it's not just isolated movements, there is a lot of heavy daytime freight on this line (greatest tonnage per year into London? quite likely). Even pulling one into a loop, to a stand, and have it come out again, is likely to hold up things behind such that it's probably just as effective to let it continue running.

To be precise the Acton diveunder is not for stone trains, it is for empty wagon trains returning to the quarry. As I understand it the gradients in the new diveunder would preclude loaded stone trains from using it.

We all recall the Southall accident and one of the issues leading up to it was the difficulty signallers had, even then, in getting these trains across the layout among the intense services on this route - which is why an empty freight was given priority over a high speed passenger.

Why do you think these will be known as 'the Crossrail service'? And even if it does, does it matter?

You are aware that the two Relief line paths for the GWR stopping services are projected past Reading to form the local service to Didcot and Oxford? This means passengers from and to the main intermediate points between London and Reading (Ealing Broadway, Slough, Maidenhead and so on) still have a through service. This means that there is no enforced change at Reading. These trains will, for the foreseeable future, remain as they fulfil a demonstrable need.

Passengers arriving at Paddington will automatically head for the subsurface Crossrail platforms first.

I don't understand. Do you mean passengers arriving at Paddington on main line trains or people arriving at Paddington wanting to travel west?

If the latter, then allow that (many, most?) people have some intelligence and can work out that the train for, say, Pangbourne does not start from the low level platforms or that the change from the Hammersmith and City line to a Slough train departing from the main train shed - and making fewer stops - might be easier and quicker than a hike to Eastbourne Terrace.

The Acton diveunder is not for freight trains at all. It permits passenger trains on the Up Relief - or actually a loop off the Up Relief - to dive under the connection from the Reliefs to Action Yard and so avoid conflicts.

These days freights tend to be confined to the Relief lines because the stone trains to and from the Berks and Hants now have a grade separated junction at Reading. The issues raised by Southall have, to a large part, now been solved.

The next steps are grade separation at Southcote Junction to remove conflicts with the practically hourly container trains to and from Southampton and at Didcot to keep the down Oxford trains from conflicting with the intensified up Bristol and Gloucester trains.

Although these proposed GW "all stations" services may continue beyond Reading, the time differential between all stations and non stop to Reading is sufficient that I'm sure the bulk of Pangbourne's passengers will look to take an express and change at Reading.

And I do believe the service at the likes of Southall or Langley will become universally known as the "Crossrail" service, as they will provide the bulk of the service.

Ah, then I've misread the contractor's (Volker) documentation.

Just to be clear, you are saying that it isn't possible to seat over 326 passengers at places like Cheltenham and Worcester without having passengers standing at the London end or going all the way up to a 9-car train?

Heavy rail does many things well, but it's pretty inflexible.

So - unless we insist that all new stock is like a 153 - we've got to accept that we are restricted to stock with a certain multiple of carriages.

For example, SWT have to decide whether services from London to the south coast are made up of

4x20 = 80m
8x20 = 160m
12x20 = 240m
5x23 = 115m
10x23 = 230m

LM have to decide whether services from London to the midlands are made up of

4x20 = 80m
8x20 = 160m
12x20 = 240m

(etc)

Sometimes that means an imperfect number of seats, given that demand at one end of the route isn't the same as at the other end - that's life.

You keep appearing to look for a "perfect" situation, but I don't think there is one. If you would rather have medium lengths services at the "country" end, that means accepting no scope to lengthen them at the "London" end. And I think that catering to demand at the London end is more important.

Also, you need to stop seeing demand/ supply on these kind of services as being the same as today. Electrification will allow the "Swanline" services from Cardiff to Swansea to be increased to something like a 319 - much longer than a two coach DMU. AIUI IEP will see all services in the Golden Valley from Swindon to Gloucester run by 5x26m trains (instead of the bi-hourly Sprinters that provide half of the service. Services from Plymouth to Cornwall will be half hourly in future. So it's not simply a case of "busy eight coach HST replaced by five coach IEP". See the bigger picture.


If the class 387s etc. aren't going to keep enough short-distance travelers off the IEPs and every IEP out of London needs over 600 seats, then in my opinion an all 9-car fleet it has to be. This would of course result in lots of empty seats on quieter parts of the network, but that would be the case even with 5-car sets available as any demand of 327-567 passengers cannot be accomadated on a single 5-car set and would have to be a 9-car or 2x5-car formation

Okay, you'd rather we run nine coaches at all times to Gloucester/ Hereford/ Weston etc - meaning building dozens of extra carriages (especially as you can't take half of a doubled up unit out of service during the daytime to perform maintenance), meaning no scope for portion working?

If you can keep enough short-distance passengers off the Intercity services out of PAD to allow a number of shorter Intercity services (such as the 180s operated today), then it makes more sense to have a mix of lengths and diagram appropriate length trains to each service

But isn't "a mix of lengths and diagram appropriate length trains to each service" what five/nine/ten coach services gives us? :lol:

And I do believe the service at the likes of Southall or Langley will become universally known as the "Crossrail" service, as they will provide the bulk of the service.


Ah, then I've misread the contractor's (Volker) documentation.

The GWR services are not 'all stations' - just look at the timetable or Real time Trains. In the case of Southall, you are correct as the only trains calling there will be the Crossrail ones. If the current stopping pattern remains post-electrification - which seems to be proposed even with the use of faster accelerating Class 387 emus - then two trains per hour calling at Langley will be the GWR suburban services running through to Oxford. These make up one third of the train service as both peak and off-peak Crossrail trains will call four times an hour.

And I ask again - does it matter what people call the train service, as long as they know where the trains go to?

I accept the point that passengers from London to Pangbourne may change at Reading, but the main driver for the continued GWR suburban service is to make uninterrupted Slough - Pangbourne (and similar) journeys possible without enforcing a change at Reading and clogging up the Relief Line platforms with more terminating trains.

I think you are applying the current service pattern to the very different circumstances of the future. Crossrail will, even initially, be running 10 stopping services per hour on the Reliefs, out as far as Hayes where four per hour branch off to Heathrow. That's every 6 minutes. The GW half-hourly trains are going to be inserted in between these. That gives little scope for a different stopping pattern.

If I wanted to be controversial I would say it was nothing more than an Orcats Raid lookalike on the very substantial revenue Crossrail will develop, with short 4-car emus mixing it with 9-car Crossrail services.

According to Crossrail, the Thames Valley semi-fast services will only call at the following 5 stations between Reading and Paddington:
  • Twyford
  • Maidenhead
  • Slough
  • Hayes & Harlington
  • Ealing Broadway

Southall is the only station between Hayes & Harlington and Paddington at which: all Crossrail services must call; and the Thames Valley services won't. Therefore providing room for this `different stopping pattern'.

Network Rail documents recommend transferring the semi-fast Reading-Paddington paths to Crossrail once there is enough demand. The Oxford-Paddington stopping service would presumably subsequently become a fast service between Reading and Paddington, or be routed via Heathrow and take over what is presently Heathrow Express paths.

I expect that they will be at least 8 car, and possibly even some 12 car in the peaks. The Direct Award stakeholder brief already states that the Hayes EMUs will start as 4 car and then be lengthened to 8, and aren't they the sort of services that will be extended gradually to Maidenhead and Reading?

Controversial? How can the GWR service be an Orcats raid on flows that they already control?

My post about the stopping pattern of the Paddington - Reading - Oxford service was based on outdated information. The stopping pattern I quoted was for the originally intended electric service to Oxford which should have started in 2016 and therefore pre-dated the introduction of the full Crossrail service by a couple of years. As a result of superb engineering management by Network Rail the two services will now start at about the same time and the stopping pattern quoted by JamesRowden is now the currently quoted one.

Note that this pattern will still allow travel between the smaller Thames Valley stations west of Reading out to Oxford to the major centres and interchange stations between Reading and London without enforcing a change at Reading. This is nothing more than good customer service.

I don't understand the reference to an ORCATS raid. The flows are priced by GWR anyway - if any organisation is making an ORCATS raid its Crossrail! And if you read NR's Long Term Planning consultation document from 2014 you will find that 8-car emus are planned for the off-peak and 12-car for the peaks.

Well spotted, I thought I'd seen it somewhere else as well.

I think another way of looking at this, is that there can't possibly be anything like enough paths for the 387s to run around as single units all day, they'll have to run in multiple to justify the numbers on order.

If you look at the scheme and ignore some of the more fantastical claims made on fora such as these, you would get the impression people who knew what they were doing were responsible for designing the new trains, electrification and track infrastructure for the GWML Route Modernisation program.

A good point, well made.

But according to a certain senior politician, this country has had enough of people who know what they are doing. So expect a few more fantastical claims...

I don't know. But if they were all that quiet wouldn't they would have even fewer IC125 services than they do currently?

So you have no idea about the loadings at those places but still feel able to pontificate about what size of train is most suitable.

Most of the Cotswold Line HSTs do the jobs they are on because the trains are:
a. Busy, as they are in the peaks
b. Getting stock into the right place for the morning service into London - hence late evening westbound HST - or for the busy late afternoon Oxford-London services
c. There is nothing else more suitable available, due to there being only five 180s in the fleet, hence the off-peak HSTs to Worcester and Hereford.

And c also applies to Cheltenham at the moment, where 180s operated many services from their introduction until late 2008.

I've never been on the 07:30 Carmarthen to Paddington service, but from what I've seen of the other workings I would agree that a 2+8 IC125 isn't really needed west of Swansea. But I believe a shorter train would probably be inadquate further east, therefore I am in two minds about whether the through London services west of Swansea should continue, but if they don't I would want assurances that the Wales & Borders franchise would provide enhanced services between Carmarthen/Milford/Pembroke and Cardiff/Swansea to make up for the loss of through trains.

I don't think there's ever been any suggestion the Carmarthen service is under threat. GWR may very well send a five-car set out to Carmarthen and back, then couple it to another in Swansea for the run on to Cardiff and London. And vice-versa.

Did I ever suggest the whole GWML IC fleet should be 6 or 7 coaches? I don't think so, as far as I can recall I've always said that the GWML IC fleet should be comprised of either:
  • 8/9-car trains only or
  • some 8/9-car sets and some shorter ones
Which of these options I would select would depend on the maximum loading at any point of each diagram, as I admitted above, I don't know.

When did I say you had said all the fleet should be 6 or 7 coaches?

But - unless it was someone pretending to be you - you most certainly proposed a jumble of different train lengths - post 159, page 11.

For Cheltenham etc. it's too late now, but instead of 36x 5-car and 21x 9-car it possibly would have been better to have gone for around 10-15x 5-car sets (primarily as class 180 replacements), 30-35x 9-car sets and 15-25x 7-or-8-car sets. The exact proportions of how many of each would be needed is hard to say, but I feel that, with clever diagramming (which is needed for the portion working anyway), fixed-formations of three lengths (or even just 7-cars and 9-cars instead of nines and fives) would be better than portion working.

And you then start talking about 6 to 8-car trains again below....

Have I ever denied that? If the 180s aren't full at any point of their diagrams, then a 5-car IEP should be fine on those diagrams. I just don't think FirstGWR will find anywhere near 32 such diagrams, they can put the 5-car IEPs on 7-days a week. Yes, some can be 10-car in the peaks and in theroy be uncoupled at Paddington to run shorter services off-peak, but are there enough services out of Paddington that a 5-car set would be sufficient on?

There are only five Class 180s available to GWR at present, so the amount of jobs they can get cover in a day is pretty limited. When there were 14, they worked a number of other services, such as to Cheltenham and Exeter - for precisely the sorts of reasons that GWR will operate five car 800s and 802s on various services in the future. You haven't seen how they will be diagrammed, so how about waiting to see what will happen in the real world before passing judgement?

Yes, you need a full length train in and out of London in the peaks, that's obvious. But equally,
Just because there are less passengers off-peak, it doesn't mean the number passengers drops from over 600 in the peak to 300 off-peak. Train loadings are going to vary widely, some services might have 200 on board at most* but others might have 500 or more, or anything in between.

Yes, loadings will vary and the people doing the diagramming at GWR know that and will act accordingly - it's their job... But there will still be an awful lot of duties where 320 seats will be more than enough. Such as off-peak west of Oxford or on a newly beefed-up hourly frequency to Cheltenham, or some of the extra off-peak, limited-stop Bristol services....

If you want to match train-length closely to demand on each service, then you need "a random series of train lengths", otherwise you are always going to end up with either passengers not getting a seat or trains much longer than necessary. On regional and suburban services, you can do it by having short (2-car and 3-car) units that you can run in multiple to make up any length of train from 2 coaches upwards, but with 125mph stock the cabs take up too much space to have lots of short units, so the only way you can meet a demand between 350 and 500 passengers without running a 9-car unit is to have some units with 6-8 coaches.

Or you can have some units with five coaches, which, when coupled to another five-coach unit, provide much the same seating capacity as a single nine-car set, allowing a relatively straightforward stepping-up/substitution for heavily-loaded services in peak periods, minimising disruption - but you have been told all that above anyway.

Matching capacity to demand always involves some form of compromise and you have to start somewhere. That somewhere on the GWML is a mix of five-car and nine-car formations, arrived at after a fair bit of detailed and informed work - rather than being someone's 'opinion'. There is a great deal of information about loadings and forecasts for the future and train capacity in the Western Route Study and the one for Wales, which informs things like timetable planning.

* in this case, if you have a whole diagram of services like this with no busy workings, you can use a 5-car

Yes, you can, and you can pair them up to cover busy services, or in times of disruption to save on train paths, and generally allow some degree of flexibility in the fleet and how it can be used that just is not there now with HSTs.

They're more likely to know how busy the services are than me, and note that they didn't say every train had to be 8 coaches on weekdays, only in the peaks (but they did say every train should be load 8 at weekends).

Again, maybe just let the people at GWR, with the expertise and appropriate knowledge of loadings, forecasts of expected future demand, etc, get on and do their jobs. Instead of going round and round in circles repeating the same stuff over and over, despite what people keep trying to tell you here about how and why these trains will be used, including people - unlike me - with rail industry insider knowledge.

The reliability requirements for the Series 1 OLE are really rather onerous, the accelerated stress and ageing testing being undertaken by Furrer+Frey (such as the work at the University of Sheffield) and elsewhere is promising, as is the reliability we're seeing on the GEML, where the GE precursor to Series 1 is doing really good work.

There are parts of Series 1 in service elsewhere, and it's a known quantity which is why Series 1 is designed as it is - it's already making use of the best designs out there currently in service.

There's little question dewirements will be disruptive, but they're not going to be anything like as disruptive as the dewirements we see on the ECML - Series 1 OLE plus IEP with its single diesel power pack is going to make the very best out of a bad lot during a dewirement.

Series 1 is also incredibly easy to repair and get back up and running - large dewirements will be repairable in very short access windows.

It's also silly to think the OLE is going to be the source of most disruption so why bother with exceptional train reliability. We should be (and some of us are) pushing for a railway where as few services as possible are cancelled due to failed stock or lack of stock. NR, TOCs and service providers can work round a dewirement to get pax to their destination, they can't work round absent stock.

You need to prioritise. Even if there is one dewirement a month it will make anything you gain from the final 20,000mpc look like a rounding error. Your intentions are laudable, but for goodness sake focus. You have thousands of miles of remote high tension cable any one section of which could stop the job completely. MPC is not the same as availability which is also strictly contracted in the IEP framework.

Your analysis seems back to front to me - TOCs work around being -1 sets every day but wires down at Goring and it is Game Over.

Don't chase loose shrapnel when there is a boot full of tenners blowing into the wind.

The reliability figures pre-testing are for Series 1 to be twice as reliable at Mark 3b and around 20% more reliable than the Series 2 system, they'll at least match and hopefully beat by a sizeable margin the GEFF OLE (Great Eastern) and should provide the GWML with an electrified route which has overall reliability in excess of the Great Eastern with its new OLE, despite the GWML making more use of its OLE.

The benchmark or baseline was to improve WCML reliability values when the Series 1 contracts were let by Network Rail, and that's what the design and planning has all been built around.

The OLE will be sufficiently reliable to make rolling stock reliability an important and integral part of overall route reliability. The OLE is not going to be the weak link here.

jayah, Network Rail is not involved with rolling stock procurement or maintenance so I'm still not sure what point you are trying to make.

I am a tremendous supporter of portions of trains that can either be returned to the centre as demand falls off downroute, or split to multiple destinations. If the whole GW fleet was made of 5-car sets and plenty of doubled-up working at Paddington (but not at Penzance, Swansea or Hereford) that would be great.

The one issue is that as time has gone by, the old skills of the time taken to divide and combine services seems to have been lost, and it takes ever longer to do so. It's not so much the actual staff alertness, more the mechanical features of the trains, and the imposed procedures. I was reading an account from Switzerland about emu portion working where at a split point the first half was often under way again in 45 seconds! (the writer said it was impractical for someone in the back portion incorrectly to walk forward at the dividing point because the first half would be already away). I've seen main line services at Lucerne, a dead end station, reverse with a fresh locomotive consistently in 3 minutes. I would hope for such alertness of operation on the GW. Hmmm.....

We all would.

TTS requirements aside, we're looking at stock here with auto-couplers, powerful TMS computers and remote health monitoring.

IEP should be deciding whether it can successfully couple up itself and not wasting time trying to couple when there's an issue. That should similarly prevent the stock from coupling and not being able to move.

SWT can get it right with basic DMU stock, so there's no excuse for GWR and Hitachi/Agility not getting it right with the all singing, all dancing IEP stock.

Coupling of 16x sets at Reading takes about 30 seconds and is done while passengers are waiting to disembark.

I'd say GWR are already pretty good at doing this and it's hard to see how it could be done much faster.

Mark 3b? Do you mean the rubbish they suffer with on the ECML? I had hoped that given 3b is derided as not fit for purpose and nowadays not even considered suitable for anything over 100mph, that what GWML was getting would remove 90% of the failures, not half of them? This definitely sounds like one of three weak links, along with the signalling whose unreliability defies all known human intervention, and the third being largely beyond anyone's control.

It sounds like a slow bicycle race between signalling disasters and OHLE calamities then. If IEP is even half as reliable as the current HSTs and Turbos, nobody will notice the candle burning on the edge of the forest fire.

Never timed it, but with the (un)coupling of the Liverpool-Norwich trains at Nottingham most of the time is probably taken up with opening and operating the end gangways and the screens that block access to the cab. Having no walk-through between the units will help in that respect.

That's one powerful crystal ball you've got there - not one of these additional GWR services has turned a wheel yet but you know they will lose money...

I repeat, what massive ramp-up in services? The semi-fasts will run every couple of hours - that's all. They will provide some consistency in service at the stations between Reading and Taunton, where the key characteristic of the current provision is inconsistency, with some stops provided by the current erratic semi-fast service, with others inserted into Plymouth and Cornwall services, often with large gaps in between.

But I take it that's just fine and dandy in your view and the status quo is all that the passengers will require/deserve. Passengers who most certainly will be paying - through the money taken in taxes that the government puts into the railway and through the fares they pay, fares which now cover about 70% of the network's operating costs, far more than they used to.

What does the Network Rail credit card - otherwise known as part of the national debt, which is what it has always been, whatever clever accountancy and company structure ruses the Government has tried to come up with over the years to pretend otherwise - have to do with a project to deliver new trains?

I do not need a crystal ball. Of the 3 true Intercity franchises out there, only EC covers its costs, with XC and WC being subsidised by the taxpayer to the tune of £330m and £170m a year (2014-15). It hardly takes a great leap of faith to say that the most marginal and frivolous semi-fast London - Exeter trains using brand new rolling stock will not be making any money. This is a truly scandalous situation given the relatively benevolent economy and colossal investment by the taxpayer. Most businesses invest to make money, not to lose even more of it.

For the past 20 years, the industy has been living on the never-never. Reality is about to catch up. Infrastructure investment has been following train service development for the past 20 years and more, putting out fires and letting the industry build its way out of problems of its own making.

In 2015 NR paid out £1.2bn in debt interest on £38bn and now debt is rapidly heading for £50bn and with it debt interest towards 20% of farebox revenue. This cannot continue. Network Rail will own as much debt as the Scottish Government in short order and still has unfunded black holes in several of its committed major investment schemes.

Only yesterday I was watching Dyan Crowther in front of the HOC Select Committee saying that the GTR bid was told to assume 10,000 delay minutes from London Bridge remodelling in a year, only to have that total in one week. In other words, 15 years on from Operation Princess, the industry still does not have a clue about Network Capacity, let alone how this interacts with performance therefore how it needs to plan infrastructure development.

National Rail Trends shows Government Support at £4.8bn a year, well down from WCRM days, but still more than double the 1990-95 average adjusted for inflation. But wait, a new line has appeared in the table for loans to Network Rail. £6.4bn in one year. £11.2bn of taxpayer support in one year. This completely blows every other year out of the water.

Now the credit card has been cut, operations and investment are the same budget. It doesn't help that the industry is so badly planned, that the more it invests, the more money it manages to lose! Infrastructure spending no long hides in the long grass. Money wasted on new trains means less infrastructure investment and money wasted on low return infrastructure enhancements means less money for supporting ongoing loss making operations. Fairly soon, the piano wire is going to snap and it will not be pretty.

In the AT300 document it does say that Westbury / Pewsey will gain 'other' extended services from Newbury and both are already well covered in the peaks. More and more loss making trains(*) is completely unsustainable. Blowing tens of thousands per month per vehicle (extra) on a new fleet of trains because they are new, shiny, not corroded, get the Chancellor a good headline, and save 3.5mins between London and Exeter with a following wind is not a sensible way to spend money when people are dying on hospital trolleys in A&E, nor is it sustainable for the industry.

* Looking at the attachment I see 25 weekday trains from London to Exeter via the B&H excluding via Bristol and 18 currently. I am making that a 39% increase, with no increase in the peak service from London which is every 30mins as now. There will be no platinum card for remodelling Exeter, Westbury or anywhere else if it doesn't work.

.

What? You do know that you can't completely stop spending money on transport infrastructure to fund healthcare, you need funding for both. Healthcare is a separate issue to this discussion and IMO the lack of funding for it could be alleviated by slashing foreign aid and introducing charges for non UK residents.
