Do you happen to know what the rationale was for this? Cost reduction? Maintaining the parts of the building currently in use for other purposes (shorter trains presumably need shorter platforms)? Minimise distance between local services to facilitate inter-modal exchange (MetroBus and MetroWest)? Something else? When might the public get to see a draft masterplan?
One of my last jobs as an NR train planner back in 2012 was on this project, and I remember pointing out that putting the IEP services into those platforms did not make any operational sense, as following requadrification of Filton bank, they would conflict with anything using the Filton Relief lines at Bristol East Jn. At the time it was possible to accommodate all the proposed additional trains as a result of the IEP project without needing the additional platforms at all. Since then I expect the plans for other projects have developed further resulting in the present situation.

Presumably though you would want the new platforms to be able to accomodate IEP so some of the other platforms can be closed for maintenance even if not used on a regular basis.

Yes, obviously on a growing railway serious proposals for additional infrastructure are very welcome, the point is how it is to be used.

I guess if used for Metro services the north side platforms could be shorter, probably affecting the oldest part of the station rather less. The IEPs via Parkway would be best in the middle of the station and those via Bath in the furthest platforms as now.

Indeed, but it gives one a long hike from the taxis and buses with cases. Admittedly, this was always the case with arriving trains. The grand front entrance now leads one just to a poky Voyager for Brum. :) . Travelators from the east side would help and also an escalator from the subway to the main platform 3 / entrance. Perhaps taxis could collect pax at the new entrance on the space vacated by the demolished GPO Building in future?

I am afraid TM is compromised by its listed status for modern interchange purposes and its location and historical development, resulting on all those squealing curves. Its ideal location would have been on the Bristol Harbour Railway near Princes St.

Would the two (?) platforms in the Digby Wyatt shed take care of all the Metro services that use the slow lines via Lawrence Hill? If so the fast London trains could use the platform in front of the main barrier instead of that Voyager.

There was a plan kicking around somewhere to put a new concourse under the forecourt which would link one way to the subway and the other to the Digby Wyatt. Is this still being considered?

Work seems to be steadily progressing at last around the Reading area as Electrification works saw the MPVs out in force between Reading and Swindon over the weekend. Noticed the canopy at Didcot has rather crudely been cut into as well, but more interesting to see was - a few years early and before most of the works start on our branch, was the first signs of work on the Basingstoke Branch already with several piles already now placed into the ground running south from Southcote towards Green Park & the former landfill site, and the first bridge replaced with a new concrete one (near the future site of Green Park).

Couldn't find any references to this but whilst returning from Cornwall today, I noticed 'half gantries', (single sided lattice supports and arms) spanning both tracks of the western chord at Reading. Not that familiar with the route but I suppose they are part of the electric spine work onto the Basingstoke line.

Reading to Basingstoke has now been moved into Great Western electrification, presumably so that it's finished in the same sort of timescales.

The recent schemes seem to be a little more 'generous' in their infrastructure provision than BR-era investments. What you saw is (in my opinion) probably no more than provision of an escape route in case of a failure on the approaches to Reading Station's east chord.

Although it can't hurt the case for pressing on with the spine asap.

Slightly off topic but I heard today that North Pole depot is now available for use again from this week. I am not saying that it will be in use any time soon but it can be used IF required.

The new Modern Railways says that to avoid the embarrassment of having IEP available but with little or no opportunity to run in electric mode and unable to keep to the timetable, NR has decided to focus the electrification effort on London to Swindon.

Quite a lot of uprights and even horizontal sections are up between Maidenhead and West Drayton, along with bases mostly installed. Looks like things are finally picking up :).

Yesterday and the day before there were electrical supply issues around Acton, leaving Heathrow Connect unable to stop between Paddington and Hayes.

It's about time!

I wonder when the registry arms and associated paraphernalia will be put up...

If the publicity material from Furrer + Frey is anything to go by, that shouldn't take very long, but then again, the piling wasn't supposed to take this long either!

Is there any news on when electrification progress will be made through Sonning Cutting ? I passed through there yesterday and can't see any evidence even of holes to hold those metal foundation tubes

They use the 'piles' (steel tubes) to make the holes. Pile driving?

You shouldn't ever normally see holes without the piles in place.

Indeed, as they are leaving the pile tubes in situ and filling them with concrete to hold the catenary supports/gantries.

I don't even think they normally fill them, they might sometimes just top off the interior with concrete. The local ground level they are piling into will remain within the tube, and the top of the tube has the female threads factory fitted to take the mast, gantry or whatever. Many of the piles west of Reading with masts already fitted have a clear space beneath the mast, which shows the empty space at the top of the pile underneath clearly.

When I was travelling from Reading to Cheltenham last week I just noticed a lot of the piles filled/topped with concrete around the masts installed within them. Of course, I couldn't tell how deep the concrete was, and I had assumed that the 'ground' within each tube had been removed and replaced with concrete.

They may have been designed for both options. In some areas the ground will be strong enough for the pile to work just using the friction down the outside of the pile. In other areas with weaker ground, it may be necessary to fill the pile with concrete so it can get capacity from bearing on the ground at the bottom.

The concrete ones you have seen are the ones that the ground has basicly been drilled out and filled with concrete. These have bolts set into them for the masts. The steels ones are just hollow tubes knocked into the ground and thats it, no concrete fill at all. They have holes in the top that have 6 stud put through then the mast on top. Which type is used where depends on alot of factors like ground conditions, mast to be used and load carried or pulled against.

Masts are slowly arriving and the teams are getting them up as quck as they arrive, as for the rest, who knows. The booms are mainly going in on weekend blocks when all 4 roads are closed, but I have heard that there is a plan to get a 50 minute window each night where it may be possible to do a boom.

Supply of materials is the main issue, we seem to get a week of work then a week waiting for supplys then back on again. I can only see this getting worse as they are only ordering exact amounts for each section and the materials are coming from Italy. Why they can't order a stock of stuff and then just move it along the line as its used up, I mean this is the start of a 180 mile 5/6 year job with the same gear all the way along.

The main delays have been caused by piling issues, once the main booms, masts and TTC's are up the rest will fly along as long as the supply of materials is there.

A quick question about the GW electrification at Newbury... is the existing footbridge to be jacked up or will a completely new replacement be built? I am told it is too low for the wires as it is.

Hi, the question on the footbridge at Newbury is a good one and even through I live in Newbury, there's been no word on changing it as far as I know. The one at Thatcham station has just been changed, but Newbury's is a much bigger one & they maybe thinking about adding lifts if possible.

Anyone with more informed knowledge??

thanks,

That's very interesting.
To my eye, there are mountains of supplies stockpiled at Moreton (piles, masts, booms etc).
What supplies are they short of? Small piece stuff to go on the booms?
It's very evident that no registration gear has yet gone up.

To be honest we see exactly the same as you and we're baffled by it. There are men and machines waiting for materials but they are only releasing them on a week by week basis, i.e a mast may have a schedule for Thursday of week 17, thats when it will go out. But the crane may have done this weeks work, but it can't take that mast until the spec date<(<(

This is all well if possesions are on time and no problems, like the 3 hrs lost on Tuesday beause of the incident at Ealing, or track maintainance needing doing so limiting the available time and worksite of the OLE crews. Add in the safety side of always planning for the worst case that may never happen in a month of sundays, meaning lifting a mast in is a 2 lift job, 1 off the machine horizontally and into the cess, then resling and lift vertically into place, all because the sling may break if you lift it vertically straight off the machine and that could block the 2 open lines and cause a crash:roll::roll:

I think alot of the short stuff is the brackets for the booms, with the way they are planning it I would be very suprised to see any registration gear for a couple of months. Someone somewhere has a plan, would love to know it:lol::lol:

Other delays come from minimal access points for machines, its taking nearly an hour from getting on track to get to the work location, so you have to leave earlier too.

TBH they have some very good linesmen teams on the ground, but they are not being backed up with the materials they need. They need to get a minimum of 2 weeks supply in front of the teams and preferably let them just keep going each night starting from one end of their section and working through. Over stock the machines each night (if the plan says they can do 10 brackets a night give them 15), then any extras done are a bonus. The OLE teams can pull some of the overrun back if they have the gear ready for them. And by that I mean if a section need 100 brackets of one type don't just order 100 order 120 as some bolts will be seized, some will get dropped and lost ect then bump the surplus onto the next section. The only time there should be a wait for materials is on the last few sections.

I believe the footbridge at Newbury is to be replaced.

EDIT: Actually I may be wrong on this. I shall try and double check tomorrow.

I'm guessing you are on the eastern (Crossrail) section.
Maybe supplies are organised differently to the Amey stuff further west.
The logistics sound like a nightmare.

It was listed in a Network Rail planning document listing all the work to be done in West Berkshire:

Newbury Station Footbridge (No. BHL 5305)
17.2.15 The footbridge provides access to the two platforms of Newbury station across the BHL. The bridge would require demolition and reconstruction to create sufficient clearance for the trains and OLE to pass underneath the bridge. It is proposed that the worksite and laydown area be located within the station car park, north of the station. The works would commence in September 2013 and would take approximately 12 weeks to complete.

That date doesn't look right though, unless it was sneaked in 2 years back with no-one noticing... :D

Yes, I believe (according to the company newsletter) that the works shall be beginning soon. Installation of lifts will also be commencing at the same time. I'll be odd and a bit sad to see the old footbridge go. Been using it since I was a kid. My Great Aunt used to have a flat that overlooked it. Used to watch the trains going through the station out of the bedroom window when I was very little. Still, it's got to be done!
