Edit: I have heard back from OTT (remember I said I would ask?), they've asked me to stop using their map style & data as a base for the project. I have also been asked very kindly to remove all previous versions from the site and have done so.

That's a shame. I'd have hoped they'd have just asked you to credit the original in your work.



What's the next stage after the Maidenhead services introduction (apologies if this has been asked before)- will the Reading stoppers be next for 387s, or are they going the whole hog with energisation to Didcot?

Commissioning of the overhead wires to Reading - to link with the operational 25kv on to Didcot - is slated for later this year, with passenger services all the way to Didcot starting next January, as Network Rail stated earlier this week.

I must admit that I have not read all 101 pages of this thread, but I have revived a spam e-mail offering me shares in flats near Swindon station with the message "Swindon Station - Kings Cross only 45 minutes by 2018"

How feasible will this travel time be "by 2018" and even when Crossrail is in place?

By the way I have no interest in "investing" in these flats

I see this is your first post here so, welcome!

Swindon - Kings Cross in 45 minutes is absolutely impossible. Swindon - Kings Cross in 1hr 45 yes, 45 minutes, no chance.

Swindon - Paddington is about an hour right now and that's not changing much with the improvements. They might get 10 minutes off, but I'd be honestly surprised if they do more than that.

I can only imagine they mean Swindon to Paddington, which is currently an hour's journey, as you would need an extra 15 minutes to get from Paddington to King's Cross, not including waiting for the Tube.

Maybe the shared flat offers a private helicopter, that will take you to King's Cross in 45 mins? :lol:

Mostly Glasgow-ish. Mostly.
F&F Series 1 is pretty robust stuff, but in light of GWML programme changes, delays and cutbacks, can we expect to see it being used for more electrification in the long run? How many of the cost issues (if any) are down to S1? I vaguely remember Mr Phlopp mentioning it'd be used for MML, but will this now become a Series 2 or UK2 project instead?

(I appreciate this may be more of a discussion for the MML electrification topic..will follow it wherever it ends up)

I think that the 'lessons learnt' from this 'shambles' will lead to the MML coming in much more cost effectively and accurately. For example, I don't think the MML suffers from the buried cables issue and the HOPS trains can actually pile for series 1 now.

My personal MML concern is the huge amount of headspans south of Bedford that are going to have to be replaced, 'dealt with' or just ignored. It's something like 50+ route miles I think, maybe even longer.

Anyway...back on topic. What work has been done on the Welsh side?

MML definitely wouldn't be done with series 2, as that is limited to 100mph, which isn't much use. IIRC the plan is for it to be done with the "UK Master Index(?)" which is a combination of the both of them

The NW electrification up to now has only used the Omnia catenary, but someone recently photographed some newly added bits of steel work at Salford Crescent over the pair of tracks which are related to the Ordsall Chord project which appears to be using F + F fittings. Presumably, designed by a different contractor. So it all appears to be a bit interchangeable.

Will all new OLE anywhere be series 1 or will some routes be series 2 (eg Waterloo-Weymouth/Portsmouth/Exeter - which afaik don't have any sections rated about 100mph)?

Not sure on the timescale for when/if Waterloo will get OLE, but Woking-B'stoke-So'ton-Weymouth/-Salisbury has been studied for CP6; the current max linespeed is 100mph as that's the physical limit of the 3rd rail. A change to OLE could allow speeds of up to 125 on the Woking-B'stoke section of line, but whether an upgrade in speed will come to pass remains to be seen.

Series 1 for GW is for high performance 125-140mph.
Hardly any other unwired UK route is going to need that.
The MML will be some sort of Series 1/2 hybrid, and I imagine that would be used anywhere that needs over 100mph (eg XC Derby-Bristol, or Leeds-York).
The LSWR is limited to 100mph only because of 3rd rail capability.
The notion about electric spine was for higher speeds under AC west of Basingstoke.
Anyway, Series 1 has to overcome its cost and rollout issues before it is used elsewhere.

Piling is due to start in Newport very soon, according to this article in the South Wales Argus. http://www.southwalesargus.co.uk/news/15194680.Newport_residents_warned_of____noisy____railway_work

Network Rail has written to residents living near the railway line that piling work is set to be carried out along a seven mile stretch between Marshfield, east of Newport and Llandevenny on the Monmouthshire border. The work, part of a project to electrify the South Wales line between London and Swansea, is will be carried out between early April and late August.

Is this the first major programme of such work in Wales? Seven miles in twenty weeks sounds quite quick.

First significant section yes, there are a few masts up around Newport but I'd imagine now that all the preparatory work is done things will visually appear quite quickly.

It would still only be a two track mixed traffic railway west of Basingstoke, fairly busy with 75 mph freight. A higher maximum speed anywhere would just catch up the train in front sooner...

Meanwhile, back in GW-land...

To aid jyte's map-making, the piling already installed between Didcot and Oxford ends just short of Kennington junction (where the Cowley branch diverges). There look to be one or two short gaps in places and a few part-driven piles still to be finished off, but most of the work has been done, so I'd expect that once attention eventually switches back to this area, steelwork should appear rapidly.

Contrary to what was said earlier in the week, there is no steelwork out of the ground yet around Didcot North junction - the only uprights are those at Appleton level crossing and for a short distance from there towards Didcot.

What happened to the 'pause' or whatever they called it of that part of the electrification?

I think someone pointed out earlier that Didcot-Oxford was the first section to be piled before they realised they had to remodell Oxford station before they could electrify it, and that hadn't yet been done.

Also, the Sectional Appendix (which I've been using to make the map) makes it look like the curve that serves platforms 3-5 from Oxford (I forgot its name) is now actually electrified to about half way along. Is that correct?

That matches another map-type source I've got access to which suggests that it's electrified up to just past the sidings on the down side.

It is still paused, but the piling was done some years ago, because, as jyte says, Oxford was initially supposed to have electric trains running by last December. Overhead wires will be installed from Didcot up to Appleford this year as part of the preparations for electric services to start serving Didcot next January but that is as near to Oxford as the wires will get for at least another couple of years.

I wish people would stop confusing electrification of the Oxford station area with the potential building of a new and expanded station and associated extra trackwork this would require - a shiny new station is a nice idea and long overdue, but funding to do something on the scale the city and county councils seem to want has yet to be found.

The key issue holding back electrification at Oxford at present is the need to renew the signalling. The existing kit is life-expired and not immunised against 25kv but work to replace it has been put back several times.

The most recent version of the electrification plan I saw at a Network Rail event last year essentially involves wiring up the existing layout at the station and the surrounding area as far north as Wolvercot junction (where the Cotswold Line leaves the Banbury route), with a few modest changes, several of which are already in hand and will be completed ahead of or in conjunction with the resignalling.

These include relocating some points at Hinksey and just south of the station, remodelling the stabling sidings north of the station (and access to them), making Oxford North junction a full double track junction to meet the needs of East-West Rail services, plus the commissioning of the extended down loop line from Oxford North up to Wolvercote village.

On the curve at Didcot the wires end somewhere south of the Transfer Shed at the railway centre (the long building at the north end of the centre site) but as I usually pass on expresses on the avoiding line, can't be more exact than that, I'm afraid.

Okay. Do you know the timeframe for Oxford electrification?

A change to OLE could allow speeds of up to 125 on the Woking-B'stoke section of line, but whether an upgrade in speed will come to pass remains to be seen.

In light of:

- The prospect of ole not reaching BTM for several years if at all
- Ditto Cardiff - Swansea
- Ditto North of Corby
- Ditto Trans Pennine

because of the massive cost overrun on the GWML scheme then why does anyone think that the SWML is going to get ole in the next 25 years? It was a scheme of dubious financial merit when it was announced and now it has no merit at all.

Oh and to anyone who spouts the old chestnut about the Bournemouth line substations needing replacement, I say look at the cost of substations and compare that to the cost of ole, structure alterations, resignalling and adding AC capability to the rolling stock. You'll get a number for the former and an absolutely gigantic number for the latter. Which one do you think the DfT are going to sign off on?

Might we try to stay on topic and not drift off into what might or might not happen in the future on a completely different route?

I think this is back on topic.

According to some posters at RMWEB, as of the 27th March Maidenhead's platform 5 didn't even have SPS installed.

Is this true?
