I'm not sure if this has already been referenced but this article from the IRJ confirms that (a) the ETCS▸ controlled section of the line ends 4km from the accident site and (b) the Alvira type train involved in the accident are not (as yet) able to use ETCS on that section of the line. http://www.railjournal.com/index.php/europe/etcs-not-operable-on-santiago-crash-train.htmlTherefore the train was under full manual control for the complete journey from Ourense to Santiago under the Spanish ASFA system which, like our AWS▸ , monitors acknowledgement of the lineside signals but (unlike TPWS▸ ) does not provide any form of speed supervision. So, other than the driver's vigilance, which appears to be lacking in this unfortunate accident, there was no other system in place to prevent trains entering the curve at excessive speed. As the article states, even trains which are equipped with ETCS are only advised that automated supervision is disabled at the ETCS/ASFA transition point, there is nothing other than the driver's route knowledge to enforce braking prior to the curve. As we found out at Morpeth on a number of occasions, this appears to be an accident waiting to happen.

Having heard the presentation to the IET▸ at Swindon a few weeks ago and having travelled on the 395 (Javelins) I am expecting good things. Hitachi whilst they are "building" (or should that be assembling) the units the interiors are specified by the TOC▸ 's
And speaking to the FGW▸ IEP▸ project manager (name escapes me) at the same presentation in Swindon, it seems that FGW are having a significant input into the interiors. Whether that is a good or bad thing is a matter of opinion but I would hope that they reflect the quality of the HST▸ refurb in first class and less of the rather cramped perspective (although I find the legroom OK) of standard class.

...DfT» have said they want electric trains running between Reading and Oxford by the end 2015!!!!
Looks like Network Rail and their contractors (Amey?) will need to get a move on then! Most of the civil engineering required for electrification clearances between Reading and Oxford is either complete or under way - though the station footbridges at Goring and Cholsey are still to be replaced. Also I thought that the Reading flyover wasn't due for completion until 2015. There are a few foundations in place west of Pangbourne and a load of electrification and signalling components stored at Moreton Cutting east of Didcot. Foundation locations have been marked out for much of the way between Didcot and Tilehurst. I will also be interested to see what electric trains DfT plan to run by the end of 2015. The class 319s originally mooted for the GW▸ suburban services won't be refurbished by then and if transferred in their current form will go down like a lead balloon. I have my doubts if these will be used as they'll take up too many paths on the main lines with their 100mph top speed - not much better than the turbos. What's required is 110mph performance like the class 350s on London Midland. Perhaps the new dual-voltage units recently ordered from Bombardier by Southern will end up with us but I would have thought that would depend on the Desiro City units for Thameslink being delivered - and they aren't due until 2016. Headspan is almost certainly out of favour for all new electrification, my guess it will be a mix of masts with cantilevers, portals and things called twin track cantilevers, the current requirement is for what is called "mechanically independent registration" which basically means if their is a rip down on one road its does not effect the other roads, also with headspan if a span wire in insulator parts company the contact wire goes out of registration then there is high risk that whole lot can come down across all roads when a pan get ensnared
This appears to have been installed at Reading New Junction and around Reading station. Headspans are used in the new depot sidings but speeds are low there.

Thank you for that heads up FremlinsMan.
I think though it is very short notice for most, if not all, of us.
Just the sort of event I'd like to attend if I'd had more notice.
However, if you, FremlinsMan, or other Coffee Shop members, do attend, then please do report back here.
I can't make it, so I'd also like to hear a report back. I assume IET▸ members get a few week's notice of such events, but I only got the e-mail about this yesterday around 3:00. Thanks for the heads up FremlinsMan. It's local to me so I've registered. Happy to report back.

Yes we anticipate traffic chaos! Diverting the local traffic through some of the villages like Denchworth won't be terribly popular either. However I can't think of any alternative.
Good point about allowing for four-tracking though I doubt if it'll happen except at Challow and maybe Wantage Road. I spoke to Richard Turner, Community Relations Advisor - Electrification for Network Rail. He emphasised that their budget for the project was very tight (well, he would wouldn't he) and that the bridges were being replaced on a like-for-like basis. This meant that any improvements - such as road widening, footpath improvements - would have to be funded from elsewhere, such as the local authority. Given this is Oxfordshire, it's unlikely to happen. There's controversy over the replacement of the footbridge in Hinksey at the moment, as Network Rail will only fund a basic replacement, whilst the locals want the replacement enhanced for disabled access. There's a standoff over who funds any enhancements.

All across the Great Western territory / Introductions and chat / Hello from the Vale of White Horse
|

Hello everyone. Joined this group after lurking for a time. I use FGW▸ from Didcot once or twice a week for business trips to London. Also occasional leisure trips to London, Reading, Bath, Bristol and further afield. Live in the Vale of White Horse within (distant) earshot of the line - when the wind's in the right direction. Have travelled on the Great Western Main Line since - oooh, the days of black and white. Have been on:- - Steam hauled expresses from Cardiff to Paddington behind Castle and Britannia class locos
- First generation diesel hauled trains - Westerns and Peaks on InterCity expresses
- InterCity and Network SouthEast loco hauled services - class 47 and 50 locos
- HSTs▸ since they were introduced in 1976
- Every type of first generation DMU▸ that plied the line
Looking forward to acquiring my Senior Railcard later this year

Thanks for posting the links, and welcome to the forum.
Is there a similar application in for Goring's footbridge yet? I wonder whether the opportunity to extend the 'down main' platform will be taken at the same time at Goring, given that it's current usable length is just 69 metres, and if 4-car 20 metre electric trains will be using it that's not long enough without SDO▸ being used.
The case for lifts being installed is a difficult one. There's a similar argument for other stations where footbridges will need to be altered/replaced as part of the scheme, and (as is the case near Oxford) others are, or will be, pushing for disabled access at 'their' bridge, but obviously the cost to each location of providing lifts or ramps eats into the budget.
Nothing on the planning application section of South Oxfordshire District Council's website yet so it seems that the plans for replacing the footbridges at Goring and Cholsey have not yet been submitted. Moving further west, I understand that bridge replacement between Didcot and Swindon is scheduled for next year. The A338 bridge at Wantage Road (Grove) is planned for demolition on the weekend of 39/30th March and will take around 6 weeks to reopen. The A417 bridge at Challow is slated for demolition on the weekend of 11/12th October 2014 and will reopen in mid December. I'm not sure about the timing for the other over-bridges on this section but I believe that bridges at Basil Hill Lane (entrance to Foxhall car park, Didcot), Steventon, Shrivenham, Bourton and on the east side of Swindon will be replaced.
