Are they just like taken from the existing production line? So in theory there would sort of be a corresponding S7 -1? If you get what im trying to say?

No, they've just borrowed a carriage from another unit. There will be three of them in total. It's a temporary thing to cover the 37 S8s that are going back to Derby ( not all at once! ) to have their wiring looms replaced.

Can I just ask about the S7+1s are they -
A) an S7 with an S8 carriage inserted
B) an S7 with another S7 carriage inserted
C) an S7 with another S7 inserted but the extra coach has some transverse seats?

Thank you:)

Have they corrected the issues with the shoe's randomly falling off? (i think it was last summer when that started happening though).

Modern Railways said its in part the wiring isn't up to standards for new signalling plus bogie issues.

But hang on, Isnt the new signalling also Bombardier Produced? You'd think that even considering to make their trains compatable with their own signalling (let alone standard signalling) would be on their design / build list but obviously not...

If you remember the re-signalling contract was relet last year (2011) after the original contract was cancelled. It is most likely that the problems with the wiring on the trains is due to the substitution of a completely different signalling system from that specified when the S stock was ordered.

I thought it was going to be relet but wasnt? Certainly all the articles around the internet i can find lead to one and only one certain mainufacturer. Yes, Dear Old Bombardier again - The Bombardier CityFlo 650 System. If this is the case, then it's just as well their not producing the Thameslink ATO trains then.

Bombardier to upgrade the signalling on four Tube lines

London Underground has awarded Bombardier Transportation a contract valued at approximately £354m to upgrade the signalling on the Circle, District, Hammersmith and City and Metropolitan lines.



Alongside a fleet of 191 new air-conditioned walk-through trains already being rolled out on the Metropolitan line, the new signalling system will enable passengers to travel more quickly and frequently on all of the subsurface lines, which together make up 40 per cent of the Tube network.

Overall, the upgrade, which is due for completion in 2018, will provide 24 per cent more capacity on the District line, 27 per cent more capacity on the Metropolitan line and 65 per cent more capacity on the Circle and Hammersmith and City lines.




.

London Underground has been working with and learning from other metros around the world in order to identify innovative ways to upgrade the Tube while minimising disruption.

As a result, Bombardier Transportation, which recently upgraded the signalling on the Madrid Metro, has committed to installing and testing its CITYFLO 650 automatic train control signalling system without any need for weekend closures.

There will still be a need for weekend closures to upgrade track and platforms, but these will not be the full line closures that have been experienced during previous upgrade work on other lines under the public-private partnership (PPP).

Mike Brown, London Underground’s managing director, said: ‘This is a major step forward in our plan to upgrade the Tube and will mean faster, more frequent and reliable Tube services across 40 per cent of the Tube network.

‘We know that line closures are disruptive to our customers and, as a result, we have insisted on the delivery of the new signalling system without the need for the kind of closures we have seen on other lines.

Somewhere, not in London
They missed off the Piccadilly Line, this will be receiving the same signalling system as part of the upgrade programme due to the shared sections of track on the Met and District lines...

The original contract for the signalling was with Westinghouse (Invensys) which is why there was the issue with the Picc and Met sharing tracks to Uxbridge with different signalling systems.

The S stock was presumably designed for this system. When TfL bought out the PPP the signalling contract was relet to Bombardier.

I understand only about half the S stock needs modified wiring so I assume that Bombardier was able to modify the wiring of the later units to accept the new signalling system.

PS What is standard signalling as mentioned in your earlier post?

Will point out that it's only 37 of the 58 S8's going back. If it was a design issue with it then they'd all be going back as deal was announced after all had been built. It's a sub standard cabling issue.

S7 21315 was in service as train 700 yesterday (28th November), and 21313 was running on the 21st. That means all 7 S7s that have been delivered so far have entered service on the H&C, although of course only one will be used each day until the timetable change.

And to think I missed that when I could quite easily have gone to have a look :(

But... just to clarify, was this at Baker Street or somewhere else?

S7 21313/14 successfully completed an empty test run to Barking and back, after the morning peak today, getting things ready for the start of passenger workings on Sunday.

Short video of the stock on pre delivery test this week (4th December) at SERCO Rail test Old Dalby test track. The stock is stabled in the extensive former Asfordby coal mine site and then taken up each day to the electrified 4 rail scetion at Old Dalby
Bizzare seing all the brightly painted LU stock sitting in the the green Leicestershire countryside
