Surely the sloped front is irrelevant for platform length, it's whether the first/last sets of doors are aligned that's important?

Plus if the driver can see signals and mirrors and so on, but they're a lot easier to move than extending platforms.

You're forgetting that two middle cabs in a 8 formation adds significant overall length, pushing the rear passenger doors further out of the platform. 710s are not authorised to use any old 315/317 DOO platform equipment like 'mirrors' either. Also, 315/317s stop markers were to align with the stop marker in the side window so the front of the train was always in line with the stopping point. 710 stopping boards you stop with the board in a side window that is located at a 45 degree angle to the left from forward. The positions for the most part haven't changed, just replaced. So when you stop you are at least a metre from where you stopped in a 315/317, pushing you further back. Generally, you cannot move a stop board forward closer towards a signal to compensate so the only solution is to cut out the last passenger doors that have now found their way either off the platform completely, or in an area that is dubious. You then have to add a buffer for the slight variations each time a train stops. No two trains will ever stop at precisely the same position. At the locations I said above these were borderline with the old stock. On an 8 car 710 they aren't even nearly in.

It's the extra length of the sloped cabs in the middle that cause the issues. The driving vehicles on a 710 are 21.4m, so there's ~3 extra metres of train in the middle compared to existing stock which means that everything on cars 5-8 is also shifted back 3 metres
Fair point, I didn't think hard enough to realise that!

Hi, have 710256 and 710270 entered service yet please? I believe they were the last of the four cars. :)

Maybe they have decided to renumber the 5-car units as 7103xx to make it easier to distinguish the 4 and 5 car units?

Currently numbered 710274/279 but to be renumbered 710374-379 before use in passenger service to avoid control confusion

7103xx test run on DC Monday 15th
Should be 710276 (as is)

Could have been solved by adopting the much sharper slope and Electrostar-like cab design of the Class 701.

How is it that control manages with units numbered 378257 and 710257 (and will in due course manage two units numbered 256) but can't handle 710273 being different from 710274? More to the point, the Overground controllers managed 378206, 378209 and 378232 being different from the other 378/2s for a while without renumbering.

I would guess because 378257 and 710257 are very different numbers for very different trains, whereas 710273 to 710274 is a change of just one. In fact, I typed it wrong while writing this out.

Or 710256/257 are the two DV units that live at Ilford and being 259/273 back.

For info, 710376 and 710377 were outside the Bombardier depot at Willesden yesterday, having been re-numbered from 276 and 277.

Are these the only two being re-numbered? Why have they been done?

Indeed it is, working 5Q72. Traction provided by 37510 and 37611 if anyone wondered.

Hi, was just wondering if anybody knows why there was a 710 over at Gatwick? Didn't catch the unit number
