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.
