At Lichfield Trent Valley Low Level down platform there is a plethora of signs. Starting at the far end of the platform and working backwards they are: VT 10, Class 390 9/11 (a), 8 car,
VT 4/5, 4 car. The 8 & 4 car signs are for LNR 350s. The reason for 11 coach 390s stopping earlier than 10 coach voyagers is due to the high level line bridge support being too close to the platform edge. With the 10 car sign 2 voyagers are clear of the bridge. With the 9/11 sign a 9 coach train is clear of the bridge and an 11 coach train has the 10th coach under the bridge and passengers are not allowed to alight (b), but the 11th coach is clear of the bridge and on the platform.
(a) Not having been down since pre-Covid I think the sign says Class 390 not VT, which would strengthen the claim that VT stands for Voyager Train, but I am happy to be corrected.
(b) Presumably this is done by the guard locking the doors on the 10th coach at Tamworth because, as far as I know, Pendolinos don't have SDO and trains that stop at Lichfield also stop at Tamworth (No crossovers between fast and slow lines between these stations)
