Do we know if this is an ex-458/0 vehicle or a former 460?
And will all the 458/8 vehicles - regardless of pre-/8 life - look identical, or will it still be possible to tell which was which? If you actually compare the fronts of a 458 and 460, there are some notable differences (such as to the design of the top light, and placement of the destination board), where as Monty's scan looks very like a 458/0 in those respects. Will they spend extra time giving the 460s cosmetic surgery to look like their equally-weird looking sisters?
And given that the 460s didn't have any form of gangway at the front (which will presumably require considerable work to implement), will the cabs inside need to be modified or rebuilt accordingly?
Also, what is with those lights? It's like Southern's refurbishment of the 455s - if you're trying to bring it up to the standard of modern trains, why use such a bizarre headlight cluster?
