Yesterday I was trainspotting in London. I was arriving at London Bridge on a 456 from Victoria and 3 tracks away from me on the right passed 377165 on a service to Brighton. As it went past I looked around and at the rear it was also numbered 377165. Now could anybody explain this to me? I have a few theories of my own possibly of two units getting accident damaged and them reforming them to make one good set and renumbering them like they did on c2c with 2 357's. Or that they've somehow managed to incorrectly number 377465? I know neither of these is likely but if anybody could tell me why it was carrying this number or if anybody could provide photographic evidence of it to make sure it wasn't a mistake I would be very grateful. Many Thanks.
