RZD EM2 029Vokzal Yaroslavskiy Vokzal Yaroslavskiy

Only the head car carries number 029, other cars are from EM2-031. EM2-029/031 used to be called "Sguschenka" ("Condensed milk") due to its painting scheme which was very similar to traditional one used on cans with condensed milk (compare: http://www.konfa.de/fotos/sguschenka.jpg Now EM2-029/031 is repainted to the standard white colour.

Ah ah, I see that in Russia, trains also have nicknames! Nice EMU!
But why have cars different numbers?

I don't know reasons for this particular replacement of car (they simply exchanged head cars of EM2-029 and 031). Usually cars are replaced if the original one was badly damaged in crash or by fire.

OK, thanks for your answer. We have the same thing here!
