Ok, adding a few more pics.
Type T subway as used on U6 line. Older U6 cars basically look like E2.
Type C1, taken out of service in 1996.
"Silberpfeil" (Silver Arrow) subway, used on all other subway lines. Apart from buses most hated vehicle all over Vienna. Interior kept in an ugly orange.
F, my favourite vintage tram. Taken out of service about the same time as C1.
