Yeah, most german steam engines were black and red, with prussian engines being green and bavarian being at least partially blue. Apparently in 1925 there was a central locomotive committee which decided that colour scheme because those two colours were the easiest to manufacture without being dependant on raw materials from foreign countries. Up until then most train related things weren't centrally organized so the states did their own thing. Afterwards engines even already in use were repainted to fit the colour scheme so most of the surviving steam engines were indeed black and red instead of their original colours.
The car in the thumbnail seems to be a Yugo or a derivative.
