E1 4863 and c4 trailer 1372 are heading to Oper on Wiedner Hauptstraße. Both are in fairly original condition and as late examples of each type have have door side destination blinds and also no opening windows on that side.

Although I cannot find any evidence to support this, I suspect that these late examples had to work together as the destination blinds were electrically-operated and the trailer would need to be coupled to a compatible vehicle. The blinds seem to have been removed from all c4 trailers and those without ventialtors have had some added in a rather random fashion in the intervening years.
