Jurgen,
Many thanks, any reference to Wuppertal is most welcome.
I see the trains miss out Koln Hbf and use Koln West, strange for an international service?
Many thanks again.
David
I should have looked the thing over more before posting. I think the 'm' in Dm 80040 stands for "military". The train is most likely a troop train, and the postal wagons just went along for the ride.
I also noticed that the Grss-v's only got as far as Aachen, so they have nothing to do with Wuppertal at all.
So how do you feel about adding a troop train to your operations?

Image showing that DBP coaches ventured outside Germany.
The train is an Italian working arriving at Brenner Austria, so add postal coaches to International expresses.
First coach and the seventh are Postal stock.

Folks,
Yet another enquiry.
Trying to make up plausable postal workings for the Bahnpost area.
Would Ferry vans be used for conveying International post?
Grusse,
David
