This is a rare chance to have the Reichsbahn town or city you have wanted custom made, and add that rare piece to your collection. You can also have a fantasy town or name, or even your own home town, or even leave it blank.
Here is a small list of towns, there are dozens more that I did not list.
We can make any of them custom for you:
RBD Frankfurt / Main
RBD Munster (westf.)
RBD Frankfurt (Oder)
