Verehrte Eisenbahnfans,

ohne jetzt alle 1215 Beiträge zu diesem Thema durchgesehen zu haben, kann ich mich nicht an den folgenden Beleg/Eisenbahn erinnern:



Die "Washington Park Zoo Railway" [1], auch mit eigenem Duplexstempel:



"In 1961, the Washington Park and Zoo Railway became one of the first recreation railroads to have its own cancellation stamp. With the demise of the Railway Post Office, the zoo railway is the last operating U.S. railroad with its own authorized railway postal cancellation to continuously offer mail service.

Mail deposited in mail boxes on the zoo grounds or on the locomotives is hand-canceled with the Washington Park and Zoo Railway stamp. It has become a collector's item." [2]

Beste Grüße,
Peter
