Hi everyone,
maybe that's interesting for you:
here I've got three pics of Bayerisch Eisenstein I had taken in years 1988, 1992 and 2006 showing the changes of the same perspective.

1988 the DB-track still ended directly at the iron curtain. There was a simply fence and signs with "Landesgrenze". On the czech side there was no rail traffic anymore.

In 1992 the czech and german rails have been connected again. On the new platform there was a little costum cabin, but you had to go to the station building for passport control. To see is a railcar of the CD on the way to Pilsen (Plzen).

In 2006 the costum house had been abolished and nowadays there aren't any passport controls. It's because of the "Schengen-Abkommen" of the European Union.

And here's a Photo of 1988 from the street side of the building with the border fence. Inside the building the border was only marked by a thin iron chain across the concourse, where it was no problem to take a step into the eastern bloc ;-)
To the history of the station: the Waldbahn was constructed as a part of the long-distance rail between Prague and Munich and Austria/Italia. The station Bay. Eisenstein was border station, but there was never really border traffic with trains that went the whole line across the border. Passengers had to change the trains at that time on the same way like nowadays.
So a bigger depot was necessary. It's very unusual for bavarian endstations of this cathegory to have a turntable and a roundhouse at all.
Eisenstein got also large good shelters and much more railtracks than nowadays.
But the difficult and precipitous track on the czech side was the reason that the Waldbahn became already after opening only an regional railway without international and long distance traffic. Today the mainline to Prague goes via Furth im Wald.
I hope it was comprehendible what I mean, my English is not so good.
Greetinx from Munich,
Georg
