Hi Stewart,
in a discussion in the Länderbahn - discussion forum
http://de.groups.yahoo.com/group/LBF/ the question was not finally decided ( if I rember right ), how long the last perron-signal survived, maybe in a small branchline-station, with or without function.
But you can also, ask Tobias Frydman directly, what are the latest news about this topic, he is speaking Englisch perfectly and I'm shure he will reply truly, not only to sell one more kit.
I will also ask again in forums, maybe one of the easiest ways is to ask epoche-2-fans, if they know pictures of bavarian stations in era II, where still perronsignals can be seen on it. So I will also ask here
