Hi team, I have searched high and low on this. I have pulled up multiple route manuals for any route that has the ICE trains, I've also pulled up manuals for train Sim classic routes that include this type of signaling in locomotive in hopes I find my answer, but no luck. Searching Wikipedia or real life signaling charts didn't give me any help either. When running with PZB there's time where the signal will have a lamp lit with a number such as 6,8, etc. I'm aware of what the numbers mean but what does a lamp lit with the letter R mean? I would have thought restricted but I was able to proceed at designated line speed without any issues from the system. Thank you so much.
I maybe wrong but I think I read somewhere that it’s a routing letter, and diesigstes the first letter of the next station, or main station. It means nothing with no action to be taken in game. http://www.sh1.org/eisenbahn/snzs.htm
