Dear ORM community,

today and yesterday, I spent quite some spare time on completing the ORM train protection tagging scheme. This was done by a thorough Wikipedia search in various languages and by knowledge which I acquired from two railway signalling courses at my university. The result is a Train Protection Systems section which is now separate from the Tracks section. It contains much more systems and system levels/versions than before, shows the systems full name in the native system language and grants every system a Wikipedia link with background information.

With 33 systems, up to 6 versions per system and the possibility of dual signalling, I am worried about the current legend of the signalling layer. However, I also have some ideas to reduce the complexity. In order to prevent a technical discussion through email, I'd like to propose to have a video conference on the signalling layer. It would in my opinion be ideal, because it can be combined with giving each-other updates on mapping/coding projects and planning. I hope to see your opinions on this approach. Thank you in advance.
