public transport in Cairo


I’m very new to OSM but I enjoy tagging and mapping a lot so far. As I don’t know my way around JOSM and all the conventions in OSM I wanted to ask here before I seriously damage some things unknowingly:

I live in Cairo, Egypt and I think the public transport system is not as well tagged as it could be. I don’t think the metro stops show which line services them. Also comparing the tags with the Public_Transport wiki page it seems like they follow a different (outdated?) scheme.

Could someone maybe have a look at this node of a metro station (and on the railway around it) and set things on both so that everything is as correct and related as it can be? I would love to check out how you do it and then apply it for the rest of the public transport in Cairo.

Many thanks.
