Neat … the public transport issue is unfortunately a big one, and the hardest to solve :(

Not just the live updates and departure/arrival times, but starting with the sheer existence. In the (reasonably big) city where I live the only thing to be found in OSM/CoMaps/OrganicMaps is the subway.

No buses (including nightbuses for when the subway doesn’t run), no commuter rail for the surrounding cities and suburbs, no tram …

Not sure where this data could be accessed …

EDIT: Now that I’m looking at it again, it seems that at least some bus lines are available in OrganicMaps, but you have to look for a stop, click on the line, and it will show you the route. It’s not integrated with the route lookup feature though :(
