The EU standards make a distinction between a station, and a Stop. Technically there should often be two Stop Points (or platforms) for the tram, or either side of the track and a 'station' for the group. In some cases there may indeed be one platform in the middle of the tram service with tracks on either side in which case only one stop point would be defined. Similarly an metro station may have one 'station' but multiple platforms. It would make sense to rationalise bus stops, tram stops, metro platforms, ferry quays into the same structures as the standards do. > > > The remaining issue revolves around the direction of the bus at a > > particular node.

Lets sort out fixed infrastructure and then revisit timetable.
