Many stations are actually grouped together with common entrances and free transfers between lines and even divisions going in diverging directions. Many complexes involve use of passageways, ramps, stairways and multiple level changes to access other lines within the complex. Most complexes are patched together since the three divisions were built by competing entities and they did not want people to use their competitors.
