The Rapid Transit Database (RTDB) presents all publically available data about every rapid transit line in the world. ITDP maintains the RTDB and updates it annually. You can view or download the full database here.
Rapid transit is the backbone of public transportation, especially in large cities, because it allows people to travel quickly between different neighborhoods. It functions best as part of a larger urban mobility system that includes walking and cycling.
