Medium-capacity rail system
A medium-capacity system (MCS), also known as light rapid transit or light metro, is a rail transport system with a capacity greater than light rail, but less than typical heavy-rail rapid transit. MCS's trains are usually 1–4 cars. Most medium-capacity rail systems are automated or use light rail type vehicles.
