Orlyval is a light metro shuttle service at Paris's Orly Airport using the Véhicule Automatique Léger driverless, rubber-tyred people mover technology. The line, which opened on 2 October 1991, offers free service between the two airport terminal stations, and premium fare service to Antony station, where passengers can connect to the city's RER B trains. Orlyval is the second line to use the VAL technology after the Lille Metro and the first airport people mover system to use VAL.

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.
