32km narrow gauge(1000mm), electrified at 15kV 16.7Hz
This company is one of the few narrow gauge railways electrified at high voltage AC. They operate trains on Morges-Apples-Bière/l'Isle-Mont-la-Ville. Recently (1997) a new 2km branch line to an army base was opened. Tanks on standard gauge cars are the most important freight traffic on the line.
In 2003 the name of the company was officially changed into MBC (Transports de la région Morges-Bière-Cossonay) but BAM was retained as a brand for the railway operations.
