The B 81500 (often called BGC) is a class of bi-mode multiple units built by Bombardier for SNCF and used on the TER network in France.

They feature air-conditioning, comfortable seating, and are equipped with power outlets and onboard passenger information systems.

They are designed to be accessible to passengers with reduced mobility, with features such as wheelchair ramps and audio announcements.

The trains are capable of operating on diesel power as well as a 1.5 kV DC electricity supply, and have a top speed of 160 km/h (99 mph).

They are widely used in the French railway network and have been a key element in the modernization of the suburban and regional services in France.
