Train noise

From Wikipedia, the free encyclopedia

Train noise is sound produced by vehicles using a trackbed or rail guidance system. Trains include freight, long haul passenger, commuter rail, metro or mass transit and light rail systems.

• Train noise can be a type of environmental noise. When a train is moving, there are several distinct sounds such as the locomotive engine noise and the wheels turning on the railroad track. The air displacement of a train or subway car in a tunnel can create different whooshing sounds.
• Trains also employ horns, whistles, bells, and other noisemaking devices for both communication and warning.
