Train noise is vehicle noise created by trains. Noises may be heard inside the train and outside. Various parts of a train produce noise, and different kinds of train wheels produce different amounts of noise. Noise barriers can attenuate the noise.
Sources
- 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.
- Trains propelled by electric traction motors controlled by high speed electronic inverters can produce a whining noise.
