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.
In cities and in suburbs where there are Subways, Light Rail transit and freight trains, loud train noise can occur into neighborhoods. There are even organizations against train noise such as the World Health Organization and the U.S. Environmental Protection Agency, where they have set guidelines for noise level decibel limits for Rapid Transit.
