Several distinct sounds are created by various parts of the train, such as engines, traction motors, brakes, and the wheels rolling on the rails. Roughness and irregularities on the wheel and rail surfaces are a source of noise and vibration. Rail joints and squats on the rail cause a familiar "clickety-clack" sound as train wheels roll over them.
Spectrogram of the train sound. The Sea Train is the name given to a sound recorded on March 5, 1997, on the Equatorial Pacific Ocean autonomous hydrophone array. The sound rises to a quasi-steady frequency. According to the NOAA, the origin of the sound is most likely generated by a very large iceberg grounded in the Ross Sea, near Cape Adare. [10
To maximize sound output, Transport Canada requires that all train horns be mounted facing the direction of travel, near the front of the roof, no further than 1.5 metres (4 ft 11 in) behind the rear of the cab, and near the centerline of the locomotive in a location where it will not obstruct exhaust pipes in any direction.

The driver uses the horn to warn others of the vehicle's presence or approach, or to call attention to some hazard.
Depending on the upcoming signal state, the AWS will either produce a 'horn' sound (as a warning indication), or a 'bell' sound (as a clear indication). If the train driver fails to acknowledge a warning indication, an emergency brake application is initiated by the AWS; if the driver correctly acknowledges the warning indication, by pressing ...
