Train horns are used as a warning sign. Each different type of warning requires a different sequence of sound by the horn. The train horn can be used to signal things such as an upcoming intersection, upcoming train station, initiation of movement, change of direction, and warn pedestrians of the train's presence.
Traditionally, the train engineer gives horn signals. If the engineer is not present, or busy, either the co-engineeror conductor can blow the horn. Amtrak has their General Electric P42 locomotives equipped with a horn button on the engineer and conductor sides of the cab.
