Throughout the history

of locomotive airhorns

there have been four major players

in the airhorn business:

Nathan, Leslie, Westinghouse and Prime.

From the early days of

Westinghouse single notes on locomotives

to today’s Nathan K5LA Airchime five chimes,

there have been several horns

that have come and gone.

Due to changes in production,

i.e. different kinds of metal

used in production,

or changes is the castings being used,

a locomotive airhorn can change

its tune, pitch or sound

drastically from one to another.
