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.
