HMA INSTRUMENTATION supplies Locomotive Air Horns mainly for rail and marine applications. These are available in various materials and varying notes, thereby meeting most tone and velocity requirements, especially when used as locomotive horns.

The Locomotive Air Horns from HMA INSTRUMENTATION may also be connected to carbon dioxide or nitrogen cylinders when an air supply is not available – for example, when used as a fire alarm in public buildings, or wide-area alarms on mine sites.
