The P-series horns have longer bells and a heavier manifold than the M-series. [3] The name of the horn is a P followed by the bells that face forward, followed by R if any are reversed, and then the numbers of the reversed bells; a P12345 is a true five-chime horn with all bells facing forward, while P135R24 has bells 2 and 4 reversed.

Diagram of a typical locomotive air horn power chamber, showing operation. Train horns are operated by compressed air, typically 125–140 psi (8.6–9.7 bar), and fed from a locomotive main air reservoir. When the engineer opens the horn valve, air flows through a supply line into the power chamber at the horn's base (diagram, right).
Short velocity stacks on a 302 cu.in. Ford FE engine in the tight confines of a Ford GT-40. A velocity stack, trumpet, or air horn [1] is a typically flared, parallel-sided tubular device fitted individually or in groupings to the entry of an engine's air intake system to smooth high speed airflow, and allow engine intake track tuning to incorporate pressure pulses created by its internal ...
An air horn consists of a flaring metal or plastic horn or trumpet (called the "bell") attached to a small air chamber containing a metal reed or diaphragm in the throat of the horn. Compressed air flows from an inlet line through a narrow opening past the reed or diaphragm, causing it to vibrate, which creates sound waves. The flaring horn ...
Leslie-Tyfon horns became the standard on most American railroads. [5] Leslie's horns were the most popular locomotive horns, and the standard for GM Electro-Motive Division models. Later, Leslie introduced the Type S Supertyfon, with three- and five-chime versions. The three-chime S3L was B, D#, A. Leslie sold more horns than competitor Nathan ...

The sound of the flugelhorn has been described as halfway between a trumpet and a French horn, whereas the cornet's sound is halfway between a trumpet and a flugelhorn. [6] The flugelhorn is as agile as the cornet but more difficult to control in the high register (from approximately written G 5 ), where in general it locks onto notes less easily.
It was basically a small coal-fired hot air engine, which compressed air in a cylinder on top of which was a reed horn. The Daboll trumpet, consists of a steel reed vibrating within a horn, which uses the hot air engine to force cold air by means of an air pump into a boiler, from which it escapes into the horn through a valve, causing the ...
