Compressor: Difference between revisions

Revision as of 14:51, 11 March 2025

Most motorized rail vehicles come equipped with compressors that can pump air for the air brake system , and sometimes other systems too. Compressors are typically powered by electricity , but on steam engines they are steam-powered.

Compressors activate when main reservoirs drop under 7 bar , and deactivate when the reservoirs are full, usually at 8 bar .

Compressors sometimes produce spitting sounds, when powering on or off. They do this to clear air lines of potential moisture.

On vehicles with a diesel generator , compressor power can be increased by revving the engine into higher RPM, while the reverser is at a neutral setting.

Before setting a vehicle in motion, make sure that the compressor is operational, either via breakers or valves. Compressors can fail if a vehicle is sufficiently damaged .
