Breakers: Difference between revisions

Revision as of 14:43, 11 March 2025

Breakers are switches that isolate and protect separate electrical systems on motorized rail vehicles . Breakers are typically present on post-steam era rolling stock, and allow each of these electrical systems to be toggled on and off, individually. There are a few types electrical systems:

Starter – This breaker enables ignition of internal combustion engines .

Electrics – This breaker enables accessories that run on electricity, such as compressors , lights and wipers . On steam locomotives, the equivalent of this breaker is the dynamo valve.

Traction Motors (TM) – This breaker enables traction motors on vehicles with electric powertrains . In case of overheating , traction motors can trip the breaker, which then needs to be manually re-enabled.
