Breakers

The more recent motorized rail vehicles are equipped with breakers, to isolate and protect the separate electrical systems onboard. These systems, such as the Starter, Electrics and Traction Motors, can be toggled by breaker switches.

Starter – Enables engine ignition (only present on vehicles with internal combustion engines)

Electrics – Enables the electrical systems, such as the compressor, lights and wipers.

Traction Motors (TM) – Enables the traction motors (only present on vehicles with an electric powertrain).
