This stainless steel interurban car’s electrical system was designed for both reliability and redundancy. The batteries in the open compartment were responsible for powering emergency lighting, communication systems, and other essential functions when the train was not drawing power from overhead lines. These would be kept charged by the generator, visible in the center of the image, which converted mechanical energy into electrical current.
To the left of the generator, the large bank of traction motor resistors can be seen. These played a crucial role in controlling the train’s acceleration and braking, dissipating excess electrical energy as heat when the motors were not under full load. This system allowed for smoother speed regulation and reduced wear on mechanical components.
Together, these components formed an integral part of the train’s electrical and propulsion system, ensuring a stable power supply and efficient operation over long distances. Though now dormant, the engineering behind them speaks to a time when robust, serviceable designs kept the rail network moving.
