How do light rails get electricity?

While the third rail on subway track is installed in a protected environment inside the subway tunnel, light rail can be subject to weather. Light-rail cars are linked to the power source via catenary wires installed overhead 12 to 16 feet above ground.

Freight and passenger rail rely almost exclusively on diesel power. The latest diesel innovations contribute to cleaner air and reaching climate goals. According to the Association of American Railroads, in a typical year, US freight railroads move around 1.7 billion tons across nearly 140,000-miles of track.
