ABSTRACT:
A solar-powered, electric railroad switch stand includes a housing having a mounting mechanism for mounting a solar cell assembly for converting solar energy into electrical current, a storage battery, and a motor connected to a gear reduction mechanism having an output shaft extending therefrom. The battery stores a charge from the electrical current of the solar cells and is electrically coupled to the motor to drive a gear reduction mechanism. An operating device is linked to the output shaft and is operable to move the switching rails.
