The device converts the irregular up-and-down vibration of a train track to a unidirectional rotation of a generator. The concept is similar to other energy-harvesting devices such as the speed bump.

Rail power generated by passing trains could save more than $10 million
A way to harvest energy from vibrations generated by passing trains could save more than $10 million in trackside power costs and reduce carbon dioxide emissions by 3,000 tons in New York alone, says its inventor, Stony Brook University professor Lei Zuo.
