System Testing

System testing ensures that all components of Caltrain Electrification – from the wires and power facilities to the high-performance electric trains – function seamlessly together. Learn more about the steps involved to test the different parts of the electrification infrastructure and electric trainsets on the Caltrain corridor below.

INFRASTRUCTURE
