Crews recently installed the first Traction Power Substation (TPSS) on the project. The TPSS converts AC power from the local utility into DC power that then travels through the overhead wires to power the light rail system. Overall, eight TPSS units will be installed from Glendora to Pomona – each about a mile apart.
