Westinghouse Air Brake Company
Westinghouse (Westinghouse Electric, Westinghouse Air Brake Company, Canadian Westinghouse Co.) and General Electric both supplied electrical packages and brake components which were designed and built in cooperation with the ERPCC. The customer specified the equipment which was to be installed, performance was similar and most cities ordered from both suppliers. Since Westinghouse was home based near Pittsburgh, PRCo ordered 75% of its PCC fleet with Westinghouse equipment, the balance with GE. Indeed, PCCs are often identified as either Westinghouse or GE.
