GO Transit 900-911

GO Transit 900-911 were former EMD and GMDD FP7's that were rebuilt by Ontario Northland and Pacific National Corp. to provide electrical power to trains that were propelled by a locomotive that lacked the capability. In the process, they lost their engine, main generator and traction motors, and could not be used for propulsion. They also retained their operating cab and controls, and thus provided an additional control point for the train. GO Transit referred to them as Auxiliary Power-Control Units, or APCU's.

They were equipped with a General Motors 600kW 16V149-powered HEP system, and thus could provide electrical power for a 12-car train by themselves.

They were frequently used with GP40-2(W)'s 700-710 and GP40M-2's 720-726, although were also used on occasion with GP40TC's 500-507 and F40PH's 510-515. They were also required whenever GO leased their equipment to other railroads, such as to VIA Rail in the aftermath of the 1984 discovery of faulty axles and removal of all LRC equipment from service, and after the 1989 Loma Prieta earthquake in Los Angeles.
