EMD GP40-based passenger locomotives
The passenger locomotives derivatives of the General Motors EMD GP40 diesel-electric locomotive have been, and continue to be, used by multiple passenger railroads in North America. For passenger service, the locomotives required extra components for providing steam or head-end power (HEP) for heating, lighting and electricity in passenger cars. Most of these passenger locomotives were rebuilt from older freight locomotives, while some were built as brand new models. GP40TC The GMD GP40TC was built by General Motors Diesel (GMD), for GO Transit in Toronto. Eight units were manufactured between 1966 and 1968. They were built on an enlarged frame to accommodate a head-end power generator. GO Transit sold the fleet to Amtrak in 1988, where they were based in Chicago and used on short-haul trains. In 2005, the Norfolk Southern Railway rebuilt all eight GP40TC locomotives at its Juniata Shops in Altoona, Pennsylvania. These are now classed as GP38H-3, and work as maintenance-of-way trains or standby power for Downeaster trains. GP40P Thirteen GP40Ps were built in October 1968 for the Central Railroad of New Jersey (CNJ) and paid for by the New Jersey Department of Transportation (NJDOT). The CNJ put the units in service on the Raritan Valley Line and
