An EMD GP40. The list of passengers locomotives on this page are derived from this locomotive.
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.
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.:55 GO Transit sold the fleet to Amtrak in 1988.:106 The units were based in Chicago and used on short-haul trains. The Norfolk Southern Railway rebuilt all eight at its Juniata Shops in Altoona, Pennsylvania during 2005. These are now classed as GP38H-3, and work as maintenance-of-way trains or standby power for Downeaster trains.
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 the North Jersey Coast Line.
The CNJ's passenger operations were transferred to NJDOT in 1976 (with Conrail operating them under contract), and in 1983 New Jersey Transit assumed operating passenger rail service in the state. Shortly after, the steam generator, which had occupied the flat end of the locomotive's long hood, was replaced with a diesel HEP generator, and the units were reclassified as GP40PH. They would later be rebuilt as GP40PH-2 units in 1991–92.
In 1987, New Jersey Transit and Metro-North ordered a set of GP40 locomotives called GP40FH-2s which were completed by Morrison Knudsen between 1987 and 1990 and combine the standard cab and frame of a GP40 with the cowl from an ex-Burlington Northern EMD F45. A total of 21 units of this type were built; 15 were delivered to New Jersey Transit, and the remaining six were for Metro-North.
As of late 2016, the Metro-North units have been rebuilt as GP40FH-2Ms, while all NJT GP40FH-2 locomotives have been retired or sold. Five units were rebuilt into MP20 switchers in 2008. Seven NJT units were purchased by Iowa Pacific Holdings and three of those were designated for use on the Hoosier State between Chicago and Indianapolis before Amtrak took over operations again on January 30, 2017.
In 1991–92, NJ Transit sent its ex-CNJ GP40PH units out for rebuilding. The units were rebuilt as GP40PH-2 locomotives.
New Jersey Transit would later order two more sets of GP40PH-2 units; these units were rebuilt from former freight GP40 units. The first order in 1993 consisted of six units rebuilt by Morrison-Knudsen are designated GP40PH-2A. The second order in 1993–94 was for 19 former Penn Central units rebuilt by Conrail. These units are classified as GP40PH-2B.
Metro-North ordered a single GP40PH-2 unit (4906); it is classified as a GP40PH-2M. It was rebuilt by Conrail in 1992.
In the late 1980s, Morrison-Knudsen rebuilt six GP40s into 12-cylinder GP39s for MARC. They were downgraded from 3,000 horsepower (2,200 kW) to 2,300 horsepower (1,700 kW), and re-equipped with 4-stroke Cummins HEP generators. As of 2015, they continue to be used by MARC for smaller train sets and work train duty.
In 1993, Morrison-Knudsen was contacted by the Maryland Transit Administration to assemble a fleet of GP40s for use on MARC. They entered service in 1994. GP40WH-2s are equipped with a Cummins head-end power generator. The Federal Railroad Administration exempted these units from the "triangular light pattern" rule because the engines were ordered with Gyralites before the mandatory use of ditch lights. All but one have been retired following the completion of an order for new MP36 locomotives. MARC only retains one GP40WH-2 (No. 68), for emergencies and track work. Several unit were leased to the MBTA for a time, but are all now out of service and later returned to MPI. CSX bought one unit for use on maintenance trains. The remaining GP40WH-2 units were rebuilt into MP32PH-Q units for SunRail.
In 1996, AMF Technotransport rebuilt six freight locomotives into passenger locomotives for the Connecticut Department of Transportation. The locomotives, designated GP40-2H, were rebuilt from ex-CSX Transportation EMD GP38s and EMD GP40s. The rebuild included an EMD 645 prime mover, producing 3,000 hp (2,200 kW), and a separate head-end power (HEP) generator.
All six units remain in Shore Line East service as of 2016. When the Hartford Line begins operations in 2018, these six units, along with all other current Shore Line East equipment, will be moved into service on that line. M8 electric multiple units will replace locomotive-hauled trains in Shore Line East service.
The Massachusetts Bay Transportation Authority currently owns and operates a set of 25 GP40 passenger diesels known as GP40MCs. They were originally built as GP40-2LWs for Canadian National in 1973–75. In 1997–98, these 25 units were very extensively rebuilt by AMF, including the addition of head-end power generators. The GP40MCs received a Top-Deck Overhaul by the Norfolk Southern Railway between 2008 and 2013, which included repair and modification to the major propulsion systems and replacement of the HEP generators. As of the fall of 2015, the GP40MC's are starting to be replaced by the MPI HSP46.
