The EMD GP38-2 is a four-axle diesel-electric locomotive of the road switcher type built by General Motors, Electro-Motive Division. Part of the EMD Dash 2 line, the GP38-2 was an upgraded version of the earlier GP38. Power is provided by an EMD 645E 16-cylinder engine, which generates 2000 horsepower (1.5 MW). Most built still remain in service in the modern era due to ease of maintenance and exceptional reliability.
The GP38-2 differs externally from the earlier GP38 only in minor details. Its most distinctive identifying feature is the cooling water level sight glass on the right side of the long hood. The battery box covers of the Dash 2s are bolted down instead of hinged. It can be distinguished from the contemporary GP39-2 and GP40-2 in that its Roots blown engine had two exhaust stacks, one on each side of the dynamic brake fan, if equipped, while the turbocharged GP39-2 and GP40-2 has a single stack. The GP39-2 has two radiator fans on the rear of the long hood like the GP38-2, while the GP40-2 has three. It was also available with either a high-short-hood, common on Norfolk Southern units, or a low-short-hood, which is found on most other railroads.
The GP38-2W is a Canadian variant of the GP38-2 and a forerunner of today’s wide-nose units. It is easily distinguished by its wide-nose Canadian comfort cab. 51 of these locomotives were produced for Canadian National Railways during 1973–1974.
There are snow-shields above the inertial-filter central air intakes behind the cab; the electrical boxes and equipment blower behind the cab also differ in detail from a standard GP38-2. They are otherwise identical.
The EMD F59PH series of locomotives comprises two variants of locomotives built by EMD, the original F59PH and the newer F59PHI. These modern Diesel-electric locomotives are popular among North American commuter rail services.
The F59PH was the first in the “F59” Series of locomotives. Eighty-three locomotives were built from May 1988 to May 1994 for two commuter transit railroads, Metrolink of Los Angeles, California, USA and GO Transit of Toronto, Ontario, Canada. While Metrolink continues to use these locomotives today, in 2008, GO Transit began discontinuing operations using this locomotive in favour of the new MPI MP40PH-3C.:159 Only eight locomotives that were refurbished in 2011 remain in service.
This locomotive is equipped with a turbocharged EMD 12-710G3A, a 12 cylinder, two-stroke Diesel engine (prime mover), front and rear platforms, a full-width cab with a three-piece windshield. Earlier EMD cowl-type locomotives had used a two-piece windshield, while the Canadian comfort cab used a four-piece design.:159
The F59PH is still used today, mainly on commuter railroads:
GO Transit, Toronto, Ontario
Metrolink, Los Angeles, California
NCDOT, North Carolina on Amtrak Piedmont service.
Trinity Railway Express, Dallas-Fort Worth, Texas
Operator Number Year built Unit numbers Comments
GO Transit 8 1988–1994 557–564
GO Transit owned 49 locomotives (520–568), but most have been retired and replaced by new MPI MP40 locomotives.
Units refurbished in 2011 remain in service.
Metrolink 23 1992–1993 851–873
855 destroyed in the 2008 Chatsworth train collision and retired or scrapped.
3 units leased from GO Transit.
NCDOT 4 1810, 1859, 1869, 1893
Used on Amtrak Piedmont service.
Purchased secondhand from GO Transit and rebuilt by American Motive Power.
Trinity Railway Express 8 1988–1994 525, 527, 528, 565–568
Purchased secondhand from GO Transit.
RB Railway Group 12 1988-1990 18520–18524, 18531, 18537–18538, 18547, 18551, 18554
Purchased secondhand from GO Transit.
Company leases units to commuter operators. Currently units 18520, 18522 & 18533 are leased to Metrolink, to replace engines out of service for installation of positive train control equipment. Some units are scheduled to be used on the proposed SEMCOG Commuter Rail.
The EMD F59PHI is a common diesel-electric locomotive on passenger trains in North America, built originally by General Motors Electro-Motive Division (EMD), now built by the successor company, Electro-Motive Diesel, which is owned by Progress Rail Services, itself a division of Caterpillar.
First built in 1994, the locomotive is a 3,200 hp (2.4 MW) B-B diesel-electric locomotive intended for service on North American mainlines. This locomotive is equipped with a turbocharged EMD 12-710G3C-EC, a 12 cylinder, 2 stroke diesel engine (prime mover). The main (traction) alternator converts mechanical energy from the prime mover into electrical energy that is distributed through a high voltage cabinet to direct current traction motors. Each of the four traction motors is directly geared to a pair of driving wheels. The gear ratio of the traction motors (model D87BTR) to wheel axle determines the maximum operating speed of the locomotive; a standard F59PHI has a gear ratio of 56:21 which provides a top speed of 110 miles per hour (180 km/h).
The F59PHI has a fully enclosed carbody which provides protected walkways for easy access to the engine room and trailing units. This arrangement allows routine maintenance while the locomotive is in service. The noteworthy aspect of this locomotive’s exterior is the use of composites to present a streamlined appearance.
