The EMD GP9E and GP9R are rebuilds from EMD GP9 diesel locomotives that were built by General-Motors Electro-Motive Division for the St. Louis Southwestern Railway (also known as the "Cotton Belt Route") and the Southern Pacific Transportation Company. [1] [2] [3]
Beginning in 1970 with SP GP9 #3424, all of the pre-existing EMD GP9 diesel locomotives that were on the St. Louis Southwestern Railway (also known as the "Cotton Belt Route") and Southern Pacific's roster were rebuilt into GP9E's and GP9R's with the number series beginning at #3300. [1] [2] [3]
Because of the internal differences of the three 'Phases', different 'rebuild' schemes were required, which meant that they were placed into different number series. As well some got Farr air filter boxes behind the cab of the units. [1]
As the rebuilds had came and went, alongside the un-rebuilt units, no numbers were reused from the Southern Pacific's 1965 renumbering scheme. [1]
The Southern Pacific Transportation Company began rebuilding their units in 1970, while the St. Louis Southwestern Railway (also known as the "Cotton Belt Route") began rebuilding their units in 1974. [1]
Nine of Southern Pacific's GP9E/GP9R locomotives were painted into the Southern Pacific's "Kodachrome" livery of the Failed merger between Southern Pacific and Santa Fe, these units were GP9E/R locomotives #2873, #3370, #3735, #3739, #3775, #3778, #3784, #3792 and #3846. [1]
Out of all the 283 units that were rebuilt, six EMD GP9R locomotives have survived into preservation:
The Southern Pacific was an American Class I railroad network that existed from 1865 to 1996 and operated largely in the Western United States. The system was operated by various companies under the names Southern Pacific Railroad, Southern Pacific Company and Southern Pacific Transportation Company.
The Santa Fe–Southern Pacific merger was an attempted corporate consolidation of two of the major railroads in the Western United States at the time: the Atchison, Topeka and Santa Fe Railway and the Southern Pacific Railroad. The approximately US$5 billion deal was announced in September 1983 and in December 1983, both companies were acquired by a new holding company, the Santa Fe Southern Pacific Corporation and both companies' extensive non-railroad related assets were immediately combined. However, the Southern Pacific Railroad remained in a voting trust and the railroads continued to be operated independently and competitively while the merger worked through the regulatory process.
The EMD DDA40X is a 6,600 hp (4,943 kW) D-D locomotive, built by EMD from 1969 to 1971 exclusively for the Union Pacific Railroad. It is the most powerful diesel-electric locomotive model ever built on a single frame, having two 16-645E3A diesel prime movers. Union Pacific has marked DD40X on the cab exteriors, while EMD literature inconsistently refers to this model as either DD-40X or DDA40X.
The EMD SW1 is a 600-horsepower (450 kW) diesel-electric switcher locomotive built by General Motors' Electro-Motive Corporation between December 1938 and November 1953. Final assembly was at EMD's plant at LaGrange (McCook) Illinois. The SW1 was the second generation of 3,402 cu in (55.75 L) switcher from EMD, succeeding the SC and SW. The most significant change from those earlier models was the use of an engine of EMD's own design, the then-new 567 engine, here in 600 hp (450 kW) V6 form. 661 locomotives of this design were built, with a gap in production between March 1943 and September 1945 due to World War II.
The EMD GP7 is a four-axle (B-B) diesel-electric locomotive built by General Motors Electro-Motive Division and General Motors Diesel between October 1949 and May 1954.
The EMD GP9 is a four-axle diesel-electric locomotive built by General Motors' Electro-Motive Division between 1954 and 1959. The GP9 succeeded the GP7 as the second model of EMD's General Purpose (GP) line, incorporating a new sixteen-cylinder engine which generated 1,750 horsepower (1.30 MW). This locomotive type was offered both with and without control cabs; locomotives built without control cabs were called GP9B locomotives.
An EMD GP20 is a 4-axle diesel-electric locomotive built by General Motors' Electro-Motive Division between November 1959 and April 1962. Power was provided by an EMD 567D2 16-cylinder turbocharged engine which generated 2,000 horsepower (1,500 kW). EMD was initially hesitant to turbocharge their 567-series diesel engine, but was spurred on to do so following successful tests made by Union Pacific in the form of UP's experimental Omaha GP20 units. 260 examples of EMD's production locomotive model were built for American railroads.
The SD7 is a model of 6-axle diesel locomotive built by General Motors Electro-Motive Division between May 1951 and November 1953. It had an EMD 567B 16-cylinder engine producing 1,500 horsepower (1.12 MW) for its six traction motors. United States railroads bought 188 units.
The EMD SD9 is a model of diesel locomotive built by General Motors Electro-Motive Division between January 1954 and June 1959. An EMD 567C 16-cylinder engine generated 1,750 horsepower (1.30 MW). Externally similar to its predecessor, the SD7, the SD9 was built with the improved and much more maintainable 567C engine.
The SD45 is a six-axle diesel-electric locomotive class built by General Motors Electro-Motive Division between 1965 and 1971. It has an EMD 645E3 twenty-cylinder engine generating 3,600 hp (2,680 kW) on the same frame as the SD38, SD39, SD40, and SDP40. As of 2023, most SD45s have been retired, scrapped or rebuilt to SD40-2 standards.
The Western Pacific Railroad Museum (WPRM) in Portola, California, known as the Portola Railroad Museum until January 1, 2006, is a heritage railroad and archives that preserves and operates historic American railroad equipment and preserves documents, photos and information. The museum's mission is to preserve the history of the Western Pacific Railroad and is operated by the Feather River Rail Society, founded in 1983. It is located at a former Western Pacific locomotive facility, adjacent to the Union Pacific's former Western Pacific mainline through the Feather River Canyon.
The EMD GP16 are a series of rebuilt diesel-electric locomotives, a result of a remanufacturing program initiated by the Seaboard Coast Line Railroad (SCL) in an effort to spare the cost of purchasing new motive power in the late 1970s. This involved the rebuilding of their aging fleet of EMD GP7, GP9 and GP18 road switchers. 155 locomotives were rebuilt by the SCL.
Southern Pacific Railroad (SP) number 1518 is an EMD SD7, and was the first ever SD series diesel locomotive, originally built in May 1951 as General Motors Electro-Motive Division's (EMD) prototype Demonstrator #990.
Union Station, also known as Ogden Union Station, is a train station in Ogden, Utah, United States, at the west end of Historic 25th Street, just south of the Ogden Central Station. Formerly the junction of the Union Pacific(UP) and Central Pacific (CP) railroads, its name reflects the common appellation of train stations whose tracks and facilities are shared by railway companies.
The EMD GP10 is a diesel-electric locomotive that is the result of rebuilding a GP7, GP9 or GP18.
The Krauss-Maffei ML 4000 is a road switcher diesel-hydraulic locomotive, built between 1961 and 1969 by German manufacturer Krauss-Maffei in Munich, Germany. It generated 3,540 horsepower (2,640 kW) from two Maybach V16 engines. 37 examples were built for two North American railroads and one South American railroad.
The Utah Central Railway is a shortline railroad serving Ogden, Utah and surrounding areas. It interchanges with the Union Pacific Railroad (UP), as well as with BNSF Railway trains running over the UP via trackage rights. The company began operations in 1992 as a private switching railroad, and became a common carrier in 1995. It expanded operations in 2001 and 2004, and the Patriot Rail Corporation gained control in January 2008.
The EMD SD45R was a rebuild from EMD SD45 diesel locomotives that were originally built between August 1966 and January 1970 for the Southern Pacific Transportation Company, but were rebuilt by the Southern Pacific themselves under the Southern Pacific's M-99 rebuild program between 1979 and 1985.
The EMD SD9E was a rebuild from EMD SD9 diesel locomotives that were built by General-Motors Electro-Motive Division for the Southern Pacific Transportation Company.
The EMD SD7R was a rebuild from EMD SD7 diesel locomotives that were built by General-Motors Electro-Motive Division for the Southern Pacific Transportation Company.
