The U25C is a diesel locomotive built by General Electric intended for the United States domestic market. Launched in September 1963, it remained in production until December 1965. It was replaced by the U28C.
The U28C locomotive was developed by General Electric from the U25C, with a slight increase in power of 300 hp (224 kW). A passenger-hauling variant, the U28CG, was also produced for the Atchison, Topeka and Santa Fe Railway.
The GE U30C is a six-axle locomotive built by General Electric from 1966 to 1976. With 600 units sold, the U30C proved to be a viable alternative for customers who were unable to purchase SD40s from Electro-Motive Diesel (EMD) due to production backlog. Throughout its ten-year production span, the U30C was known for reliability issues concerning its electrical system. However, most railroads were assured of the reliability of the GE Model 752 DC traction motor, and began to place orders for U30Cs starting in 1966. When production ended, the last U30Cs carried pre-Dash 7 specifications, which would be carried in its replacement, the GE C30-7.
The EMD SD40-2 is a 3,000-horsepower (2,200 kW) C-C diesel-electric locomotive built by EMD from 1972 to 1989.
The Evolution Series is a line of diesel locomotives built by GE Transportation Systems, initially designed to meet the U.S. EPA's Tier 2 locomotive emissions standards that took effect in 2005. The first pre-production units were built in 2003. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference. All are powered by the GE GEVO engine.
The GE U23B was a 2,250 horsepower diesel-electric locomotive built by GE Transportation from 1968 to 1977. It was one of the most successful models of the Universal Series, with 481 units built, including 16 exported to Peru. The U23B was replaced by the B23-7.
The C30-7 is a 6-axle diesel-electric locomotive built by GE Transportation Systems between September 1976 and May 1986 as an updated U30C with a 16-cylinder 3,000 horsepower (2,200 kW) FDL-series diesel engine. 1,137 were built for North American railroads.
The U34CH was a 3,600 hp (2,700 kW) passenger diesel locomotive built by General Electric between 1970 and 1973. In total, 33 U34CH units were built; 32 were built for the New Jersey Department of Transportation and operated by the Erie Lackawanna Railway and, later, Conrail, with the last unit coming as a later rebuild of a GE U30C for the New York MTA.
The GE P30CH was one of the first brand-new diesel-electric locomotives built for Amtrak by General Electric during Amtrak's early years. The design was based on the GE U30C, but had a cowl carbody like its EMD competitors. Amtrak operated them between 1975 and 1992.
The GE U36C is a 3600 hp diesel-electric locomotive model built by GE Transportation Systems.
The GE U30CG was a passenger-hauling diesel-electric locomotive built by GE Transportation Systems. It was a passenger variant of GE's U30C design purchased by the Atchison, Topeka and Santa Fe Railway. ATSF had purchased ten U28CG locomotives in 1966, and while these locomotives were satisfactory operationally, the railroad felt that their utilitarian appearance was unsuitable for its passenger trains. Desiring smooth-sided passenger power, the railroad ordered the first cowl units from both GE and GM-EMD. GE produced the U30CG to meet this requirement. It was mechanically identical to a U30C except that the bodywork was replaced with a full-width long hood with fluted stainless-steel panels, and a full-width rounded nose and slanted cab front were fitted.
The GE Universal Series is a series of diesel locomotives intended for the export market introduced by General Electric in early 1956. General Electric had previously partnered with Alco, producing locomotives for export using Alco’s 244 engine, and provided electrical parts for Alco’s domestic production. However, with the advent of the Universal Series, GE ended its partnership with Alco and entered the export locomotive market on its own.
The South African Railways Class 33-000 of 1965 was a diesel-electric locomotive.
The South African Railways Class 33-400 of 1968 was a South African and Namibian diesel-electric locomotive.
The South African Railways Class 34-000 of 1971 is a diesel-electric locomotive.
The South African Railways Class 34-500 of 1974 is a diesel-electric locomotive.
The South African Railways Class 35-200 of 1974 is a diesel-electric locomotive.
The GE U26C diesel locomotive model was introduced by GE Transportation Systems in 1971. All examples of this model are six axle units, and have the wheel arrangement C-C or Co'Co'.
The Dash 7 Series is a line of diesel-electric freight locomotives built by GE Transportation. It replaced the Universal Series in the mid-1970s, and was superseded by the Dash 8 Series in the mid-1980s.
The Dash 8 Series is a line of diesel-electric freight locomotives built by GE Transportation. It replaced the Dash 7 Series in the mid-1980s, and was superseded by the Dash 9 Series for freight usage and the Genesis Series for passenger usage in the mid-1990s.
