The following is a list of Lima-Hamilton locomotives built between 1949 and 1951. Lima-Hamilton never gave its locomotives model numbers in the ordinary sense. L-H only used specification numbers for its diesel models.

The GE U28B diesel-electric locomotive model replaced the U25B in early 1966, featuring a slightly uprated prime mover. Early units had the same carbody styling as the U25B, while later units had design features more in common with later models. After only a year of production, this model was superseded by the U30B.
An EMD GP28 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between March 1964 and November 1965. Power was provided by an EMD 567D1 16-cylinder engine which generated 1,800 horsepower (1.34 MW). This locomotive was basically a non-turbocharged version of the EMD GP35.
The EMD GP38 is a four-axle diesel-electric locomotive built by General Motors Electro-Motive Division between January 1966 and December 1971. The locomotive's prime mover was an EMD 645 16-cylinder engine that generated 2,000 horsepower (1.49 MW). The company built 706 GP38s for North American railroads.
An EMD GP38AC is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between February 1970 and December 1971. It was basically a GP38 with an AR10 alternator instead of the GP38's normal generator.
An EMD SD38AC is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between June and October 1971. This model is an SD38 with an AR10 alternating current alternator instead of the SD38's normal direct current generator. It produces 2,000 horsepower (1,500 kW) from a 16-cylinder EMD 645E roots blown prime mover. It came equipped with or without dynamic brakes. This locomotive shares a common frame with the SD39, SD38, SD40 and SD45. The SD38AC was a transition between the SD38 and its successor, the SD38-2. 15 examples of this model were built; 6 for B&LE, 8 for DMIR and one for BC Hydro.
The EMD GP39 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between June 1969 and July 1970. The GP39 was a derivative of the GP38 equipped with a turbocharged EMD 645E3 12-cylinder engine which generated 2,300 hp (1.72 MW).
The EMD GP40-2 is a 4-axle diesel locomotive built by General Motors Electro-Motive Division as part of its Dash 2 line between April 1972 and December 1986. The locomotive's power is provided by an EMD 645E3 16-cylinder engine which generates 3,000 horsepower (2.24 MW).
The EMD SD38-2 is a model of six-axle diesel-electric locomotive built by General Motors Electro-Motive Division (EMD) from 1972 to 1979. EMD built 90 of these medium road-switchers, which were used in both yard and mainline roles. Part of the EMD Dash 2 line, the SD38-2 was an upgraded SD38 with modular electronic control systems, HT-C trucks, and many other detail improvements. The locomotive's power was provided by an EMD 16-645E 16-cylinder engine, which could generate 2,000 horsepower. These units were constructed with either 3,200 or 4,000 US gal fuel tanks and were available with or without dynamic brakes. It shared the same 64-foot-8-inch (19.71 m) frame as the SD40-2 and SD45-2, which gives it a length over couplers of 68 feet 10 inches (20.98 m).
The EMD MP15AC is a 1,120 kW (1,502 hp) diesel switcher locomotive built by General Motors' Electro-Motive Division between August 1975 and August 1984. A variant of the EMD MP15DC with an AC-DC transmission, 246 examples were built, including 25 for export to Mexico, and four built in Canada.
An EMD MP15T is a 1,500 hp 4-axle diesel switcher locomotive built by General Motors Electro-Motive Division between October 1984 and November 1987. Instead of a non-turbocharged 12-cylinder EMD 645 engine it uses a turbocharged 8-cylinder engine. The external appearance of the engine remains similar to other MP15 models.
The EMD GP15-1 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between June 1976 and March 1982. Intended to provide an alternative to the rebuilding programs that many railroads were applying to their early road switchers, it is generally employed as a yard switcher or light road switcher. This locomotive is powered by a 12-cylinder EMD 645E engine, which generates 1,500 hp (1,119 kW). The GP15-1 uses a 50-foot-9-inch (15.47 m) frame, has a wheelbase of 29 ft 9 in (9.07 m) and has a length over couplers of 54 ft 11 in (16.74 m). A total of 310 units were built for American railroads. A number of GP15-1s remain in service today for yard work and light road duty. The radiator section is similar to those found on the EMD SD40T-2 and EMD SD45T-2 "tunnel motors," leading some observers to incorrectly identify the units as such or as GP15Ts, and giving them the nickname "baby tunnel motors".
The EMD GP39-2 is a 4-axle diesel locomotive built by General Motors Electro-Motive Division between 1974 and 1984. 239 examples of this locomotive were built for American railroads. Part of the EMD Dash 2 line, the GP39-2 was an upgraded GP39. The power for this locomotive was provided by a turbocharged 12-cylinder EMD 645E3 diesel engine, which could produce 2,300 horsepower (1,720 kW).
The Century 424 was a four-axle, 2,400 hp (1,790 kW) diesel-electric locomotive. 190 were built between April 1963 and May 1967. Cataloged as a part of Alco's Century line of locomotives, the C424 was intended to replace the earlier RS-27 model and offered as a lower-priced alternative to the C425. Montreal Locomotive Works also built this locomotive as MLW Century 424.
The ALCO Century 425 was a four-axle, 2,500 hp (1,860 kW) diesel-electric locomotive. 91 were built between October 1964 and December 1966.
The ALCO Century 430 is a four-axle, 3,000 hp (2,237 kW) diesel-electric locomotive. 16 were built between July 1966 and February 1968. Cataloged as a part of ALCO's 'Century' line of locomotives, the C430 was an upgraded version of the C425 model. Since 1992, five C430s have remained in existence.
The ALCO RS-27 is a diesel-electric locomotive built by ALCO between December 1959 and October 1962. Only 27 examples were manufactured. With ALCO's introduction of the Century Series line, the C-424 replaced the RS-27 in the builder's catalog. Today, the Minnesota Commercial Railway has the only two RS-27s left in existence, both operational.
Designated as a "DL721" by ALCO, the 2,000 hp RS-32 was intended to compete with EMD's GP20 and GE's U25B locomotives. Only 35 units were produced, with 25 units ordered by New York Central in 1961 and 10 units by Southern Pacific in 1962. New York Central’s RS-32s were commonly seen in both road and local freight assignments. Southern Pacific's units were initially used in road service, but later settled into local freight service in San Francisco's "commute" territory. Here they were sometimes called upon to rescue stalled commuter trains. They later migrated across the system, ending their SP careers in Texas during the late 1970s with various other ALCo models.
The A-3170 (LS-1200) is a diesel-electric switching locomotive built between May 1950 and August 1951, by the Lima-Hamilton Corporation of Lima, Ohio, United States. Lima's original design was the A-3080, a 1,000 hp (750 kW) switcher, which became the standard for Lima's designs. A 660 hp (490 kW) switcher had also been designed at the request of American Rolling Mill Company, but none were built. By changing fuel rack settings, the A-3080 was upgraded to the A-3170 producing 1,200 horsepower (890 kW) from a turbocharged Hamilton T89SA four-stroke, eight cylinder inline diesel engine, a Westinghouse generator and 4 Westinghouse traction motors provided the 74,508 lbf of tractive effort.

The A-3080 is a 1,000 hp switcher, which became the standard for Lima's designs. By changing fuel rack settings, the A-3080 was upgraded to the A-3170, producing 1,200 horsepower from the same turbocharged Hamilton T89SA four-stroke, eight cylinder inline diesel engine, a Westinghouse generator and four Westinghouse traction motors provided the 74,508 lbf of tractive effort.
The BLH RS-12 railroad locomotive was a 1,200 hp (895 kW) diesel-electric road-switcher configured with an AAR type B-B wheel arrangement. It was the follow-on model to the former Baldwin DRS-4-4-1000, first introduced in 1948. It was more successful than its predecessor selling 50 units to eight railroads, versus 22 units to three railroads. Only one railroad, The Pennsylvania Railroad bought both models.
