The Baldwin Locomotive Works (BLW) was an American manufacturer of railroad locomotives from 1825 to 1951. Originally located in Philadelphia, it moved to nearby Eddystone, Pennsylvania, in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete as demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation.
Lima Locomotive Works was an American firm that manufactured railroad locomotives from the 1870s through the 1950s. The company took the most distinctive part of its name from its main shop's location in Lima, Ohio. The shops were located between the Erie Railroad main line, the Baltimore & Ohio's Cincinnati-Toledo main line and the Nickel Plate Road main line and shops.
Progress Rail Locomotives, doing business as Electro-Motive Diesel (EMD), is an American manufacturer of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. The company is owned by Caterpillar through its subsidiary Progress Rail.
The BLH S12 was a 1,200-horsepower (890 kW) diesel-electric locomotive intended for use in yard switching. Utilizing a turbocharged 6-cylinder version of the powerful 606A diesel prime mover, S12s were known for their "lugging" power, despite being temperamental. Like most BLH switchers, the S12 had AAR Type-A switcher trucks in a B-B wheel arrangement. 451 units were built between 1951 and 1956, when BLH left the locomotive market.
The BLH AS-416 was a diesel-electric locomotive of the road switcher type rated at 1,625 hp (1,212 kW), that rode on three-axle trucks, having an A1A-A1A wheel arrangement.
The BLH AS-616 was a 1,600 horsepower (1,200 kW) C-C diesel-electric locomotive built by Baldwin-Lima-Hamilton between 1950 and 1954. Nineteen railroads bought 214 locomotives, and two railroads bought seven cabless B units. The AS-616 was valued for its extremely high tractive effort, far more than any comparable ALCo or EMD product. It was used in much the same manner as its four-axle counterpart, the AS-16, and its six-axle sister, the AS-416, though the six-traction motor design allowed better tractive effort at lower speeds.
The BLH AS-16 was a diesel-electric locomotive rated at 1,625 hp (1,212 kW), that rode on two-axle trucks, having a B-B wheel arrangement. It was the successor to Baldwin's DRS-4-4-1500 model, and remained in production until Baldwin-Lima-Hamilton quit the locomotive manufacturing business in 1956.
The BLH S8 was an 875-horsepower (652 kW) diesel-electric locomotive intended for use in yard switching. The Baldwin-Lima-Hamilton Corporation produced a total of 63 units between 1951 and 1953. Of these, nine were "calf" units built for Oliver Iron Mining Company in Minnesota. A tenth calf had been built for them on order, but when delivery was refused, it was fitted with a cab, and converted to a regular S8.
The BLH RF-16 was a 1,625-horsepower (1,212 kW) cab unit-type diesel locomotive built for freight service by the Baldwin-Lima-Hamilton Corporation between 1950 and 1953. All RF-16s were configured with a B-B wheel arrangement and ran on two AAR Type B two-axle road trucks, with all axles powered. A total of 109 cab-equipped A units were built, along with 51 cabless booster B units, for a total of 160 locomotives built. As was the case with most passenger locomotives of its day, the RF-16s came equipped with a retractable, nose-mounted drop coupler pilot. Unlike competing units from EMD and Alco, the RF-16 used an air-powered throttle, meaning that it could not be run in MU operation with EMD or Alco diesels without special MU equipment.
The firm of Hooven, Owens, Rentschler, and Company manufactured steam and diesel engines in Hamilton, Ohio. Because the firm was frequently known by its initials, H.O.R., the Hooven is sometimes incorrectly rendered as Hoover, and the Owens may be mistaken for Owen.
The Baldwin DT-6-6-2000 was a twin-engined diesel-electric transfer switcher, built by Baldwin Locomotive Works between 1946 and 1950.
The A-3149 (LS-750) and A-3171 (LS-800) were diesel-electric switching locomotives built between November 1949 and June 1951, by the Lima-Hamilton Corporation of Lima, Ohio, U.S.A.. The A-3149 is a 750 horsepower (560 kW) switcher. It was later upgraded to 800 hp (600 kW) by changing fuel rack settings. Both models used the same turbocharged Hamilton T69SA four-stroke, six cylinder inline diesel engine, a Westinghouse generator and 4 Westinghouse traction motors.
The A-3174 (LRS-1200) was a model of 1,200 hp B-B diesel locomotive built by Lima-Hamilton in 1950. All sixteen units were built for the New York Central. A second order of 17 was outstanding at the time of Lima-Hamilton's merger with the Baldwin Locomotive Works, but owing to insufficient time to build the locomotives before the locomotive production ceased at Lima, NYC agreed to receive RS-12s from BLH, they were built at Eddystone, PA.
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 (LS-1000) is a diesel-electric switching locomotive built between May 1949 and April 1950, by the Lima-Hamilton Corporation of Lima, Ohio, United States. 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.
The BLH RT-624 was a twin-engined diesel-electric locomotive, built by Baldwin-Lima-Hamilton Corporation between August 1951 and February 1954.
The RP-210 was a streamlined 1,000 hp (750 kW) locomotive built in 1956 by Baldwin-Lima-Hamilton, specifically to operate with the experimental, all-aluminum Train-X coaches that the Pullman-Standard Car Manufacturing Company built. The model represented Baldwin's attempted entry into the lightweight passenger locomotive market, but only three of the low-slung diesel-hydraulic units were produced. The first was built for the New York Central Railroad to power their Ohio Xplorer train between Cleveland, Columbus, and Cincinnati, and a pair was purchased by the New York, New Haven and Hartford Railroad to double-end their Dan'l Webster, running between New York City and Boston.
The Dan'l Webster was a named train of the New York, New Haven and Hartford Railroad that traveled between Grand Central Terminal, New York, New York, and South Station, Boston, Massachusetts. The Dan'l Webster was an attempt by the New Haven to modernize rail travel and lure people out of their cars.
A transfer switcher was a type of railroad locomotive specifically designed to perform "transfer" work in which freight cars are transported between two freight yards in a large terminal area.
