The SD20-2 was a type of road switcher diesel-electric locomotive created in 1979/1980 by the Baltimore and Ohio Railroad by rebuilding EMD SD35 locomotives. [1] Five of the B&O's SD35 fleet were rebuilt at their Cumberland Yard by fitting a non-turbocharged EMD 645 engine and upgraded electrical systems. [2] They were placed in service at the B&O Queensgate Yard in Cincinnati, Ohio attached to slugs, engineless units with traction motors that draw their power from the "mother" unit.

Road switcher

A road switcher is a type of railroad locomotive designed to both haul railcars in mainline service and shunt them in railroad yards. Both type and term are North American in origin, although similar types have been used elsewhere.

Baltimore and Ohio Railroad former rail system in the United States of America

The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States, with its first section opening in 1830. It came into being mostly because the city of Baltimore wanted to compete with the newly constructed Erie Canal and another canal being proposed by Pennsylvania, which would have connected Philadelphia and Pittsburgh. At first this railroad was located entirely in the state of Maryland, with an original line built from the port of Baltimore west to Sandy Hook.

EMD SD35 model of 2500 hp Co′Co′ American diesel locomotive

An EMD SD35 is a 6-axle road switcher diesel-electric locomotive built by General Motors Electro-Motive Division between June 1964 and January 1966. Power was provided by an EMD 567D3A 16-cylinder engine which generated 2,500 brake horsepower (1,900 kW). A 3,000-US-gallon fuel tank was used on this unit. This locomotive model shared a common frame with the EMD SD28, giving it an overall length of 60 feet 8 1⁄2 inches (18.504 m). 360 examples of this locomotive model were built for American railroads.

With the B&O, the SD20-2s were numbered #7700–7704. At some point, #7700 and #7702 swapped numbers. All of them passed to CSX Transportation as #2400-2404, but are now withdrawn from CSX service. One of the units, #2401, went on to the Ohio Central Railroad System; #2401 was in turn resold to the Pacific Harbor Line and reassigned road #45 (pictured at right). #2404 was scrapped by Cycle Systems of Roanoke, Virginia in August 2006.

EMD SD80MAC

The SD80MAC is a 5,000 horsepower (3.7 MW) C-C roadswitcher diesel-electric locomotive. The model uses a 20-cylinder version of EMD's 710G prime mover, and is the first diesel locomotive to use a 20-cylinder engine since EMD's SD45 and SD45-2. It introduced a wide radiator housing similar to GE Transportation locomotives and the placement of dynamic brakes at the rear of the locomotive, which is a quieter location, features that were incorporated into the SD90MAC and SD70ACe models. Key spotting difference between the SD80MAC and SD90MAC include no external rear sandbox on the SD90MAC, rear number boards, and the placement of the front numberboards. The SD80MAC also has recessed red marker lights in the nose, an identifying feature unique to Conrail locomotives, although Norfolk Southern (NS) has removed the lights on most of their former Conrail engines.

The EMD GP30 is a 2,250 hp (1,680 kW) four-axle road switcher diesel-electric locomotive built by General Motors Electro-Motive Division of La Grange, Illinois between July 1961 and November 1963. A total of 948 units were built for railroads in the United States and Canada, including 40 cabless B units for the Union Pacific Railroad.

EMD DDA40X model of 47 American 6600hp Do′Do′ diesel-electric locomotives

The DDA40X is a 6,600 horsepower D-D experimental roadswitcher diesel-electric built by the General Motors EMD division of La Grange, Illinois for the Union Pacific Railroad. Nicknamed "Centennials" because they were built around the 100th anniversary of the completion of the First Transcontinental Railroad, and "Big Jack", the DDA40X uses two diesel engine prime movers, each rated at 3,300 horsepower.

B unit diesel or electric locomotive without a cab (c.f. “A unit”)

A B unit, in railroad terminology, is a locomotive unit which does not have a driving cab or crew compartment, and must therefore be controlled from another, coupled locomotive with a driving cab. The terms booster unit and cabless are also used. The concept is largely confined to North America. Elsewhere, locomotives without driving cabs are rare.

EMD SD90MAC model of American diesel locomotive

The EMD SD90MAC is a 6,000 hp (4,470 kW) C-C roadswitcher diesel-electriclocomotive produced by General Motors Electro-Motive Division. It is, with the SD80MAC, one of the largest single-engined locomotives produced by that company, surpassed only by the dual-engined DDA40X.

EMD SW1

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, no SW1s were built after March 1943 until production started again in September 1945.

EMD GP7 model of 1500 hp North American diesel locomotive

The EMD GP7 is a four-axle (B-B) road switcher diesel-electric locomotive built by General Motors Electro-Motive Division and General Motors Diesel between October 1949 and May 1954. Power was provided by an EMD 567B 16-cylinder engine which generated 1,500 horsepower (1,119 kW). The GP7 was offered both with and without control cabs, and those built without control cabs were called a GP7B. Five GP7B's were built between March and April 1953. The GP7 was the first EMD road locomotive to use a hood unit design instead of a car-body design. This proved to be more efficient than the car body design as the hood unit cost less to build, was cheaper and easier to maintain, and had much better front and rear visibility for switching.

EMD GP9 model of 1750 hp North American diesel locomotive

An EMD GP9 is a four-axle road switcher diesel-electric locomotive built by General Motors' Electro-Motive Division in the United States, and General Motors Diesel in Canada between January, 1954, and August, 1963. US production ended in December, 1959, while an additional thirteen units were built in Canada, including the last two in August, 1963. Power was provided by an EMD 567C 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. All GP9B locomotives were built in the United States between February, 1954, and December, 1959.

EMD GP60 model of 380 American 3800hp Bo′Bo′ diesel-electric locomotives

An EMD GP60 is a 4-axle (B-B) road switcher diesel-electric locomotive built by General Motors Electro-Motive Division between 1985 and 1994. The GP60 was EMD's first engine that was classified as a "third-generation" locomotive. Hidden behind the electrical cabinet doors on the rear wall of the cab, the GP60 concealed a trio of microprocessors that monitored and managed a host of engine, cooling system and control functions. The engine's on-board microprocessors replaced hundreds of wiring circuits, dozens of relays and all but one module card, making it an improvement among EMD's engines.

EMD GP15-1 model of 310 American 1500hp Bo′Bo′ diesel-electric locomotives

The EMD GP15-1 is a 4-axle road switcher 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".

EMD GP16

The EMD GP16 was a series of rebuilt road switcher diesel-electric locomotives, a result of a remanufacturing program initiated by the Seaboard Coast Line Railroad 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 155 EMD GP7, GP9, and GP18 road switchers.
