Cow-calf Locomotives
In rail transport, a cow-calf (also cow and calf) locomotive is a set of switcher-type diesel locomotives. The set usually is a pair; some 3-unit sets (with two calves, also known as herds) were built, but this was rare. A cow is equipped with a driving cab; a calf is not. The two are coupled together (either with regular couplers or a semi-permanent drawbar) and are connected with MU cables and brake lines so that both locomotive units can be operated from the single cab. Cows are analogous to A units and calves to B unit road locomotives. Both have prime movers. Like the early EMD FT locomotives, the Cow-calf sets were typically built as mated pairs, with the Cow (or cabbed unit) and calf (or cabless unit) sharing a number. However this was not always the case, with over time many of the sets being broken up and couplers added to aid with versatility. Cow-calf locomotives can be distinguished from the sometimes very similar looking slug and slug mother sets by the fact that ...

Electro-Motive Diesel
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. Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, a designer and marketer of gasoline-electric self-propelled rail cars founded in 1922 and later renamed Electro-Motive Company (EMC). In 1930, General Motors purchased Electro-Motive Company and the Winton Engine Co., and in 1941 it expanded EMC's realm to locomotive engine manufacturing as Electro-Motive Division (EMD). In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, which formed Electro-Motive Diesel to facilitate the purchase. In 2010, Progress Rail completed the purchase of Electro-Motive Diesel from Greenbriar, Berkshire, and others. EMD's headquarters, engineering facilities and parts manufactur ...

EMD TR1
The EMD TR1 was a two-unit "cow-calf" diesel locomotive built by General Motors Electro-Motive Division of La Grange, Illinois, in 1941. Two pairs were built for the Illinois Central Railroad, the only purchaser. The locomotive units strongly resembled the EMD NW3, with a long frame, Blomberg B road trucks, and a large cab connected to a wide area of hood that tapered going forward. The locomotives incorporated the machinery of the EMD FT in switcher bodywork; a V16 EMD 567 diesel engine of in each unit. The cow and calf units were semipermanently coupled together with a drawbar instead of couplers, in similar fashion to the FT's twin-unit sets. The two locomotive pairs were numbered 9250A&B and 9251A&B, later renumbered 1350A&B and 1351A&B. They initially were assigned to Markham Yard south of Chicago, IL, but by the early 1950s had been reassigned to the yard at East St. Louis, IL. Both remained in this service until they were retired in 1966 and traded in to EMD in par ...

Belt Railway Of Chicago
The Belt Railway Company of Chicago , headquartered in Bedford Park, IL, is the largest switching terminal railroad in the United States. It is co-owned by six Class I railroads — BNSF Railway, Canadian National Railway, Canadian Pacific Railway (the BRC's north-south main line's northern terminus is, like the Indiana Harbor Belt, the Milwaukee District West Line in Chicago's Cragin neighborhood), CSX Transportation, Norfolk Southern Railway, and Union Pacific Railroad — each of which uses the switching and interchange facilities of the BRC. Owner lines and other railroads bring their trains to the Belt Railway to be separated, classified, and re-blocked into new trains for departure. The BRC also provides rail terminal services to approximately 100 local manufacturing industries. The company employs about 440 people, including its own police force. BRC trackage The BRC has 28 miles (45 km) of mainline route with interchanges to each of its owner railroads, a ...

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. A road switcher must be able to operate and have good visibility in both directions. As a road engine, a road switcher must be able to operate at road speeds, with suitable power and cooling capacity. It has high-speed road trucks rather than low-speed switcher only trucks. Modern road trucks are always equipped with "frictionless" roller bearings, whereas switcher trucks were almost always equipped with "friction" plain bearings, until plain bearings were outlawed in interchange service on both railcars and locomotives. Overview For the reasons given above, road switchers are generally hood units. The set-back cab of a hood unit provides more safety in the event of a collision at speed than most switcher designs, and the rear visibility is ...
