The EMD SW1001 is a 1,000- horsepower (750 kW) diesel switcher locomotive built by General Motors ' Electro-Motive Division between September 1968 and June 1986. A total of 230 were constructed, mainly for North American railroads and industrial operations.
7-510: The SW1001 was developed because EMD's SW1000 model had proved unpopular among industrial railroad customers, as the heights of its walkway and cab eaves were much greater than those of earlier EMD switcher models. The overall height was similar, but the SW1000's roof was much flatter in curvature. Industrial railroads that only operated switchers often had facilities designed to the proportions of EMD's earlier switchers. The SW1001, in essence, placed
14-805: The National Harbours Board . 18 by companies in Mexico: 12 by AHMSA , 3 by Lazaro Cardenas Steel ( ArcelorMittal ), and 3 by Pemex . In Africa five were supplied to the Boke project in Guinea in the early 1970s and 18 were acquired by the railways of Morocco ( ONCF ) in 1982 as type DI 500 . In Asia the Korean National Railway acquired 28 between 1969 and 1971. One was acquired in 1980 by Foster Yeoman (vehicle code Y44 ), and another by Hanson Aggregates in 2000 both for use on quarry industrial sites in
21-612: The England. They are based at Whatley Quarry and Merehead Quarry, both part of Mendip Rail operations. Five were bought for the government railways of Saudi Arabia in 1981. Additionally 60 variants with a redesigned cab were built under license as the Renfe Class 310 for the railways of Spain between 1989 and 1991. EMD SW1000 The EMD SW1000 is a model of 4-axle diesel switcher locomotives built by General Motors Electro-Motive Division between June 1966 and October 1972. Power
28-709: The SW1000 exceeded them. As a result, most production went to railroads, not industries. EMD corrected this problem with the SW1001 , which was an SW1000 with its height and walkways lowered for better clearance. A total of 114 EMD SW1000s were built for railroads and industrial operations in the United States . One was exported to Jamaica for a mining operation and four were exported to industrial operators in Mexico . As at January 2014, two EMD SW1000s are operated by Via Rail at its Montreal Maintenance Centre. Around August 2022,
35-463: The hood and powertrain of the SW1000 with the underframe and cab of the earlier SW1200 . The EMD 645 -series diesel engine had a deeper crankcase and oil pan than the SW1200's EMD 567 -series engine. The engine had to be mounted on risers for sufficient clearance, raising the whole hood about 6 in (152 mm) above the walkway compared to the SW1000, and requiring a spacer under the hood. The cab
42-600: Was provided by an EMD 645E 8- cylinder engine which generated 1,000 horsepower (750 kW). This locomotive was built on the same common frame as the EMD SW1500 , giving it an overall length of 44 feet 8 inches (13.61 m). Over one-third of SW1000 production went to the Burlington Northern Railroad . The SW1000 was taller than previous EMD switchers, which posed a problem for industrial customers: at many facilities, tight clearances existed, and
49-566: Was similar to that of the SW1200, but not identical; it is longer, and has a different window arrangement. The SW1001 uses the same pilot plates as the SW1000; given the lower frame height, these protrude above the walkway deck height, giving the most obvious SW1001 spotting feature. The SW1001 locomotive type was used in a number of countries outside the USA: in the Americas four units were bought by Canadian businesses; two by Saskatchewan Power and two by
