The EMD GP40-2 is a four-axle diesel locomotive that was built by General Motors Electro-Motive Division between April 1972 and December 1986 as part of the Dash-2 line. The locomotive is powered by a 16-cylinder EMD 645E3 engine with an output of 3,000 horsepower (2.24 MW).
production
Standard production of the type GP40-2 totaled 861 units, of which 817 were built for US railways and 44 for Mexican railways. In addition, three GP40P-2, passenger versions of the GP40-2, were built for Southern Pacific in 1974, and 279 GP40-2L (W) and GP40-2 (W) with wide-nose cabs were built between 1974 and 1976 by General Motors Diesel (GMD) built for Canadian National and GO Transit . Of the CN units, 233 were built with a taller and lighter frame to allow for a larger fuel tank. These units have been officially classified as GP40-2L, but are commonly referred to as GP40-2L (W). The remaining 35 units of the CN fleet and the 11 units of the GO transit fleet used standard frames and smaller fuel tanks; they are often referred to as GP40-2 (W) but are classified as GP40-2. The total production of the type GP40-2 and its variants amounted to a total of 1143 units.
Although the GP40-2 was a sales success, fewer units were produced than the earlier GP40 and the contemporary GP38-2 and SD40-2 . With the GP40-2, the popularity of four-axle high-performance diesel locomotives began to decline, while six-axle models became increasingly popular for their superior performance at low speeds.
power
Like the SD40-2, the GP40-2 is known for its reliability, and many of them are still in use. Changes such as the modular electronics system improved reliability over the GP40. Due to their high performance per axis, they are more suitable for use at high speeds than for high loads at low speeds.
Using the standard 62:15 gearbox (65–70 mph maximum), EMD rated the GP40-2 with a continuous pull of 55,400 lb; for compatibility with other units, most had the PF21 module, which reduced power to below 23 mph and lowered the minimum continuous speed to 11 mph.
