The EMD GP7 is a four-axle (B-B) diesel-electric locomotive built by General Motors Electro-Motive Division and General Motors Diesel between October 1949 and May 1954. [2] The GP7 was the first EMD road locomotive to use a hood unit design instead of a car-body design.

2025年2月20日 · The ruggedness and reliability of EMD's 567 engine block saw GP7s remain in service on many Class 1 systems for decades. Some roads, like the Santa Fe and Illinois Central, carried out extensive rebuild programs to extend the …

2014年3月24日 · Answer for the L in GP7L L = Lightweight Frame. I trust this answers the question of what the L designation is on the GP7L and other EMD built locomotives.

In order to differentiate between the two types of air brake equipment, the model designations IGP7L" or IGP7R" are used. The GP7L is equipped with 6 BL (USA) or 6 SL (Canadian) brake equipment while the GP7R is equipped with 24 RL brake equipment.

The EMD GP7 locomotive is a versatile 4-axle road switcher, capable of both freight and passenger service. Introduced in 1949, this locomotive was the first road locomotive that EMD produced that included a hood design instead of a cowl body, such as the F and E units.

EMD, nominally 600 volt direct current, ventilated by blower. Single bearing direct connected to engine crankshaft through alternator rotor and flexible coupling. Capacity suitable to continuously transmit to traction motors the rated output of the engine under all conditions for which the locomotive is offered.

2009年6月28日 · The Electromotive Division GP7 is a 4 axle, 1,500 HP diesel-electric locomotive built by EMD from 1949 to 1954. It's 16 cylinder 567C engine was rated at 1,500 horsepower. In the late 40's, EMD was looking for a locomotive to replace the unsuccessful (and impractical) BL2.

In 1949, EMD introduced the GP7. The basic design followed most diesel switchers with the addition of a short hood instead of an end-cab. The hoods were also full height to better accommodate the diesel engine and mechanical and electrical components. In 1954 EMD upgraded the GP7 to become the 1,750 horsepower GP9.

These diesel-electric locomotives, built by EMD in 1951 for the U.S. Army, would have switched freight cars at the Holston Army Ammunition Plant in Kingsport, Tennessee. They are GP7L type locomotives, developing 1,500 horsepower. The 1824 and 1829 differ from most GP7 models, in that they have AAR type A switcher trucks.
