Engines with a future planned block 4 upgrade would be expected to deliver nearly 10,000 horsepower (7,500 kilowatts). [19] An ongoing problem with the engines was their propensity for surging or stalling with 68 incidents reported between 2003 and October 2016 though this rate had reduced after the introduction of the Block 3 engine version.
The EMD AEM-7 is a twin-cab four-axle 7,000 hp (5.2 MW) B-B electric locomotive built by Electro-Motive Division (EMD) and ASEA between 1978 and 1988. The locomotive is a derivative of the Swedish SJ Rc4 designed for passenger service in the United States.
By increasing the output of the 16-710-G3 engine from 4,000 to 4,300 horsepower (3,000 to 3,200 kW), the SD75 was a reality. The "M" in the model designation is the style of the cab, in this case the North American style cab. The "I" model has an "Isolated Cab", or a "WhisperCab" in EMD speak, which reduces noise and vibration in the cab.
The EMD SDP40F is a six-axle 3,000 hp (2.2 MW) C-C diesel–electric locomotive built by General Motors Electro-Motive Division (EMD) from 1973 to 1974. Based on Santa Fe's EMD FP45, EMD built 150 for Amtrak, the operator of most intercity passenger trains in the United States.
The engines are capable of shorter startup times from idle to load (100 rpm/s) than traditional medium speed diesel engines. [41] To achieve mass balance and distribution within the locomotive, the engines are situated on either side of the transformer, which is located in the center of the locomotive. [ 24 ]
It was powered by a 20-cylinder version of EMD's 710G prime mover, and was the second diesel locomotive by GM-EMD to use a V20 engine, since EMD's SD45 series. 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 ...
These locomotives use a new version of the GE 7FDL-8 engine that meets the same emission standards as the GE Dash 9 Series locomotives. The power output of CM20EMPs is 2,250 horsepower , equal to that of EMD G26 , and 100 hp more than the 2,150 hp CC203s/ GE U20C .
The EMD GP10 is a diesel-electric locomotive that is the result of rebuilding a GP7, GP9 or GP18.. The Illinois Central Railroad had three separate rebuild programs to upgrade their old EMD GPs and GPs that they had purchased from equipment dealers such as Precision National Corporation in Mount Vernon, Illinois.
