The first locomotives to receive the new styling was the DR-6-4-2000. When the RF-16 (essentially a "debugged" DR-4-4-1500 freight locomotive with a new prime mover) was introduced in 1950, it was given the new "Sharknose" styling. The RF-16 quickly gained a reputation as a reliable and rugged locomotive with tough "lugging power."
The prime mover in F-units was a sixteen-cylinder EMD 567 series mechanically aspirated two-stroke diesel engine, progressing from model 16-567 through 16-567D. Structurally, the locomotive was a carbody unit, with the body as the main load-bearing structure, designed like a bridge truss and covered with cosmetic panels.
The EMD FP7 is a 1,500 horsepower (1,100 kW), B-B dual-service passenger and freight-hauling diesel locomotive produced between June 1949 and December 1953 by General Motors' Electro-Motive Division and General Motors Diesel.
The F7's prime mover is a 16-cylinder 567B series diesel engine developing 1,500 hp (1.1 MW) at 800 rpm. The 567B is a mechanically aspirated two-stroke design in a 45-degree V engine configuration, with 567 cu in (9.29 L) displacement per cylinder, for a total of 9,072 cu in (148.66 L).
A steam wagon is a steam-powered road vehicle for carrying freight. It was the earliest form of lorry (truck) and came in two basic forms: overtype and undertype – the distinction being the position of the engine relative to the boiler .
600-602 original prime movers replaced with 4,400 hp (3,300 kW) 7FDL16 engines. This is due to these units being pre-production models and mechanical differences between them and the production model. 603-699, 5000-5016 114 October 1998-April 2000 603-699, 5000-5016's original prime movers replaced with 4,600 hp (3,400 kW) 16 cyl.
The turbocharger was the then-new EMD mechanically assisted turbo-compressor. During engine startup, and at lower power levels, during which there is not sufficient exhaust heat energy to drive the turbine fast enough for the compressor to supply the air necessary for combustion, the engine drives the compressor through a gear train and an overrunning clutch.
The EMD SD90MAC is a model of 6,000 hp (4,470 kW) [1] C-C diesel-electric locomotive produced by General Motors Electro-Motive Division (EMD). It is, with the SD80MAC, one of the largest single-engined locomotives produced by EMD and among the most powerful diesel-electric locomotives, surpassed only by the dual-engined DDA40X.
