The GE C39-8 is a 6-axle road switcher diesel-electric locomotive model built by GE Transportation Systems between 1984 and 1987. It is part of the GE Dash 8 Series of freight locomotives.

A total of 161 examples of this locomotive were built for two North American railroads: Conrail and Norfolk Southern Railway.

The C39-8 was a fairly unpopular locomotive with crews, cited factors such as a rough ride, tendency to overheat, frequent turbocharger issues, issues with the fuel injection system, and various other reliability issues.

Technical

The C39-8 is powered by a 3,900 horsepower (2,900 kW) V16 7FDL-16 diesel engine driving a GE GMC187A2 main alternator. The power generated by the main alternator drove 6 GE 752AG traction motors, each with a gear ratio of 83:20 and connected to 40-inch (1,016 mm) wheels which allowed the C39-8 a maximum speed of 70 mph (110 km/h).

Depending on customer options, the C39-8 carried between 3,900 to 4,500 US gal (14,763 to 17,034 L; 3,247 to 3,747 imp gal) of diesel fuel, 360 to 400 US gal (1,363 to 1,514 L; 300 to 333 imp gal) of lubricating oil, and 380 to 420 US gal (1,438 to 1,590 L; 316 to 350 imp gal) of coolant. Like most North American diesel locomotives, the C39-8 uses normal water for cooling.

The C39-8 has a maximum tractive effort of 108,600 lbf (483,000 N) at 10.8 mph (17.4 km/h).
