GE Dash 9 Series

The Dash 9 Series is a line of diesel locomotives built by GE Transportation. It replaced the Dash 8 Series in the mid-1990s and was superseded by the Evolution Series in the mid-2000s, and its locomotives are some of the most common in the United States. It is an improved Dash 8, with a microprocessor engine control unit and a modular body. All models are powered by a 16-cylinder turbocharged GE 7FDL four-stroke diesel engine with electronic fuel injection and split cooling, and ride on HiAd high adhesion trucks with low weight transfer and microprocessor-controlled wheelslip control. The six-axle models share the C-C wheel arrangement, and the C40-9 was the only model with the standard cab.
