GE DASH 9 SERIES
The Dash 9 Series is a line of diesel locomotives built by GE Transportation Systems. It replaced the Dash 8 Series in the mid-1990s, and was superseded by the Evolution Series in the mid-2000s. Dash 9 series locomotives are some of the most common in the United States.
Specifications
The Dash 9 Series is an improved version of the Dash 8 Series. Like the earlier Series, it has a microprocessor-equipped engine control unit, and a modular system of construction of the vehicle body.
All models of the Dash 9 Series are powered by a 16-cylinder, turbocharged, GE 7FDL 4-stroke diesel engine, with electronic fuel injection and split cooling.
Dash 9 Series locomotives also ride on HiAd high adhesion trucks, with low weight transfer characteristics and microprocessor controlled wheelslip.
Six axle models
Common feature
A specification common to all Dash 9 Series six axle models is the AAR wheel arrangement known as C-C.
