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 It replaced the Dash 8 Series in the mid-1990s, and was superseded by the Evolution Series in the mid-2000s.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.
The Dash 9 Series is an improved version of the Dash 8 Series. Like that 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 HiAdTM high adhesion trucks, with low weight transfer characteristics and microprocessor controlled wheelslip.
A specification common to all Dash 9 Series six axle models is the AAR wheel arrangement known as C-C
This version of the Dash 9 was manufactured between January and March 1995. All 125 examples of this model are owned by the Norfolk Southern Railway.
The C40-9 is the only model in the Dash 9 Series to feature the standard cab design. All were built with rooftop-mounted air conditioners which gives them a rather unusual and distinctive look - and were quickly coined "top hats" by the railfan community. Other than the standard cab, the model is identical in all specifications to the wide-nose "North American" safety cab Dash 9-40CW (or C40-9W) model (see below).
NS specifically requested the standard cab, and may have purchased more units had the Federal Railroad Administration not required it to purchase the wide-nose C40-9W version instead. Besides, standard cab GE's had become more expensive by the mid-1990s, since they were now considered optional equipment by the builder, and thus priced as such, and when a carrier is purchasing one or two hundred units of a particular model at a time, even a slight extra price for a customized cab can add hundreds of thousands of dollars to the cost of a locomotive order.
