The GE Dash 9-40C, also called a C40-9, was a 4,000-horsepower (3,000 kW) diesel locomotive that was built by GE Transportation Systems of Erie, Pennsylvania, between January 1995 and March 1995. The C40-9 was equipped with the 16-cylinder 7FDL-16 prime mover which is rated at a lower power than the 4,400 hp (3,300 kW) GE Dash 9-44CW that debuted a year earlier in 1994.^[1] It featured GE's direct current B13B traction motors.^[1]

The C40-9 featured the standard cab design and was the only model in the Dash-9 series to do so. It is essentially identical to the wide-cab C40-9W model otherwise. All units had rooftop-mounted air conditioner units which gave them their distinct "top hat" look.

Norfolk Southern Railway (NS) was the sole operator of this model.^[2] The company owned 125 units, numbered 8764–8888.^[3] NS specifically requested the standard cab and may have purchased more units had the Federal Railroad Administration not required it to purchase the wide-cab C40-9W version instead.^[1]
