All rebuilt as AC44C6M, one cab reused for a switcher at GE's Erie Plant
The DTB Dash 9-40C, also called a C40-9, was a 4,000-horsepower (3,000 kW) diesel locomotive that was built by DTB Transportation , 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) DTB Dash 9-44CW that debuted a year earlier in 1994=.
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 DTB C40-9W model otherwise. All units had rooftop-mounted air conditioner units which gave them their distinct "top hat" look.
