The General Electric Dash 8-41CW or Dash 8-41W (C41-8W) is a variation with the same 16-cylinder engine upgraded to 4,135 hp (3,083 kW). 154 were produced between 1993 and 1994 for both the Union Pacific and Santa Fe (ATSF) railroads, and some Dash 8-40CW units were also uprated to Dash 8-41CW standard by the railroads.
This model is a variation of the C40-8W with the same 16-cylinder engine uprated to 4,135 hp (3,080 kW). A total of 154 C41-8Ws were produced between 1993 and 1994 for both UP and ATSF. Some Dash 8-40CW units were similarly uprated to Dash 8-41CW standard by the railroads.
However, for simplicity, many railroads decided to use designations which follow the pattern of the Dash-7 line. Thus, for example, the Dash 8-40C is usually rendered as "C40-8". The "W" suffix indicates the then-optional wide-nose "North American" safety cab. For example, the Santa Fe used the designation "B40-8W" for GE's "Dash 8-40BW".
The Dash 8-40CM is powered by a 4,000-horsepower (3,000 kW) 7FDL-16 diesel engine driving a GE GMG187 main alternator.The power generated by the main alternator drives six GE 752AG or 752AH direct current traction motors, each with a gear ratio of 83:20 and connected to 40-inch (1,000 mm) wheels which allow the Dash 8-40CM a maximum speed of 70 mph (110 km/h).

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.
