Early versions of this model differ from the Dash 8-40C only in having a "wide" or "safety" cab.
 A total of 756 examples of the model were built, with the first being delivered to Union Pacific in 1990.

The C40-8W was continuously upgraded over the course of its production.
Later model Conrail units were built with split cooling systems for the turbocharger intercooler and engine cooling (previous Dash 8 series had both on the same cooling system).

The units delivered to Conrail in 1993 and 1994 were equipped with GE's Integrated Function Displays (IFD).

Some of the C40-8Ws operated by Conrail were lease units owned by LMSX.
 The other railroads that operated C40-8Ws as original owners were ATSF, CSX, and Union Pacific.

Power output: 4,000 hp (2,980 kW)
