This locomotive model is often referred to as a Dash 8-40C or simply "Dash 8". "Dash 8" in general refers to the electrical control series, "Dash" being a carryover from the older syntax of C40-8. The "40" refers to the baseline horsepower rating (4,000 hp or 3,000 kW) of the unit, although some units may be re-rated to 4,100 hp (3,100 kW).
Later units were supplied with a wide-nose cab and are designated Dash 8-40CW, the "W" indicating a wide-nose cab.
C41-8
Some railroads, the Chicago and North Western Railway in particular, upgraded some of their units to ~4,135 hp (3,083 kW) and designated them as C42-8. This designation was modified by the Union Pacific Railroad to C41-8 after its takeover of C&NW in 1995. Former C&NW units are usually identified by a grab-iron on the front nose just above the Union Pacific shield logo, and/or the "C41-8" designation on the cab side. The final three C&NW C40-8s were built with 4,135 hp (3,083 kW), and the prior 32 units were similarly modified as well. Although none of these units were ever officially classed as C41-8 by GE, a safety cab version was built as the Dash 8-41CW.
