The GE C40-8W is a 6-axle diesel-electric locomotive built by GE Transportation Systems from 1989 to 1994. Often referred to as the Dash light series, it is part of the GE Dash 8 Series of freight locomotives. This locomotive model is distinguished from the predecessor Dash 8-40C by the addition of a newer "wide" or "safety" cab.

The C40-8 model and its variants (C40-8W, C40-8M, and C44-8W/C41-8W) began General Electric's dominance in locomotive manufacturing. This reign lasted from the 1990s until GE sold its transportation division to Wabtec Freight in February, 2019.
