This was the first model of any locomotive series to be fitted with microprocessor-equipped engine control units.
 A total of 581 examples of the model were manufactured between 1987 and 1992.

The C40-8 has a traditional narrow short hood, but otherwise its external appearance is almost the same as that of the later Dash 8-40CW model.

The most important customer for this model was UP, which ordered 257 of them.

Other large orders for the model came from Chicago and North Western Transportation Company (77 units), Conrail (25), CSX (147) and Norfolk Southern (75).

The remaining four units were supplied to Estrada de Ferro Carajás of Brazil.

Power output: 4,000 hp (2,980 kW)
