The first unit to go into series production was a six-cylinder, in-line engine (6 PC1 L) for the electricity generating plant of Bamako, Mali. With a bore of 400 mm, the engine developed 180 kW per cylinder. Its first marine application for the PC1was in 1955, aboard the French Navy ship Borée (two engines).
For manufacturer EMD, the construction of the world's most powerful single frame locomotive was a sign of the company's dominance of the North American diesel locomotive market, with only GE Transportation an equal competitor. The DDA40X also pioneered a number of new technologies that would go on to be incorporated in future EMD designs.
