Electro-Motive’s four-wheel road-diesel truck, named for the mechanical engineer who designed it, Martin Blomberg, was introduced on the NW3 and FT models of 1939. Since then the Blomberg truck has been used under tens of thousands of diesels, including new models introduced more than 75 years later.

The high quality of the Blomberg trucks was almost certainly another factor in North American railroads choosing diesel power over steam traction.
