Blomberg B

The Blomberg B was a "B" diesel locomotive truck. These trucks were the standard EMD four wheel truck from the FT up until the GP60. EMD introduced the truck in 1936. Unofficially it is named after Martin Blomberg, who joined the company the year before. The truck was derived from an earlier three axle truck (A1A) designed by Blomberg (described in U.S. Patent 2,189,125, filed January 29, 1938, and approved February 6, 1940), and was used starting with the FT.
