The Clyde/ EMD double cabbed ML2 1500Hp Co-Co B class locomotive, at Steam Rail Victoria shows off it's insides, a double streamlined cab makes these units unique, other than the smaller NOHAB designs in Europe. We start at the Number 1 end cab then walk past the locomotive to the number 2 end.
The original layout of the B class diesel-electric locomotive design was developed in the USA and was derived from the 1937 design for the E series and the shorter F series locomotives. Built by the Electro Motive Division (EMD) of General Motors (GM) at its La Grange works in Illinois, the E and F units were widely used by many US railroad companies.

During the late 1940s and early 1950s, General Motors was one of very few really experienced diesel locomotive builders in the world and the company developed an export version of its F unit design. The first customer for the export version locomotive was the Commonwealth Railways in Australia with an initial purchase of 11 single cab locomotives known as the GM class.

The Victorian Railways followed closely behind with the purchase of 26 B class double cab locomotives. The Victorian locomotives were the first to have six of the D27 motors, with a special simplified control system that allowed full power at all speeds, but reduced starting tractive effort. As with most other EMD locomotives for Australia, the B class was constructed by Clyde Engineering at Granville, west of Sydney.
This locomotive is being restored in the Newport workshops of Steam Rail Victoria
