By Highball Productions

In Supercab we take an in depth look at the development of the Supercab locomotive, from the industry standard SD40-2 and C30-7 locomotives of the '70s, the GP40-2 "Canadian" cab that started it, to the SD60M & C40-8W, the first US Supercabs, through the high tech SD90MAC and AC6000CW of today.
