I love the bicentennial locomotives the railroads created during the 1974 through 1976 period as part of the 200th anniversary of America. The first was the Seaboard Cost Line's U36-B. I don't have it as the only one made that I am aware of was Athearn's in the 70s. Unfortunately, all of their U-boats were not true to scale in terms of the hood width. And none of the current scale hood GEs from P2K, Atlas, et al is made in a U36-B with EMD Bloomberg trucks.
But, I have others, all C-truck versions. Still would like to find a Milwaukee Road SD40-2 version.
