Set of power Bison yard Buffalo.
Both EL and N&W power were mingling at the Joint Bison yard in Buffalo
A N&W F7A leads a pair of geeps with a train from Canada as it heads to Bison Yard. The train is on the bridge that used to go across the West end of Frontier yard.
Sometime in the very early seventies, if you remember when it was you weren't really there.
