Lots of first generation EMD power at the Belknap Street roundhouse in Superior, Wisconsin, in August of 1976. The 1421 is a former Northern Pacific GP7 (550) rebuilt into a GP10.
BN 133 with 3 GP10's and a GP35 have things cranked as he screams past 134 in the siding at Bow.
It appears we're headed for a cornfield meet. The Cherry Pt. Turn is hanging back just far enough for the Ferndale Turn to make a few switch moves from the Ferndale siding.
