Great Northern F7A 314-A at Belknap St in Superior August 1965. This EMD cab unit was built in April 1952, Became BN 644 and was retired in December 1980. The huge backshop in the background was, at this time, being used to maintain the track equipment for the entire Great Northern Railway. This function started around 1960 and lasted into the mid 1980s on the BN. It was sold to Manions Wholesale Building Supplies and still stands today. Karl Henkels Photo from my Collection.
