BN 9794, a former NP FP7A, makes a move with an Amtrak F7B and another FP7 at Harrison St. roundhouse in Minneapolis, MN. The power was in use in the summer of 1973 by Amtrak to protect Empire Builder and North Coast Hiawatha service at the Twin Cities. As Amtrak acquired SDP40Fs, the 9794 would eventually return to BN for freight service before being retired.
