When all good men should be home in bed, BN SD-40s await their next assignment in the silent snow at Denver (Colo.) roundhouse and fuel rack about 2:00 a.m. on Jan. 28, 1989. Before DPU's, break-in-twos of loaded coal trains at the weakest point were frequent, and hence a pallet of spare knuckles was on hand at the left. A dreadful night for a conductor to be carrying one of those, about 80-lbs., alongside a stalled train.
