In this week’s Saturday Infrared photo, we catch BNSF 97117 bringing up the rear as DPU on a loaded coal train working its way through the loop at the TVA power plant at Kingston, Tennessee, on April 28th, 2024.
DPU. Stands for Distributed Power Unit, a locomotive set capable of remote-control operation in conjunction with locomotive unites at the train’s head end. DPUs are placed in the middle or at the rear of heavy trains (such as coal, or grain) to help climb steep grades.
