Looking up toward Big 10 Curve at Rocky, Colorado, sees a Burlington Northern Santa Fe train hauling coal eastbound descending the front range of the Rocky Mountains at Rocky, Colorado, on June 18, 2001. Six BNSF EMD SD70MACs power the train. In the lead are two units passing Rocky siding, while in the background on the right a mid-train DPU set of three approaching the west switch. Coming off the mesa above is a lone DPU unit on the rear that has just finished rounding Big 10 Curve.
