A westbound coal empty meets an eastbound BNSF Provo-Denver manifest at Leyden. The coal empty is headed for the West Elk Mine on the North Fork Branch. For the trip east, two of these units will be on the east end, three will be mid-train DPUs, and one will be the sole DPU on the tail end.
It is also worth mentioning that this picture marks the 7000th picture on ColoradoRailfan.com!
