Minturn Helpers
Everything almost seems normal in this view of the yard at Minturn, CO.  Three helper sets are visible, the majority being four-unit consists of Southern Pacific AC4400CWs.  What may not be so obvious is that within one month, Union Pacific will cease operations over Tennessee Pass, and Minturn would become a much quieter place.
