The Helix on the PV&WRR

PV&WRR Helix

The helix on the PV&WRR allows the trains to gain access to the hidden yard which is located below the town of Arapaho. Trains complete two full 360 degree loops prior to entering the hidden yard. The helix structure also serves as part of a large curve to allow trains leaving Arapho to gain elevation on the way to Eagle and the White River Mining District.
