Westbound Union Pacific container train cresting Nevada's Sand Pass on the morning of August 30, 2009. The train, en route from Marion, Arkansas, to Oakland, California, has just completed the one percent climb out of the Smoke Creek Desert, seen in the background. The route is part of the Western Pacific Railroad's original mainline. Successor Union Pacific continued to use the route for double-stacked container traffic until 2009, when clearance improvements allowed this traffic to run via Donner Pass, which is 70 miles shorter. Today this line sees very sparse traffic.
