The Cruach snow shed, at 205 yards long, had a corrugated iron roof in three sections; in summer the centre section was removed; in 1944 it was said to be the only snow shed on a British railway.

In order to keep the higher portions of the Sierra grade open in the winter, of timber snow sheds were built between Blue Ca�on and Truckee in addition to utilizing snowplows pushed by locomotives, as well as manual shovelling.

This locomotive was necessary because the standard configuration EMD SD45 could not get a sufficient amount of cool air into the diesel locomotive's radiator while working Southern Pacific's through snow sheds and tunnels in the Cascades and Donner Pass.

Snow sheds or avalanche galleries are a common sight on railroads in mountain areas, such as the Donner Pass in the United States or many of the I-90 near Keechelus Lake, though it was removed in 2014 in preparation for the construction of bridges to replace it.

Inside tunnels and snow sheds hot exhaust from lead units would accumulate near the top of the tunnel or snow shed and be drawn into the radiators of trailing EMD ( non-tunnel motor ) locomotives, leading these locomotives to shut down as their diesel prime mover overheated.

The new tunnel was started in December 1925, and was built in just over three years by A . Guthrie of St . Paul, Minnesota; the aim was to finish by the winter of 1928 1929 so that further maintenance on deteriorating snow sheds could be avoided.

Despite the fact that the line was enclosed in almost continuous snow sheds near the top of the pass, trains were often stranded for several days ( and in some cases for up to 30 days ) during heavy winter snowstorms because the snow could fall through the wood planking of the sheds.

In addition to the argument for better regularity on the Bergen Line, NSB pointed out that the cost structure of railway operations had changed, making it relatively more expensive to operate snow sheds, that required rebuilding about every twenty years, than to build a tunnel, that would be excavated using heavy and automated machinery.
