HOME BNSF Railroad Snowsheds

Snowshed at Stampede Pass

Snow avalanches are always a potential hazard for railroads in some of the mountain regions, and these snowsheds provide protection for the rail line on the east and west ends of the 2-mile long Stampede Pass railroad tunnel. Large, L-shaped units, with a vertical leg 2' thick x 4' wide x 33' high and a horizontal leg 3' thick x 4' wide x 12' long, are joined by a bolted connection and structural slab at the top to form a rigid frame capable of carrying hundreds of feet of snow in the event of an avalanche.
