Query: G.N.I.S.

The Denver and Rio Grande Western Railroad constructed a narrow gauge railroad over Tennessee Pass in 1881 as part of their extension to the Aspen area in order to beat the Colorado Midland's standard gauge route to the rich mining area. In 1890, a new standard gauge line was built from Pueblo, to Grand Junction, and jointly with the Colorado Midland Railway, a tunnel was constructed about 200 ft (61 m) below the summit. In 1945, the old Tennessee Pass Tunnel was replaced by a newer tunnel. In recent times, the Rio Grande's Tennessee Pass line was the highest active mainline railroad mountain pass in the United States. The line, now owned by the Union Pacific Railroad, is currently embargoed (the tracks are out of service but still in place).
