The Flathead Tunnel is a 7.01-mile (11.3-km) railroad tunnel in the Rocky Mountains approximately 42 miles (67 km) to the west of Whitefish, Montana. It is the second-longest tunnel in the United States. Speed through the tunnel is approximately 50 mph (80 km/h).
The construction of Libby Dam required the relocation of 60 miles (~100 km) of the Burlington Northern Railroad tracks, relocating the town of Rexford, MT and the building of a new tunnel which opened in 1970. The east portal has a door that can be closed and fans to ventilate the tunnel. It is part of the BNSF Railway system and used by Amtrak's Empire Builder.
