Excerpt from Wikipedia
The Flathead Tunnel, also known as the Breakfast Tunnel, is a 7-mile-long (11 km) railroad tunnel in the Rocky Mountains of northwest Montana near Trego, approximately 28 miles (45 km) west of Whitefish. Located on the BNSF Kootenai River Subdivision, it is the second-longest railroad tunnel in the United States after the Cascade Tunnel.
Construction began in 1966 and the tunnel opened on November 7, 1970. It was built by the Burlington Northern Railroad as part of a new 60-mile (97 km) bypass of part of the existing route that had to be abandoned due to changes caused by the construction of Libby Dam.
As of 2018 the tunnel is used by about 50 freight trains each day as well as Amtrak's Empire Builder. Speed through the tunnel is approximately 50 miles per hour (80 km/h). Fans and a door at the east portal are used to ventilate the tunnel and clear it of diesel locomotive exhaust.
