Montana Highway 42 Montana Highway 42 (MT 42) is a short, 2.9 mi state highway in the U.S. state of Montana, connecting Montana Highway 24 with downtown Glasgow. Formerly Highway 24W, Highway 42 (its route number a reversal of "24") runs northwest from where Highway 24 crosses the BNSF Railway's Northern Transcon, staying parallel to the tracks until it turns right in Glasgow's downtown and dives under the railroad to meet with and terminate at U.S. Route 2.
Overland Route (Union Pacific Railroad) The Overland Route was a train route operated jointly by the Union Pacific Railroad and the Central Pacific Railroad / Southern Pacific Railroad, between Council Bluffs, Iowa / Omaha, Nebraska, and San Francisco, California over the grade of the First Transcontinental Railroad (aka the ""Pacific Railroad"") which had been opened on May 10, 1869. Passenger trains that operated over the line included the "Overland Flyer", later renamed the "Overland Limited", which also included a connection to Chicago. Although these passenger rail trains are no longer in operation, the Overland Route remains a common name for the line from California to Chicago, now owned entirely by the Union Pacific.
