Highway 42 runs northwest from where Highway 24 crosses the BNSF Railway's Northern Transcon,  a route operated by what Railway?
Northern Transcon The Northern Transcon, a route operated by the BNSF Railway, traverses the most northerly route of any railroad in the western United States. This route was originally part of the Chicago, Burlington and Quincy Railroad, Northern Pacific Railway, Great Northern Railway and Spokane, Portland and Seattle Railway systems, merged into the Burlington Northern Railroad system in 1970.
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.
