Railroad in the United States
The Sunset Route is a main line of the Union Pacific Railroad running between Southern California and New Orleans , Louisiana .[ 1]
The name traces its origins to the Galveston, Harrisburg and San Antonio Railway , a Southern Pacific Railroad subsidiary which was known as the Sunset Route as early as 1874.[citation needed ] The line was built by several different companies and largely consolidated under Southern Pacific, with completion at the Colorado River in 1883.[ 2] Its construction prompted a Frog war at the Colton Crossing , where it intersects the Southern Transcon , then owned by the Atchison, Topeka and Santa Fe Railway , and now by BNSF Railway .
The first trains departed for through service between Los Angeles and New Orleans on February 5, 1883.[ 3]
Upon Southern Pacific Railroad's merger with Union Pacific in 1996, less than 25% of the route was double-tracked .[ 4] Efforts to expand double-trackage were ongoing as of the late 2000s and early 2010s,[ 5] with over 70% of the route having two tracks by 2012.[ 4]
The line is primarily used for freight by the Union Pacific. BNSF shares ownership of the Lafayette Subdivision.[ 6] By 2007, 45 trains daily were operating through Maricopa, Arizona .[ 5] The Amtrak Sunset Limited operates three round-trips weekly over the entirety of the route with the Texas Eagle attached between San Antonio and Los Angeles.
