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]
