The Transcon is one of the most heavily trafficked rail corridors in the western United States: as of 2006[update], an average of almost 90 trains daily (over 100 trains on peak days) passed over the section between
Belen and
Clovis, New Mexico, with each train typically 6,000 to 8,000 feet (1,800 to 2,400 m) long.[1]
History
The
Atchison, Topeka and Santa Fe Railway completed a railroad between
Chicago and
Southern California in the 1880s. The route, built in stages, was less than ideal, especially where it crossed
Raton Pass and
Glorieta Pass. The steep
grades posed operational problems, including congestion, slow speeds, and the need for
helper engines. As an interim solution, a second track, with a longer tunnel, was opened at Raton in 1908, but this simply added capacity, and the grades remained. In 1902 the Santa Fe began surveying a new cutoff that would bypass this segment entirely. Much of the route had already been constructed by subsidiaries, such as the
Southern Kansas Railway, which built a branch to
Amarillo, Texas, in the 1880s, and the Pecos Valley and Northeastern Railway, an 1899 extension from Amarillo to
Pecos via
Texico, New Mexico.[2]
Belen Cutoff
To complete the line between Texico and a point northwest of
Belen, New Mexico, the Santa Fe incorporated the
Eastern Railway of New Mexico in October 1902, and began construction of the Belen Cutoff the next January. The entire line was completed on July 1, 1908, allowing through freight trains to bypass the 3–3.5% grades of the old line for the maximum grade of 1.25% (at
Abo Canyon) on the new line. (Most passenger trains continued to use Raton Pass so as to serve Colorado.) The Pecos Valley and Northeastern (but not its Texas subsidiaries, because of
Article X of the Texas Constitution) was consolidated into the Eastern in March 1907, and in January 1912, the property of the Eastern was conveyed to the Santa Fe.[3]
Other improvements
To connect central Texas to this line, the Pecos and Northern Texas Railway completed the Coleman Cutoff, running southeast from Texico to the Santa Fe subsidiary
Gulf, Colorado and Santa Fe Railway at
Coleman, in 1914. A third line was almost completed in the 1920s and 1930s, when the Santa Fe built the majority of the planned
Dodge City–Colmer (Colmer Cutoff), which would provide a second bypass of Raton (but not Glorieta), but construction stopped at Farley, and the line was torn up west of
Boise City in 1942.[4]: 18–31
The completion of the Belen Cutoff did not end improvements to the transcontinental route. The 47-mile (76 km) Ellinor Cutoff opened in 1924, cutting through the
Flint Hills from the original main line at
Ellinor, Kansas, southwest to
El Dorado on the main line to Texas. This allowed trains bound for the Belen Cutoff to cut directly to
Mulvane, bypassing
Wichita to the southeast.[4]: 36–37 To the west, in Arizona, the Santa Fe constructed a new line between
Williams and Crookton, bypassing the sharp curves and steep grades of the line via
Ash Fork built by the
Atlantic and Pacific Railroad in the 1880s.[3] The $19.3-million realignment opened on December 19, 1960, and the old line was abandoned west of the
Phoenix connection at Ash Fork.[4]: 53 Smaller improvements included installation of
centralized traffic control on the Belen Cutoff in the 1940s.[4]: 29 Also, by October 2018, the entire Southern Transcon was double-tracked, except for two bridges; and, projects were underway to add triple- and even quadruple-track along the busiest parts.[5][6]
The Southern Transcon railroad corridor is made up of the following BNSF rail lines which are referred to as subdivisions, in order from west to east.[7]
Parts of the route are utilized by passenger rail services — BNSF does not operate regular passenger trains outside of the
Chicago Subdivision.
Amtrak's Southwest Chief runs once daily in each direction on the Transcon, but via the
Glorieta,
Raton,
La Junta Subdivision and Topeka between Albuquerque and Kansas City. The Pacific Surfliner also operates between
Los Angeles and
Fullerton. Until its cancellation in 1997, Amtrak's Desert Wind used the Southern Transcon between Los Angeles and
Barstow. The proposed
Coachella Valley Rail train from RCTC, which is anticipated to be operated by Amtrak, would initially run two roundtrips a day over the Transcon from LA Union Station to the Colton Crossing.
