Colton Crossing is a railway crossing situated in Colton, California, directly south of Interstate 10. First built in 1883, it was the site of one of the most intense frog wars in railroad construction history, leading to a personal confrontation between famed lawman Virgil Earp and California Governor Robert Waterman. The crossing was the intersection of the tracks for the Atchison, Topeka and Santa Fe (ATSF) and Southern Pacific (SP) railroads. The tracks are now owned by the SP's and the ATSF's successors, the Union Pacific (UP) and the Burlington Northern Santa Fe (BNSF) railroads respectively. The UP tracks run east–west at the crossing while the BNSF tracks run north–south (the BNSF tracks eventually head west to Los Angeles and Long Beach, parallel to the UP tracks). Metrolink trains and Amtrak's Southwest Chief use the BNSF tracks through the crossing while Amtrak's Sunset Limited utilize the UP tracks. The UP tracks come from the east through the Coachella Valley and into the yard in West Colton (onwards to Los Angeles). On the other hand, the BNSF tracks from the indirect west (Los Angeles) and direct south (Riverside and Corona) continue through the crossing and on to the yard in San Bernardino, which then head up north to Cajon Pass and eventually Barstow on the journey to Chicago.

Colton is a city in San Bernardino County, California, United States. Nicknamed "Hub City", Colton is located in the Inland Empire region of the state and is a suburb of San Bernardino, approximately 4 miles (6.4 km) south of the city's downtown. The population of Colton is 52,154 according to the 2010 census, up from 47,662 at the 2000 census. Colton is the site of Colton Crossing, which was one of the busiest at-grade railroad crossings in the United States. The crossing was installed in 1882 by the California Southern Railroad to cross the Southern Pacific Railroad tracks while building northward from San Diego. As a result of railroad acquisitions and mergers, this became the point at which the Burlington Northern Santa Fe's "Southern Transcontinental Route" crossed the Union Pacific's "Sunset Route". As traffic on each line began to soar in the mid-1990s, fueled largely by the vast increase in imports passing through the ports of Los Angeles and Long Beach, the primitive crossing became a serious bottleneck. On August 28, 2013, the at-grade crossing was officially replaced by a fly-over that raises the east–west UP tracks over the north–south BNSF tracks. Despite its status as a railroad town, Colton does not have passenger rail service. Passenger trains operated by Amtrak and Metrolink pass through Colton but do not stop there.
