 The first train from San Diego arrived in Colton on August 21, 1882 (before the crossing was installed), and the first train to San Bernardino arrived just over a year later on September 13, 1883.The Colton Crossing is the location where two main rail routes serving Southern California crossed at-grade in the City of Colton.More than 110 trains used the right-angle at-grade rail crossing each day, which, until the flyover project was completed, had been a significant cause of congestion on the main lines of UP and BNSF.
