Sullivan's Curve is located at MP 62.5, where the original Santa Fe mainline passed through Mormon Rocks. Along the way between San Bernardino and Barstow the line passes through more than a dozen settlements that all owe their existence to the presence of the pass over the mountains.

The mainline is mostly double track with some sections of triple track. The Cajon Subdivision mainline is the busiest within Southern California. The line has a total length of 81.4 miles and, when completed, it filled the final gap in the Southern Pacific transcontinental railroad from San Diego to Chicago. It provides one of the important transportation links to the Los Angeles Basin.Ĭonstruction of the Cajon Pass line began in 1882 from San Bernardino and reached Barstow in 1885 having suffered several delays along the way. Created by the San Andreas Fault thousands of years ago, the Cajon Pass has an elevation of 1,277 meters (4,190 ft.).
