Tracklaying continued and proceeded steadily northward until August 14, 1882, when a connection was made with the Southern Pacific's line in Colton. The California Southern's attempts to cross over the SP tracks a year later led to a frog war that ended on August 11, 1883, with a court order in the CSRR's favor. A track extension to San Bernardino was completed and the first regular passenger train arrived on September 13. The line became part of the Atchison, Topeka and Santa Fe Railroad's transcontinental rail line in 1885 via an extension of the California Southern from Colton north over the Cajon Pass to Barstow. Santa Fe completed the "Surf Line" run between Los Angeles and San Diego under the auspices of its subsidiary, the Southern California Railway (a different subsidiary from the California Southern), on August 12, 1888. The route was initially referred to as the Los Angeles—San Diego "Short Line" as it replaced the circuitous inland route through Temecula Canyon.
