Riverside–Rialto was an interurban train service operated by the Pacific Electric Railway from 1914 to 1940, running from Downtown Los Angeles to Downtown Riverside. This was the longest service in the Pacific Electric system, and the only line to have exclusive trackage owned by the Union Pacific instead of the Southern Pacific Railroad. The line reached its highest ridership the year it opened but never recovered at a time when the Inland Empire was far less populated and a commute of that distance was rare.

History[]

The line was initially constructed in 1907 by the Riverside Portland Cement Company to link their new plant to the national rail network at Riverside. Operating as The Crescent City Railway Company, service was contracted out to The Riverside & Arlington Railway Company who ran the first electric car on May 1, 1908. The line primarily served plant workers. Riverside & Arlington would go on to be absorbed into Pacific Electric as a result of the Great Merger.^[1] The line was opened to Bloomington on May 20, 1911,^[2] and finally to Rialto on March 24, 1914.^[3] Initially only local service was provided, and passengers from Los Angeles continuing to Riverside were encouraged to take the longer trip and change at San Bernardino.^[3]

On March 15, 1915, most local service was replaced with through trips to the Pacific Electric Building in Downtown Los Angeles. Cars were connected to San Bernardino Line trains.^[3] Between May 1921 and 1929, local cars made trips as far north as Foothill Boulevard in Rialto — the only scheduled trips to that point.^[3] All trips became through-routed to Los Angeles on November 2, 1931 as service to the cement plant was discontinued. This was short lived, as by 1935 all but one trip had been reverted to local with through routing ending entirely in 1938. Service was reduced to a single trip between Riverside and Rialto by June 9, 1940 and discontinued outright on November 18.^[3]
