In the wake of this setback, the Santa Fe was approached by the Citizens Railroad Committee of San Diego, who had formed a syndicate for the purpose of building a rail line to connect with the A&P in eastern California. Santa Fe provided financial assistance to the group, which also founded the California Southern Railroad Company (CSRR) on October 23, 1880. A roundhouse, workshops, and classification yards were built in National City, a suburb of San Diego. A wharf was also constructed to accommodate ship traffic. Initial plans were made to construct 18 miles (29 km) of main line track extending north from the new complex. As of January 12, 1882, the California Southern commenced regular passenger and freight service between its National City terminus and Fallbrook Junction, just north of Oceanside.
