Sorrento to Miramar Double Track

SANDAG is working to add approximately three miles of second main track to the San Diego region’s coastal rail corridor between the Sorrento Valley Station and Miramar Road in the City of San Diego. The project is being designed and constructed in two phases. The first phase, now complete, added a mile of double track and replaced an aging wooden trestle bridge south of the Sorrento Valley COASTER station. The second phase, now in the environmental review process, will add another two miles of second track and straighten the sharp curves that slow passenger and freight trains as they climb Miramar Hill. Combined with previous construction efforts, the project will create more than nine miles of continuous double track along the LOSSAN corridor. 

The proposed enhancements are part of a multi-modal strategy to improve the movement of people and goods within the congested I-5 North Coast Corridor. The project is a critical part of the 351-mile LOSSAN rail corridor and serves as a vital link for passenger and freight movements in San Diego County.
