Los Angeles-San Diego-San Luis Obispo Rail Corridor

Since 1989, SANDAG has been a member of the Los Angeles-San Diego-San Luis Obispo (LOSSAN) Rail Corridor Agency. LOSSAN seeks to increase ridership, revenue, capacity, reliability, and safety on the coastal rail corridor from San Diego to Los Angeles to San Luis Obispo. Other members are rail owners and operators and regional transportation planning agencies along the six-county coastal corridor.  SANDAG provides staff support to LOSSAN with financial assistance from the other member agencies. More information about the LOSSAN Rail Corridor Agency can be found at

LOSSAN Joint Timetable

Also known as Amtrak’s Pacific Surfliner Corridor, more than 2.7 million intercity passengers use the 351-mile LOSSAN corridor each year. Together with more than five million commuter passengers using either Metrolink or COASTER, it is one of the busiest passenger rail corridors in the nation and Amtrak’s second busiest. The LOSSAN Corridor Joint Timetable combines the schedules of Amtrak intercity trains, COASTER commuter trains, and Metrolink commuter trains for travel between:

• San Luis Obispo
• Santa Barbara
• Ventura
• Los Angeles
• Orange County
• San Diego

LOSSAN Rail Corridor Improvements

During the next 20 years, SANDAG plans to construct approximately $1 billion in improvements in the 60-mile San Diego segment of the LOSSAN corridor, including a primary effort to double track the corridor from Orange County to downtown San Diego. To date, two-thirds of the San Diego corridor has been double tracked. Other infrastructure improvements include bridge and track replacements, new platforms, pedestrian undercrossings, and other safety and operational enhancements. Project information is available at
