Southern Californians who rely on the train may have a tough time traveling south this weekend.

Metrolink service south of San Juan Capistrano will shut down due to maintenance. Crews are scheduled to replace rocks along the shoreline to secure the railroad tracks.

Metrolink Orange County Line and Inland Empire-Orange County Line trains will only run to and from San Juan Capistrano on Saturday and Sunday. The rail system won’t be providing buses or other alternative transportation during the shutdown.

Amtrak will be shutting down service south of Irvine on Saturday and Sunday as well. It will provide buses for Amtrak passengers between Irvine and San Diego. North County Transit District will work on the Los Peñasquitos Lagoon Bridges and the Elvira to Morena Double Track project.
