A San Diego-bound Amtrak Pacific Surfliner (#566) heads along the Los Angeles River on its way out of Los Angeles on July 3, 2011. Mission Tower, which was one of Union Station's two towers, can be seen in the background.
Stretching from San Luis Obispo to San Diego, the Surf Line has become Amtrak's second busiest route. See the Pacific Surfliner and San Diegan in action along with trains from predecessors Santa Fe and Southern Pacific.
