Amtrak train #572, a Pacific Surfliner, passes through Orange, California, after making a stop in Anaheim (just on the other side of the 57 Freeway in the background). Behind the six cars is private car "Scottish Thistle."
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.
