Amtrak San Diegan 573 passes between the Pacific Ocean (beyond the train) and the Agua Hedionda Lagoon (which Santa Fe's Fourth District - also known, for obvious reasons; as the "Surf Line" - bisects) as it makes its way from San Diego to Los Angeles on June 5, 1985. AMTK F40PH 221 is pulling a seven-car train comprised of a former US Army troop kitchen car converted by Amtrak to a bagagge car, an Amfleet coach, an Amfleet Amcafe and four more Amfleet coaches. The train has just passed Carlsbad, California's Encina Power Station, a natural gas and oil-fueled electricity generating plant. Just two or three miles ahead is the stop in Oceanside.
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.
