Something no longer seen on passenger trains today are the wisps of steam that, on cooler days, enveloped much of the train. Amtrak SDP40F 503, powering San Diegan 770, is clearly equipped with a steam generator for train heat as it makes its stop in Fullerton, California, on a cool Halloween morning in 1974. In cold weather, that steam certainly made getting on board the train very inviting! (October 31, 1974)
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.
