A Pacific Surfliner bound for San Diego passes a set of light engines being moved by hostlers at BNSF's Commerce Diesel facility. There certainly are a lot of overhead wires at this location!
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.
