The "Papa Bush" engine, SD70ACe #4141 heads a fast moving intermodal under the iconic Pomona footbridge and past the SP depot. The train had come in on the Sunset Route, but is about to move over to the Los Angeles Sub soon after this shot. It was a Marian, Arkansas to Long Beach train, originating at the Arkansas Intermodal Terminal, outside of Memphis, Tennessee and travelling to the Intermodal Container Transfer Facility (ICTF) in Carson, California, outside of Long Beach.
