At the western portion of BNSF Railway's Transcon line between Chicago and Los Angeles, train S-LPCLBJ1-05A (Intermodal Stacks; originating at Logistics Park in Chicago IL headed for Pier J at the port of Long Beach CA) hustles through Atwood (the old Santa Fe station name which is now part of Placentia), California. ES44DCs 7386 and 7481 are on the headend, and ES44DC 7443 and ES44C4 6848 are the rear Distributed Power Units (DPU), pulling a long string of well cars loaded with containers. (The QZ on the Whistle Post sign indicates that this is a "Quiet Zone" and the train is not allowed to whistle for grade crossings, as it upsets the delicate sensibilities of the NIMBYs who live alongside the mainline.)
