One of the mainlines on BNSF's triple-tracked line through Santa Ana Canyon is used to park empty Intermodal trains that are awaiting space in either Los Angeles' Hobart Yard or in the ports of Long Beach/Los Angeles. The railway even installed air compressors along this line to keep the air brakes on these locomotive-less trains charged to prevent run-aways. Train Y-LAC1151-15 is a yard job from Hobart Yard, some 30 miles to the west, that operated as light engines to this spot, Esperanza, to pick up cars deposited here on November 6 – eight days earlier – by train S-LPCLHG2-03 (Chicago's Logistics Park to Los Angeles Harbor's GGS). BNSF ES44AC 5995, ES44C4 8213, ES44DC 7852 and ES44C4 3877 will haul this train west later in the day. There was another train (again, sans-locomotives) west of Esperanza, and a third east of here. There were likely several more stored in the Canyon as well, since there are about seven miles of track set up for storage between Esperanza and Prado Dam.
