A quartet of Union Pacific Railroad AC4400CWs sit on the Dolores Industrial Lead after cutting off the westbound train they brought to the Intermodal Container Transfer Facility (ICTF), in nearby Carson. The four AC4400CWs are UP 6498, 6176 (ex-Southern Pacific 173), 6818 and a fourth unit the number of which I failed to note. (Compton, California – May 4, 2012)
