A pair of freight trains await their departure times at Union Pacific's West Colton Yard.
UP SD70ACe 8552 may head west to Arizona and beyond, or it could head north to the northern part of California … the division point is just on the other side of the bridge on which I am standing.
BNSF ES44DC 7727 and train H-WCLBAR1-20, however, will, as with all other BNSF trains departing here, head to Barstow, where its cars will be broken up and assigned to new trains heading east … or, as with UP, perhaps north. (Colton, California – April 21, 2018)
