BNSF tested it's first 14,000ft stack train today combining the NWO and SCO blocks into 1 train. Here is 7147E passing through Corona near Prado Dam on the San Bernardino Sub.
BNSF's Corona Local runs down the former Elsinore Line a few times a week to serve the 3M facility. The train is entering the plant on its Southward journey down the branch.
