The Red River Lumber Company at its Westwood operation developed its own fire trains used to fight forest fires. Of course, Red River had its extensive railroad logging network. However, if Red River wanted to access the Southern Pacific’s railroad tracks between Westwood and Susanville there were protocols set by Southern Pacific. In 1936, a Southern Pacific Bulletin stated ”The fire train of the Red River Lumber Company may make the following speeds: Between Mason and Westwood Junction, 35 MPH’ Between Westwood Junction and Susanville, 25 MPH; and through all tunnels, 10 MPH.” I do not know what type of restrictions the Western Pacific imposed.
