The BGCM route had been acquired from Camas Prairie RailNet (CSPR) in December 2002, a subsidiary of North American RailNet, which had acquired the entire Camas Prairie line in April 1998 from the line's previous (and original) co-owners, Union Pacific Railroad and Burlington Northern and Santa Fe Railway. CSPR received permission from the Surface Transportation Board to abandon the Grangeville Branch in September 2000 and made its last run on that line in late November. Watco had acquired the remainder of the Camas Prairie RailNet in March 2004.
