Montana Rail Link's present status and main line date back to 1987, when MRL under Missoula businessman Dennis Washington agreed to lease Burlington Northern's southern Montana main line between Sandpoint, Idaho and Huntley, Montana, near Billings. This spin-off was controversial as it happened during contract negotiations between Burlington Northern and the United Transportation Union. MRL workers are represented by various unions. Montana Rail Link trains operate between Billings, MT and Spokane, WA using trackage rights over BN successor BNSF Railway's tracks connecting those points.
