The Shields River Valley Railway built a 22-mile line, completed in 1909, north from a connection on the Northern Pacific at Mission, Montana, to serve the agricultural communities of Grannis, Chadborn, Clyde Park, and Wilsall. A year later it became a NP branch, eventually becoming the property of Burlington Northern Railroad in 1970. The line was abandoned by BN in 1985, but amazingly, in 2022, the rail is still in place at many locations. At Clyde Park on June 28, 2022, two red grain elevators appear to be in quite remarkable shape, even though it has been at nearly 40 years since a train plodded up the branch. The tracks are still in, barely visible through lush grass of a wet spring.
