The St. Maries River Railroad began service on May 23, 1980, over trackage that previously had been owned by the bankrupt (and now-defunct) Chicago, Milwaukee, St. Paul & Pacific Railroad, also known as the Milwaukee Road.
The St. Maries River operates between Plummer, Idaho and St. Maries, Idaho on what was the Milwaukee Road's Pacific Northwest main line across the Rockies. The railroad also operated on the Milwaukee Road's former Elk River branch line between St. Maries and Bovill, Idaho.[1]
For several years from 1980 until the mid-1980s, Potlatch also owned and operated 45 miles of adjoining former Milwaukee Road trackage, between St. Maries and Avery, Idaho, as a private logging railroad that connected with the St. Maries River Railroad. The federal government condemned the logging line between St. Maries and Avery in the mid-1980s, prompting its shutdown.
In 2010, Potlatch sold the St. Maries River Railroad for $1.6 million[2] to Mike Williams of the Missouri-based Williams Group, which owns other short line railroads in Idaho, Missouri and South Dakota, including the BG&CM Railroad.[3]
The St. Maries River Railroad connects with the Union Pacific Railroad at Plummer. The line to Bovill, ID is no longer in service as the connecting Washington and Idaho Railway line has been abandoned between Bovill and Harvard, ID.
