For this series we begin in Marshall Canyon south of Spokane. We will follow former Northern Pacific trackage to Sandpoint, ID and then the former Great Northern trackage over Marias Pass in Montana.
In 1910 the GN converted Leavenworth, WA to Troy, MT from telegraph to telephone dispatching. 1917 GN was installing upper quadrant automatic block signals Blackfoot, MT to Summit 34 miles, Essex to Columbia Falls Jct 42 miles, Stryker, MT to Rexford 31 miles, and Troy, MT to Bonners Ferry, ID 31 miles. These installations were completed in 1918. It added signals to 41 miles of single track between Newport, WA and Spokane in 1919. By the end of 1919, the GN had 444 miles of single track and 358 miles of double track with automatic block signals. However, this was about half the mileage of its neighbor to the south. The Northern Pacific had automatic block signals on 1,149 miles of single track and 558 miles of double track at the end of 1919. In 1922, GN ordered GRS automatic block signals for Newport to Bonners Ferry, ID 62 miles; Troy, MT to Rexford 79 miles; and Whitefish, MT to Stryker 30 miles.
The Great Northern was also slow to add CTC. The GN did add 18 miles of CTC between Troy and Libby, MT in 1968. While the new alignment was being built through the Flathead tunnel to bypass the Libby Dam, the BN installed CTC on two segments between Whitefish and Radnor on the east end and between Libby and Ripley on the west end in early 1970. When the new line was completed and opened on November 7, 1970 the railroad had CTC from Troy to Whitefish.
