The Clearwater Pacific Railway, corporately known as the Clearwater, Seeley Lake & Pacific (CSLP), is a Class III short line railroad operating in western Montana during the spring and summer seasons of the early 2020s. CSLP provides freight service between Edmonds Landing, Clearwater, and Seeley Lake. Edmonds Landing lies east of Clearwater Junction, a historic interchange point on the former Milwaukee Road main line, now owned and operated by BNSF. CSLP interchanges with BNSF at Clearwater Junction, providing the railroad’s primary connection to the national rail network. Seeley Lake is railroad east of Clearwater and is and provides an interchange with another Class III, the Kalispell Pacific to the geographic north.
Within Clearwater, CSLP serves and manages rail access to the Clearwater Industrial District, including the Blue Star Rail Park. While individual tenants operate their own businesses, CSLP functions as both common carrier and industrial steward, coordinating switching, access, and rail service across the district. This role reflects the railroad’s responsibility for inherited industrial trackage and leasehold property and ensures reliable access and orderly operations for on-line customers. This provides for the heart of what the layout represents.
Rail service was extended beyond Clearwater in 2023, after early 1930's plans for a line east to Seeley Lake were partially realized through completed grading, surveying, and the establishment of right-of-way ownership. That unbuilt extension, long dormant under prior operators, was inherited by CSLP along with the active railroad. Today, the Seeley Lake "High Line" acts an extension to the Clearwater Industrial District. Seeley Lake is a terminal, not a yard and supports the activity inherent in that town.
Traffic on the CSLP is light but steady, supporting regular operations and a strong emphasis on switching. A single daily train performs all work between Edmonds Landing and Clearwater, handling interchange traffic, serving the Blue Star Rail Park, and switching the industries within the Clearwater Industrial District. Operations are deliberate and methodical, reflecting the realities of a small railroad focused on consistency, reliability, and leaving the railroad in a known condition at the end of each operating day.
