In 2004, OmniTRAX leased to purchase the eastern fork, and purchased the western fork, from BNSF, while having running rights on the Chewelah–Kettle Falls section. In 2006, the KFR abandoned the San Poil–
Danville section. It is unclear whether the rails across the border were removed at this time or during the subsequent years. In 2019, the St. Paul & Pacific Northwest Railroad (STPP) acquired the Chewelah–Columbia Gardens section. Initial interlining was with BNSF to the south at Chewelah and Kettle Falls,
Grand Forks Railway (GFR) to the northwest at Grand Forks, and
International Rail Road Systems (IRRS) to the northeast at Columbia Gardens. After the 2019 STPP acquisition, two KFR interlines remained, a new one with STPP at Kettle Falls, ==Footnotes==
