A nearly five-mile second main line track between Washougal and Mt. Pleasant, Wash. was recently completed, with a first train successfully travelling over the line near the BNSF’s Fallbridge Subdivision, which spans the Columbia River Gorge, late in December 2018. Adding a second track addresses previous constraints on the west end of the subdivision, enhancing capacity and improving traffic flow throughout this region.
Grading for the new line started in June 2018. The BNSF Engineering team built the second main track by relaying two miles of the existing siding and constructing 2.3 miles of new track. One steel bridge and three retaining walls were also constructed for the second main line.
