BNSF Tokio to Ritzville Double Track

Location: Adams County, Washington

BNSF Railway's Lakeside Subdivision expansion program expands the current single-track mainline with sidings to a double-track mainline between Spokane and Pasco, Washington. To accomplish this, BNSF is strategically extending existing, controlled siding and double-track segments. DEA provided design, surveying, and construction management services for the 4.5-mile, double-track expansion segment from Ritzville to Tokio, Washington.

The Ritzville-to-Tokio segment extended the old Tokio siding to create a double track. Project success centered on designs that minimized wetland impacts and impacts to train traffic, and a construction approach that controlled construction management costs.

To align a future double-track project through Ritzville, DEA's team designed a transition for new track from the north side to the south side of the existing mainline, and a realignment of the existing mainline just west of the end of the double track. The project extended three culverts and a single road crossing.
