In an effort to increase capacity on BNSF Railway Company’s (BNSF) Aberdeen Subdivision in South Dakota, TKDA was commissioned to provide railroad design and construction management services for a track upgrade between Sioux City, Iowa and Aberdeen, South Dakota.
The upgrade included construction of sidings at two locations and the upgrade and extension of an existing siding at a third location along the 160-mile line. The sidings utilized No. 11 turnouts off of the mainline and included switch heaters to facilitate cold weather operations. During the project, TKDA’s track design team coordinated with the BNSF Track Crews and the grading contractor who provided all track bed construction.
