Eventually economic development led to the need for further rail activity on the sparsely used Tacoma Eastern. The Boeing Company, with plants all along Puget Sound, finally submitted to political pressure at the Federal, State and local levels to site a production facility in Pierce County. Frederickson, a station on the old Tacoma Eastern line, was chosen as the preferred location. Here the Boeing Company constructed a massive aircraft wing assembly plant. The Weyerhaeuser Corporation had no interest in restructuring its railroad for common carrier service, but did allow a subcontractor to operate on 12 miles of track from Tacoma Junction to Frederickson. Until 1998, rail operations by the contractor were commonly referred to as simply the Boeing Train. Weyerhaeuser ceased all rail operations in the south Puget Sound basin by 1992 and began selling off segments of the former Tacoma Eastern Railroad to the City of Tacoma.
