The mission of the GTW Historical Society is to preserve and record the history of the lines, facilities, equipment, and personnel of the GTW Railroad, it’s subsidiaries, predecessors, and successors, including the GTW, DT&I, D&TSL, and Detroit Terminal railroads. We also may cover the rail operations and equipment of shippers and subcontractors, such as Detroit Edison, SEMTA, and Amtrak, as they relate to the GTW. We endeavor to record and publish information of a historical and educational nature in print and electronic format, principally via our quarterly newsletter, The Semaphore. Our publications are intended to appeal to railfans and railroad historians, retired and active railroad employees, model railroad hobbyists, and others with similar interests.
