This used to site at the site of the crossing of the Michigan Central Bay City Branch and the GTW Flint Sub. This structure is now gone. The colors represent early 1970s.This item is freeware. The tower name plates may be reskinned as needed, any further uploads and reskinning must be done with permission only. All uploads only to the DLS.
