 One of the tracks to be regraded was the line paralleling St. Aubin.These tracks ran from the northwest, where they connected with a network of other lines, to the southeast, where the tracks turned to parallel the river and supplied a number of large factories, including the Detroit-Michigan Stove Plant, the United States Rubber Company Plant, and the Parke-Davis Laboratories.The tracks terminated at the Brush Street Depot in downtown Detroit.
