Interlocking: Center Street Tower, Bay City, MI

Bay City Center Street InterlockingB&O Coal Train at Center Street Bay CityCenter Street Interlocking in Bay City protected the crossing of the Michigan Central Bay City Branch and the Pere Marquette/C&O Belt Line to Essexville. Originally operated from a tower in the northeast quadrant of the crossing, it also controlled the Detroit, Bay City and Western railroad which was a late comer to the area. At some point after the DBC&W was removed, the crossing was converted to an automatic interlocking and the tower removed.
