Michigan Central Tower 2 was one of four interlocking towers east of the Detroit River international tunnel. Tower 2 was located just east of the Windsor station, and controlled switches and crossovers to the Canadian Pacific connection in Windsor.
Tower 2 was replaced by an "NX" interlocking machine operated from the NYC Windsor depot about 1940. [Railway Signaling, 1940-11]
