Interlocking: Diann Tower, Dundee, MI

Diann MI Interlocking TowerDiann was an interlocked grade crossing of the Ann Arbor railroad main line (Toledo to Frankfort) and the Detroit, Toledo & Ironton railroad main line (Detroit to Ironton, OH) in Dundee Township about two miles south of the village of Dundee.

This crossing was created during Ford ownership of the DT&I and the main line was rerouted at the Malinta cut-off. Ford built a sturdy electromechanical interlocking tower here, as well as a connection for both lines on the northwest and southeast quadrants. Both lines were block signaled at this location.

This was one of the last new interlocking tower locations in Michigan.
