Location: Cadillac, MI - GR&I/AA Crossing
The Grand Rapids & Indiana railroad was crossed in downtown Cadillac by the Ann Arbor railroad at a crossing located south of Chapin, just east of the lake. In later years, this crossing was an automatic interlocker with PRR-style signals on the former GR&I.

Notes
This crossing was controlled by a 2-story interlocking tower (see photo). The tower had a mechanical interlocking machine with eight levers. Five levers were for five signals, and one lever was the master lever. There were two spare levers (#4 and #6).
This was also a GR&I/PRR block station and was open around the clock.
The tower was in the southeast quadrant of the crossing.
