Mechanical interlocking installed 1892
Interlocking rebuilt 1938

Present interlocking controls CP (former Milwaukee Road) single track over Fox River bridge. Bridge was a gauntlet until 1938, when reconfigured as single track with movable switches. Future plans include double tracking the bridge. Paralleling to the southwest is the Union Pacific (former Chicago & North Western) Belvidere Subdivision. Until 1983, a Chicago & North Western branch diverged north, crossing the Milwaukee Road, and eventually reaching Williams Bay WI. That branch was abandoned south of Crystal Lake, with the remainder north of Crystal Lake evolving to the McHenry Subdivision.
