Station: South Adrian, MI (Wabash/DT&I) Interlocker
Michigan's Internet Railroad History Museum
South
Adrian is located south of the City of Adrian and was a crossing of the
Detroit & Lima Northern and the Wabash Railroad. The interlocker
plan at the right is from October 29, 1900.
In 1924, the interlocker was changed and 4 electromechanical levers were added to the tower. The wye track was removed and a new center interchange track was added (see second diagram below). In 1926 the Wabash double-tracked its main line through Adrian.
In 1930, the tower was removed and replaced by a cabin interlocker. The leverman assigned to the tower was reassigned. The interlocker was now changed by DT&I crews that required passage. At this point, the route received only one train each way per day according to Michigan Railroad Commission plans.
In June, 1932, the approach signals were changed from controlled to fixed-approach. In 1936, the Wabash eliminated a crossover between their two main tracks which had been controlled.
In June, 1941, the cabin was removed and the interlocker was automated. Stop boards and signals were placed on the DT&I, and new signals were installed on the Wabash.
