Interlocking: Beaubien Street Tower, Detroit, MI
Beaubien Street Tower was located on the Bay City Branch at Beaubien Street in Detroit's new center area. This tower was located between Spring Works and Milwaukee Junction on the MC, and between the Amtrak station and West Detroit on the GTW. The double-track MC line crossed the Grand Trunk Western branch here.
Photo info/credit: Top, the Michigan Central Beaubien Tower, as photographed in 1986. The tower was unusual in that it had "moveable point diamonds", which were a necessity due to the severe angle of the diamond crossings. Normal open diamond points would have led to derailments. In the above photo, a southbound Grand Trunk engine set heads towards West Detroit. 2nd photo, taken in a north direction and provides a full view of the tower. [Both, Charlie Whipp]
