In early 2007, another remnant of the North Shore Line was removed from the Yellow Line. Over the weekend of February 17-18, 2007, Dempster Tower was demolished. The interlocking tower, which stood approximately 300 feet south of the Skokie station platforms, once controlled the junction between the Skokie Valley main line tracks and the spur to the stub platform behind the old Dempster station where Chicago Rapid Transit Niles Center branch "L" trains terminated. The tower was last used in revenue service in March 1948, when the CTA suspended "L" service on the Niles Center branch and the stub platform was no longer used. The masonry tower, whose design complimented the historic Dempster station, stood dormant for the six decades thereafter.
