Interlocking: Schaefer Tower, Dearborn, MI
Schaefer Interlocking Tower was located at the crossing of the Michigan Central's Junction Yard branch (Junction Yard to River Rouge) and the DT&I's line to the Ford Rouge complex from near Flat Rock. This tower was staffed by a MC leverman. Over the years it was reduced to day-only staffing and then the location became a radio-controlled electronic interlocking. The tower has been torn down.

"Levermen" operated interlocking towers within the MC Detroit terminal. Levermen did not handle train orders. They took their orders from the MC Detroit yard dispatcher or yardmasters. Schaefer was a fairly simple tower with one leverman on duty. Other towers like West Detroit may have had two levermen on duty on most shifts as well as a "train director" who called out the routes which were lined up on the plant by the leverman. Other leverman towers in Detroit included 15th Street, 20th Street, Bay City Junction, Beaubien and Milwaukee Junction. Pleasant Street (YD), Town Line, North Yard, Trenton (FN) were staffed by "operators" who handled train orders as well as interlocking line ups.
