Despite its name BD Tower is actually a ground-level cabin. It was used by the
D&H until the mid 1980's to manage control points in the Binghamton, NY area, including BD and QD
interlockings where D&H tracks crossed (then) Conrail tracks. The structure was removed in the
late 1980's and replaced with an automated relay box which exists to this day and continues to
provide interlocking management for NYS&W, CP, and NS trains. Made by request for the D&H route
being developed by ModelerMJ.
