SM Signal Station
Most railroads called buildings with interlocking equipment "towers". The New York Central term was "signal station", though many people called them towers anyway.
SM Tower was located at the east end of the Alfred H. Smith Memorial bridge and routed trains eastward on the Boston & Albany or south to the Hudson Division and to New York City.
As of 2020, the lower half of the building was still standing, having at one point been converted to house electrical panels.
Our building was modified from a kit offered by the New York Central System Historical Society. The N-Scale Architect made the kit for the society. It is shown at a temporary location on the layout.
