Rensselaer and Saratoga Railroad: Green Island Shops

The Rensselaer and Saratoga Railroad: Green Island Shops were two historic buildings and one historic structure located at Green Island, Albany County, New York. The buildings were built in 1871 by the Rensselaer and Saratoga Railroad. They are: the three-story, five-bay, brick car shop building measuring approximately 100 by; the one-story, semicircular, brick roundhouse; and the 40 ft octagonal water tower. The shops remained in operation into the late 1930s.

It was added to the National Register of Historic Places in 1973.

On March 3, 2011 the structure caught fire. The fire started on the third floor and quickly spread to the first. The building was demolished a few weeks later.
