Substation 7

You are standing before Substation 7, a structure that helped pull New York City into the electric age. Built in 1901, its original purpose was to convert high-voltage electricity into the direct current needed to power the massive elevated trains that once rattled through the city streets. At the time of its construction, this neighborhood was a dense hub of immigrant life, and the station’s imposing granite and brick design was built to blend in with, yet stand apart from, the surrounding tenement blocks. Look closely at the facade and you can still see the faint, ghosted lettering of the Manhattan Railway Company, the original operator of the elevated lines. While the loud, steam-powered trains and their original tracks have long since vanished from the streetscape above, this building remained vital. From 1918 through the late twentieth century, it served as a primary power source for the Lexington Avenue subway line that runs deep underground. Today, it remains under the ownership of the transit authority and continues to function as a specialized maintenance facility. It stands as the only substation in Manhattan from that pioneering era of electrification that still retains its original outward appearance.
