New York City is not a place where you see that many railroad crossings, so it's usually pretty rare when there are instances where crossbucks are needed. One of them is along the east side of the Nereid Avenue, Wakefield-241st, and Dyre Avenue-bound local platform of the <a href="https://en.wikipedia.org/wiki/East_180th_Street_(IRT_White_Plains_Road_Line)" class="extiw" title="w:East 180th Street (IRT White Plains Road Line)">East 180th Street elevated railway station</a> on the <a href="https://en.wikipedia.org/wiki/IRT_White_Plains_Road_Line" class="extiw" title="w:IRT White Plains Road Line">IRT White Plains Road Line</a> in the West Farms section of <a href="https://en.wikipedia.org/wiki/the_Bronx,_New_York_City" class="extiw" title="w:the Bronx, New York City">the Bronx, New York City</a>. The crossing is for a maintenance road and parking space between the tracks and the former East 180th Street <a href="https://en.wikipedia.org/wiki/New_York,_Westchester_and_Boston_Railway" class="extiw" title="w:New York, Westchester and Boston Railway">New York, Westchester and Boston Railway</a> station, which is part of the <a href="https://en.wikipedia.org/wiki/Unionport_Yard" class="extiw" title="w:Unionport Yard">Unionport Yard</a>. Upon cropping of an earlier version of that image, and closer examination, you'll find evidence of a second crossbuck, without the red signals beneath it.
