The 159th Street Yard, ca. 1945.

Just north of the Polo Grounds, the 159th Street Yard served the Ninth Avenue El until its closure in 1940. By 1942, the city was accepting bids for the yard to be dismantled, and for its scrap metal to be salvaged for the war effort. Eventually, the yard was cleared for the construction of the Colonial Park Houses (now the NYCHA Ralph Rangel Houses) between 1948-51.
