With the elimination of the noise and pollution from steam locomotives, this once undesirable section of Park Avenue and the land freed by the burial of the rail yard became prime New York City real estate. The area became one of the city's most attractive residential areas as mansions and high-class apartments were constructed along Park Avenue. The area around Park Avenue in the vicinity of Grand Central was developed into Terminal City. Stretching from 42nd to 51st Streets between Madison and Lexington Avenues, it came to include the Chrysler Building and other prestigious office buildings; luxury apartment houses along Park Avenue; and an array of high-end hotels that included the Marguery, Park Lane, and Waldorf Astoria. The idea to place the rail yard below Park Avenue and construct buildings above it was credited to Wilgus.
