Grand Central Terminal Station 100th Anniversary, New York City, United States

Between 1903 and 1913, the entire building was torn down in phases and replaced by the current Grand Central Terminal, which was designed by the architectural firms of Reed and Stem and Warren and Wetmore, who entered an agreement to act as the associated architects of Grand Central Terminal in February 1904. Reed & Stem were responsible for the overall design of the station, Warren and Wetmore added architectural details and the Beaux-Arts style. Charles Reed was appointed the chief executive for the collaboration between the two firms, and promptly appointed Alfred T. Fellheimer as head of the combined design team. This work was accompanied by the electrification of the three railroads using the station and the burial of the approach in the Park Avenue tunnel. The result of this was the creation of several blocks worth of prime real estate in Manhattan, which were then sold for a large sum of money. The new terminal opened on February 2, 1913.
French sculptor Jules-Alexis Coutan created what was, at the time of its unveiling in 1914, considered the largest sculptural group in the world. It is 48 feet (15 m) high, the clock in the center having a circumference of 13 feet (4.0 m). It depicts Mercury flanked by Hercules and Minerva and was carved by the John Donnelly Company.

To accommodate ever-growing rail traffic into the restricted Midtown area, William J. Wilgus, chief engineer of the New York Central Railroad took advantage of the recent electrification technology to propose a novel scheme: a bi-level station below ground.
