S26 Ep5: Constructing Pennsylvania Station
Video duration: 1:35
Over 500 buildings were initially cleared for Penn Stations construction, an area equal to two city blocks, or 28 acres. Crews worked day and night to build the train yard below ground, excavating tons of earth from the construction site. Avenues, buildings, and elevated railroads around the construction had to be propped up while workers excavated around the underground infrastructure.
