Thanks to a tip, movie location scout Nick Carr of Scouting NY set out to see if the Central Union Bus Terminal still exists below Times Square. Located next to what is today Hotel Carter (but was then Hotel Dixie, and apparently a lot less dirty and seedy to boot), it opened around 1930 as the city's largest enclosed coach station. Considering its subterranean nature, the waiting room of what was also known as the Dixie Bus Terminal actually looks kinda classy. Lo and behold, 80-plus years later, some vestiges still remain.
