More than 15,000 people were issued passes for the first series of rides from the platform. At precisely 2:35 pm, the first subway train departed from City Hall station with Mayor McClellan at the controls. The event was so heavily attended that police Commissioner McAdoo said every policeman in the city was on duty all day and far into the night.
In 1945, the station was closed. The reason was the technological modernization: compositions were replaced by more modern and long, corresponding to the increased passenger traffic. And curved arc platform, City Hall create dangerous gaps between platforms and new doors of transport, and because the loop created an unsafe gap at the platform. Moreover, according to statistics at the time the station capacity no more than 600 people per day. In its final year of use, it served only 600 passengers per day and was not open at nights (when trains continued to the loop station at South Ferry). The Brooklyn Bridge station, located a short walk away, at the opposite end of City Hall Park, was more popular, as it provided both local and express service, including trains to Brooklyn. The Brooklyn Bridge streetcar terminal and Park Row station on the BMT elevated lines were above for easy transfers.
