7. The Reason City Hall Subway Station is No Longer in Use
The City Hall Subway station is located just 600 feet south of the current Brooklyn Bridge/City Hall station where the 4/5/6 and J/M/Z trains operate from. The station is 400 feet long along a curve without any straight lines of sight. The original City Hall subway station was closed in 1945 because its curved platform wasn’t able to accommodate the IRT’s newer, longer cars without extensive renovation. Today, the station is used as a turnaround for the 6 trains after they terminate at the Brooklyn Bridge stop.
