How do NYC subways not flood?
Housed at the street level above the stairwells that lead down into the stations, the floodgates are made of a Kevlar-based fabric that can be rolled out horizontally ahead of flood events to create a kind of lid over the openings.

Can trains drive through floods?
Sometimes flood water doesn’t stop trains running, but if water levels rise above the rails, trains have to reduce their speed to prevent damage to the train, which in turn can cause delays.
How does the London Underground not flood?
At least 170 pump controller units are installed across the London Underground, gathering data and being remotely operated when needed to alleviate the impact of flooding. And most of the stations situated on the flood plain have had flood doors installed.
How do subways help the environment?
Many turn to the construction of mass rapid transit systems in the hope of reducing the use of cars and motorcycles and the pollution they cause. The logic of why subways might reduce air pollution is straightforward: substituting trips using fossil fuel-burning vehicles for trips on subways reduces emissions.
What powers do subways have?
Direct current (DC) is used to operate trains and such auxiliary equipment as water pumps and emergency lighting. The system’s 214 electrical-power substations receive high and low-voltage electrical current from the New York Power Authority.
