How does subways work after there’s a flood, is there some warning when it’s flooding, what makes it don’t flood with common rain?


I live in a region where there are no subways nor trains and would like to know about how it works with/prevents floods/rains.

Pumps basically. If the New York subway for example wasn’t constantly maintained with water pumps it would indeed fill up with water.

To quote [this]( article.

>On a dry and sunny day [the head of the NYC Transit Authority’s] department’s 700 or so pumps, at about 280 locations, push 13 million gallons of water out of the subway system and into New York City’s sewers. That’s the equivalent of all the wastewater produced by the city of Boca Raton, Fla., every day.
