The subway system is "in jeopardy," MTA Chairman Joseph Lhota said Monday. "Our subway system and salt water do not mix."
Salt can eat at motors, metal fasteners and the electronic parts, some many decades old, that keep the system running. Salt water, and the deposits it leaves behind, degrades the relays that run the signal system, preventing train collisions. Salt water also conducts electricity, which can exacerbate damage to signals if the system isn't powered down before a flood.
I can explain it to you but I can't understand it for you.

"Now, more than ever, the illusions of division threaten our very existence. We all know the truth: more connects us than separates us. But in times of crisis the wise build bridges, while the foolish build barriers. We must find a way to look after one another as if we were one single tribe.” -King T'Challa, Black Panther
The truth is incontrovertible. Malice may attack it. ignorance may deride it, but in the end, there it is. ~Winston Churchill
