In just the last few weeks, the city's subway system has been completely inundated by rain multiple times, including on Wednesday night, when most trains were brought to a complete halt.

And nearly nine years after Hurricane Sandy devastated much of the city, the recent storms show how the system still remains incredibly vulnerable.

Sarah Kaufman, the Associate Director for the NYU Rudin Center for Transportation, joined anchor Errol Louis on “Inside City Hall” on Thursday to talk about what the MTA needs to do to make sure the subway system is climate resilient.
