Engineering Beneath the Surface: How Subways Stay Dry

Explore the hidden world beneath our cities where advanced engineering meets the unrelenting challenge of water. This video delves into the systems and strategies that keep subways from flooding—an essential, but often overlooked, part of urban infrastructure. From waterproof linings to intricate drainage networks and powerful pump stations, you’ll gain a deeper understanding of how engineers battle nature to keep transit systems moving. This journey uncovers how subterranean design adapts to constant threats like rainfall, tidal pressure, and groundwater intrusion.

Using real-world examples, such as the extensive damage and response following Hurricane Sandy’s inundation of New York City’s subway system, the video highlights how critical events have shaped modern flood prevention methods. Watch how engineering teams use lessons from the pa ...
