Pumps

Keeping Subways Dry

Smooth and reliable service depends on dry train tracks, but dry weather outside doesn't necessarily mean dry conditions on our tracks. Our subway system is mostly underground, and in many areas below the water table so even on a dry day subway pumps remove millions of gallons of water from our system. Water gets to the pumps through drains that run it to pump plants, where pumps then move it into a manhole under the street that empties into the city's storm-water system.

Overall, investments in pumps ensure that our tracks stay dry and our trains run reliably no matter what the weather. But we really get our money's worth on wet days, when subway pumps handle water from overflowing drains in the streets.
