Subways are usually built under city streets for ease of construction, but they may take shortcuts and sometimes must pass under rivers. Outlying sections of the system usually emerge aboveground, becoming conventional railways or elevated transit lines.

Where does the water go when the subway floods?

As rainwater seeps through tunnel walls and flows down subway grates and stairwells, sump pumps in 280 pump rooms next to the subway tracks pull the water back up to street level. That water then naturally flows toward the storm drains — but the storm drains themselves are often unable to handle the flow of water.
