If the Chambers Street overhaul proceeds, MTA will fast-track similar thermal pilots at other extreme-heat stations.
Transit heat is becoming a frontline climate and public-health issue; a successful pilot could set a template for retrofits across major U.S. systems.

Curated summary
New York City officials announced a study with the MTA to test a thermal energy network at the Brooklyn Bridge-City Hall and Chambers Street subway complex. Officials said the project would cool platforms, store excess heat underground, and redirect it to nearby city buildings during colder months. The MTA said Brooklyn Bridge-City Hall is among the system’s hottest stations, averaging 96°F in summer 2025, and the study is tied to a major overhaul of the aging Chambers Street station.
