MTA Explores New Cooling System For Underground Subway Stations

By Y.M. Lowy

The MTA is studying new technology that could help cool down New York City’s hot subway platforms in the summer. They will begin using geothermal systems, which use the ground to move and store heat. The idea is to take heat from deep underground stations and push it further below the surface. The goal would be to keep stations between 82 and 85 degrees on hot days.

The first stations being considered are 168th Street and 181st Street on the 1 line. Both are more than 100 feet below ground and stay especially warm in the summer. On a recent day when it was 75 degrees above ground, riders at those stations were visibly sweating as they waited for trains.

The project would require drilling and installing pipes far underground, which would take significant work. For now, the MTA is asking for ideas and information from experts before deciding if the plan is possible.
