First responders rushed to Park Street shortly after 5 p.m. The man did not come in contact with the third rail, but was knocked unconscious.

Power was shut on the southbound tracks to let firefighters safely get him ready for transport to a local hospital. He was brought upstairs and handed over to EMTs around 5:40 p.m. BFD gave the OK to the T to turn the power back on, as people continued to pour into Red Line stations at rush hour.

Park Street itself became so overcrowded that, as a BFD commander was leaving the scene, he asked the T to turn on fans in the station to try to reduce the sweltering conditions.
