NEW YORK (PIX11)-- A MTA worker touched a third rail with a cable inside the Union Square subway station, sparking an explosion that injured the employee and three others Thursday morning, according to NYC Office Emergency Management.
The transit employee is being treated for second degree burns, officials say.
The worker and two others were sent to New York Hospital. One refused medical treatment.
The explosion caused a smoke condition in the subway and removed everyone from the station.
The 4 and 5 lines will be on the local track south bound.
