A subway cleaner was killed Thursday when he fell between the tracks at a train yard in the Bronx, police said.

The 40-year-old man was trying to cross the tracks at the East 239th Street train yard in the Wakefield section at about 5 a.m. when he fell, police said. He was pronounced dead at the scene.

The city medical examiner�s office will determine the cause of the man�s death. His name was not released.

The normally 24-hour subway system has been closed for cleaning and disinfecting between 1 a.m. and 5 a.m. since May 6 in an effort to contain the spread of the coronavirus.
