Early Tuesday morning, an M.T.A. track worker died after falling from a perch inside the tunnel that carries the 4/5/6 trains near 125 Street in Harlem.
St. Clair Ziare Richards-Stephens, 23, died at the scene, according to the police.
Mr. Richards-Stephens was performing track maintenance, when he fell through the wood railing lining the tunnel, and landed on his head. He had only been working at New York City Transit for six months.
“These are the days you dread,” said Andy Byford, president of New York City Transit.
Tony Utano, president of Transport Workers Union Local 100, which represents thousands of M.T.A. employees, noted that “this is a sad day for transit workers.”
Both men promised a full investigation into what went wrong, and led to Richards-Stephens’ death.
