A man was dragged to his death after a shoulder bag he was carrying got caught in a moving subway train in Midtown on Tuesday night, police sources said.

The 39-year-old man from Queens was standing on the eastbound No. 7 train platform at Grand Central Terminal at about 7:20 p.m. when his bag got caught by a train that was pulling out of the station, the sources said.

It’s not clear if the man’s bag was caught on the doors of the train or another part of the subway car.

The train then dragged him off the platform and onto the tracks, pulling him into a staircase and an electrical control box, according to police sources.

Police are investigating whether the man was intoxicated when he was dragged to his death.
