A 65-year-old man is clinging to life after police believe he accidentally fell onto the tracks at a Queens subway station on Monday afternoon.

The man tumbled onto the southbound 7 train track at the Queensboro Plaza station around 3:30 p.m. and was taken to Bellevue in a critical condition, police said.

Police say no criminality is suspected and that it appears the man simply lost his balance.

An investigation into the incident is ongoing.

The fall caused delays on Manhattan-bound 7 trains.

The Post has contacted the MTA for further comment.
