A subway track supervisor survived a brush with death yesterday, plunging at least 25 feet from the elevated No. 7 line and landing hard but on his feet on the Queens asphalt below.

Just after 11 a.m., Kent Morgan, 50, fell through a fiberglass pathway near 114th Street and Roosevelt Avenue in Corona.

The 28-year veteran track worker, a married father of two, crumpled onto his right side upon impact, and his head pounded the sidewalk, sending his white helmet flying down the street, witnesses said.

“He couldn’t talk,” said car-service dispatcher Luis Lopez, 31.

Paramedics took Morgan, of East Stroudsburg, Pa., to New York Hospital Queens in Flushing, where he underwent emergency surgery on multiple fractures. He was alert later, but doctors said he’d need more surgery.

An NYC Transit spokesperson said the cause of the fall was under investigation.
