A woman died when a train inside a Queens subway station struck her head, police said.

The victim, whose name and age were not immediately available, was standing on the N and W line platform of the 30th Avenue Station in Astoria around 2 p.m. Thursday when her head was hit by a passing train, causing a “severe head injury,” police said.

The victim was rushed to Mount Sinai Queens, but she died.

“@NYCTSubway let people know N service is down cause the train I was on hit a woman at 30th ave,” wrote Twitter user @MTAIhatethe. “It was a gruesome scene.”

“The conductor was screaming and crying as were everyone on the platform and in the cars. What a sad day.”

N trains are running with delays in both directions, according to a NYCT tweet.
