One person was hurt, and another was killed, during unrelated subway incidents overnight, police said Saturday.

A homeless man was fatally struck by the shuttle train at Grand Central Station around 11:35 p.m. on Friday, police and FDNY spokespersons said.

The victim, who was approximately in his 50s, was on the tracks when he was struck by the eastbound train.

He was rushed to Bellevue Hospital Center, but could not be saved. Police said they do not suspect any criminality was involved.

A second man was injured when he fell underneath a southbound F train around 3:45 a.m. Saturday while walking between cars in Brooklyn, cops said.

The 34-year-old hurt his head and left knee when he fell from the subway as it was rolling into York Street station.

He was taken to Bellevue with non-life threatening injuries, according to authorities.
