UPPER EAST SIDE -- A young woman was struck and killed Wednesday by a subway train at the East 77th Street station on the Lexington Avenue line, authorities said.
Police said the woman in her 20s fainted or had a seizure and fell into the path of a northbound 6 train in the Lexington Ave. station just after 3 p.m.
The woman was not identified.
Fire officials said a second person fainted and was taken to Lenox Hill Hospital.
Subway officials cut off northbound service on the No. 6 line between Grand Central Terminal and E. 86th Street in the wake of the accident.
Evelyn Carbonell of the Lower East SIde said she was jolted when the train came to a sudden halt.
"I heard something go 'boom.' I looked across [on the platform] and everyone had their hands over their mouths," said Carbonell, 50.
Shaq Crudup was heading home to the Bronx when she felt a massive "thump."
"You could feel it -- I thought someone was shooting a shotgun," said Crudup, 31.
Officials said the train involved was a 6 train, but several passengers said it was actually a 5 train running on the local line.
