An MTA worker fatally jumped in front of a 6 train in midtown Manhattan yesterday.

MTA maintenance worker Kelly McClain, 45, jumped in front of a northbound 6 train at the 59th Street station near Lexington Avenue around 2:45 p.m. on Friday. The News reports she jumped at the end of the platform, right where the train entered the station. Sources told them she chose "the exact spot where she knew the impact would certainly kill her."

McClain, who was reportedly on duty at the time, had been an MTA employee since 2006. Police add the investigation is ongoing, but no criminality is suspected.
