Service on the Long Island Rail Road's Long Beach branch was temporarily suspended in both directions after MTA police say a train struck a man at the Lynbrook station Thursday night.
The victim was initially alive but News 12 has learned he was pronounced dead.
The LIRR also tweeted that some eastbound Long Beach trains were being rerouted to Freeport, with added stops at Rockville Centre and Baldwin.
It was not immediately clear when service would be restored.
