Long Island Rail Road service between Greenport and Ronkonkoma is suspended after two trains pulling a freight train derailed early Friday morning, the railroad said.

Don Miller, spokesman for the New York & Atlantic Railway — the freight provider that operates on the LIRR’s tracks — said a freight train with seven empty cars and two locomotives traveling westbound derailed just west of the crossing at Knickerbocker Avenue in Ronkonkoma, east of the Ronkonkoma LIRR station.

The incident happened around 3 a.m., the Metropolitan Transportation Authority said.

Miller said shortly before noon Friday that an investigation into the cause is underway.

“At no time did this event cause any risk to the public,” Miller said. “Company teams were quickly dispatched and repairs have begun.”

Buses have replaced trains between Ronkonkoma and Greenport, MTA officials said. Customers at stations east of Ronkonkoma are advised to use alternate branches or other modes of transportation.

As of 1:26 p.m., the MTA said one of the two locomotives had been "re-railed."

“Crews are on scene working to move the freight train from the area,” the railroad said Friday afternoon.
