From NBC's website:
Long Island Rail Road customers are being advised to expect delays and cancellations on nearly all branches after a NY & Atlantic Railway freight train derailed at Jamaica Station.
With the exception of the Port Washington branch, all lines on the LIRR are experiencing service delays, according to the MTA website.
A LIRR spokesman said a NY & Atlantic Railway was moving west into Jamaica station when the last three cars derailed just east of the station.
The derailed train is blocking one track, but seven others remain clear. LIRR trains will be running on those tracks, but customers should expect delays, spokesman Salvatore Arena said.
NY & Atlantic Railway uses LIRR-owned tracks to deliver commodities through Long Island, according to its parent company's website.
