LIRR Ronkonkoma branch has been restored in both directions between Ronkonkoma and Farmingdale following an earlier disabled tractor-trailer east of Deer Park Station at Executive Drive.
There were residual delays of up to 30 minutes after the incident.
Chopper 12 was over the scene when the stuck tractor-trailer backed off the train tracks.
The MTA advised customers to utilize alternate branches such as the Babylon or Port Jefferson branches.
