DEER PARK - Officials say a Long Island Rail Road train slammed into a truck this morning, killing the driver and suspending service on the Ronkonkoma line earlier today.

The incident happened just after 6:40 a.m. at the eastern end of the Deer Park train station near the Executive Drive crossing.

Authorities say Ahmad Karimzada was trying to drive around the crossing gates. He was killed instantly.

LIRR passenger Melvin Yee, of St. James, says he was jolted by the crash and saw through the window that the white truck was about 5-10 feet up in the air.

Officials say one person on the train that was carrying about 300 people suffered a shoulder fracture in the collision. There was also damage to the crossing gate, the signal and the third rail.

Trains were suspended between Ronkonkoma and Farmingdale and were replaced by buses throughout the morning and afternoon while crews were removing debris from the tracks.
