Long Island Rail Road officials said service on the Ronkonkoma line is "back on track" 15 hours after a train slammed into a car in East Farmingdale last night.

One person in the car was killed in the crash west of the Pinelawn Station around 8:30 p.m. Transit officials were unable to confirm if anyone else was in the car.

The crash caused extensive damage to the running rail, third rail and signal infrastructure, according to Long Island Rail Road President Rob Free.

"All indications we have from the preliminary investigation are the crossing gates were operating as intended and that's through camera views and event recorders at the crossing itself, the vehicle stopped on the tracks," Free said.

Free added that the train was going between 75 and 80 mph in an 80 mph zone at the time of the collision and that all safety features were working.

"It's a reminder to the public of the dangers of the crossings, to adhere to the crossing gates when they're working, they're flashing and the gates are coming down," he said. "They must adhere to those gates, stop and let train traffic proceed."

The crash forced the Metropolitan Transportation Authority to partially shut down service between 8:30 p.m. Thursday and 3 a.m. Friday between Ronkonkoma and Farmingdale.

Partial service resumed with delays and cancellations until about 11 a.m. today as workers repaired the damage.

The crash forced commuters to take different trains, with some people waiting on the platform for longer than usual or having to arrive early.

"I normally like to dress a little late, move a little late, so now I had to move a little extra early," Farmingdale resident Liselle Powder said.

"I'm trying to get to work, so now I've got to add another step, so it just makes it a little worse commute," Amityville's Anthony Gonzalez said as his usual train to Atlantic Terminal was canceled.

Witnesses said the crash left the silver car totaled, burning and trapped underneath the front of the train.

"All of a sudden, I just heard a loud boom," Farmingdale resident Ahmed Khan said. "I thought it was a loud explosion."

No one on the train was injured.

The investigation into how the car got past the crossing guard arms and onto the tracks is ongoing.
