2 People in Critical Condition in NJ Train Crash

— -- At least 51 people are receiving treatment at Jersey City Medical Center after a New Jersey Transit commuter train crashed into Hoboken Terminal this morning, according to hospital officials.

One woman was killed on the station's platform and at least two people are in critical condition, according to a federal official.

The train’s engineer has been hospitalized with injuries sustained in the crash.

Three people are in serious condition with deep lacerations and orthopedic and internal injuries at Jersey City Medical Center, according to the hospital's CEO Joesph Scott. One of these individuals has been placed in the intensive care unit.

None of these injuries are expected to be life-threatening, according to Kenneth Garay, Jersey City Medical Center's chief medical officer.

Eight people are also being evaluated at the hospital's emergency department for injuries and may be admitted, Scott said. The hospital has set up its cafeteria to accommodate the "walking wounded," he noted.

Officials at the Hoboken University Medical Center, part of the CarePoint Health Medical System, confirmed that they were treating 23 patients for various injuries including lacerations, fractures and bruises, according to the hospital's chief medical officer Meika Roberson.

At least two patients have been operated on, with one person still in surgery, according to hospital officials.

All are in stable condition and no additional patients with serious injuries are expected at this time, according to Roberson.

One patient is being treated for head trauma at Christ Hospital in Jersey City, according to a spokesperson.

Approximately 250 people were on the train that left Spring Valley, New York, at 7:23 a.m. today.

Scott said families wanting to check for missing loved ones can call a hospital hotline at 201-915-2691.

The crash seriously damaged the Hoboken Terminal building, leading to an evacuation. Service on NJ Transit and PATH trains has been suspended.

“There is heavy structural damage to the terminal, which is why it was evacuated," said Jennifer Nelson, director of media relations for NJ Transit. "It is not safe to go in there right now.”
