NEW YORK A crowded commuter train crashed into an abutment as it was pulling into a New Jersey train station on Sunday, injuring about 40 people.
About 30 people were taken to hospitals and 10 others refused medical attention, police said.
All the injuries appeared to be minor, said John Kelly, spokesman for the Port Authority of New York and New Jersey, which operates the train service.
Roughly 50 people were on board when the train was pulling into the Hoboken, New Jersey station when it slammed into the abutment at about 8:30 a.m.
"Right now it's all under investigation," Kelly said.
"What physically occurred is the train pulling into Hoboken hit the spring bumper, which is the abutment that literally sits at the end of the line," he said.
The train engineer will undergo a drug test as part of the investigation, which he said was standard procedure.
Kelly said it was not clear how fast the train was going when it hit the abutment.
