A passenger train hit a trailer at a crossing in northern Japan and derailed Tuesday, injuring at least one person, police said.

The driver of the trailer was slightly hurt, and the first car of the express passenger train derailed, said Takayuki Muto, spokesman for Ibaraki Prefectural Police (search). There were no immediate reports of additional injuries.

The trailer was stalled at the crossing after one of the wheels came off. The driver of the trailer pulled an emergency alarm at the crossing, but the train was unable to stop in time, Muto said.

No further details were immediately available.

The reported accident in Nimori (search), 50 miles northeast of Tokyo (search), came a day after a major train wreck in western Japan killed 73 people.
