OLMSTED FALLS, Ohio (AP) _ A man stabbed three people aboard an Amtrak train outside Cleveland early today, then was wounded himself as passengers wrested the knife from him, police said.

Police said the man went through three cars of the Lakeshore Limited, stabbing people. Two of the victims were conductors, a dispatcher said.

Jessica Franz, 17, of Detroit was asleep when a wounded conductor stumbled into her compartment and fell.

``It was such a shock,'' said Franz, who was on her way to school at Smith College. ``I'm just glad it's over.''

The Lakeshore Limited, which runs daily between Chicago and New York, was approaching Cleveland when the stabbings occurred about 3:20 a.m., police Lt. John Minek said.

A conductor ordered the train stopped in Olmsted Falls, 14 miles southwest of Cleveland, and the assailant, who was not identified, surrendered when police arrived, Minek said.

He said the attacker apparently didn't know any of the victims.

Two men, aged 26 and 52, were in stable condition at Cleveland MetroHealth Medical Center and two more people were at St. John West Shore Hospital in suburban Westlake, according to nursing supervisors who would not give their names. No further information was given.

Minek said one of those taken to St. John was believed to be the suspect, whose left hand was severely cut.

The train carried 330 people, and the other passengers were put on buses to be taken to Cleveland.

Jackie Mallory, 50, of Chicago was still shaking when she stepped off the train for the bus trip.

``It's been a long night,'' she said.
