Prague  - A Polish woman, a Ukrainian man and three Czechs were among the seven victims of Friday's train accident in eastern Czech Republic, the worst in 13 years, police said Saturday.

Revising its earlier reports, police said that four young women and two men, one young and one middle-aged, died when a speeding international train with some 400 passengers onboard rammed into a collapsed bridge in the north-eastern town of Studenka.

Another passenger, a Ukrainian man, later succumbed to injuries in a hospital, police spokeswoman Miroslava Michalkova Salkova told Deutsche Presse-Agentur dpa.

One female victim was Czech and one Polish, while the identities of two women remain unknown, she said. Both men killed at the scene were Czech.

In all 67 passengers were treated in local hospitals, including the Ukrainian victim, two French nationals, two Slovaks and 13 Poles, firefighters said.

The deadly crash has paralyzed rail traffic on the main track between Austria and Poland as well as between the Czech Republic and Poland and parts of Slovakia. Trains are running on detour routes with delays.

"In a very optimistic outlook we will be able to restore partial service Monday," Czech Railways spokesman Petr Stahlavsky told dpa.

He said that relentless rain at the scene Saturday was complicating police and railway investigation as well as cleanup work.

Three cranes and two tanks were brought to the scene to help remove the wreckage, including the engine that weighs some 90 tons, he said.

The engine and four cars of a 10-car Eurocity train bound from the Polish tourist destination of Krakow to the Czech capital Prague flew off the tracks when the bridge's concrete deck reinforced by steel beams fell onto the tracks in in front of it.

The engine driver, who survived the blast with slight injuries, noticed that the deck had "swung". The bridge was under reconstruction at the time of the tragedy.

The driver applied fast-acting brakes, slowing the train from 133 kilometres per hour to 90 kilometres per hour at the time of the crash, railway inspectors said citing the engine data.

Three cargo cars standing stationary on a side track were also derailed in the impact. The resulting railway damage is estimated at 136 million koruny (8.4 million dollars).

It was the Czech Republic's worst train accident in 13 years, after 19 died when a local passenger train slammed into cargo cars by the eastern Bohemian village of Krouna in June 1995. (dpa)
