CASTELBELLO, Italy (AFP) — A landslide swept a passenger train off the rails in mountainous northern Italy yesterday, killing nine people and injuring 28, and leaving one car dangling precariously over the Adige river.

The regional three-carriage train came off the rails at around 9:00 am when the landslide hit the front passenger car near the city of Bolzano, a rescue official said.

Seven seriously injured people were hospitalised.

The toll, which was revised down from 11 because of an error, is not final, since “there could still be someone buried in the mud,” said Bolzano provincial governor Luis Durnwalder, quoted by the ANSA news agency.

Another train had passed in the other direction without incident just two minutes before the landslide struck in the rugged mountain area, he said.

“The operation posed immediate difficulties given that the first car was dangling between the rails and the Adige River… and the second was invaded by mud and debris,” he added.

The front car of the train lodged between two large trees which stopped it from falling into the river below between the towns of Laces and Castelbello.

The wagon was left hanging precariously over the river and firefighters used cables to prevent it from slipping further down the mountainside.

Rescue workers had to climb up from the forested riverbank to reach the train, comprising a passenger carriage at each end and a locomotive in the middle.

The some 400 cubic metres of mud covered around 15 metres of track, according to a local geologist, Ludwig Noessing.

A field hospital was set up nearby, media reports said.

“We are speechless over this catastrophe, whose magnitude and causes are not completely clear yet,” the head of the Bolzano provincial council, Dieter Steger, said in a statement.

Consumer advocacy group Codacons, calling the accident “a massacre of innocents,” demanded an investigation into any “omissions or neglect on safety or maintenance over the entire rail line.”

Police have located the train’s badly damaged “black box,” reports said.

According to a preliminary reconstruction, the landslide was caused by a broken irrigation pipe in a field above the rails, “drenching the terrain below,” a provincial spokesman told Italian television.

The railway line, inaugurated in 2005, is considered one of the most modern in the country.

Italian Transport Minister Altero Matteoli expressed “condolences to the victims families”, but refused to make any “hypothesis about responsibilities for the cause.”

Prosecutors in Bolzano have opened an investigation.
