BURGRAIN, GERMANY (AFP) - The death toll from a German train derailment near a Bavarian Alpine resort climbed to five on Saturday (June 4) as a further body was recovered from the wreckage, police said.

Investigators were combing the overturned carriages for victims and clues as to the cause of Friday's accident near Garmisch-Partenkirchen, a region gearing up to host the Group of Seven summit in late June.

"At the moment we do not believe there were further victims, but I cannot yet say for sure," regional deputy police chief Frank Hellwig told reporters.

He said four of the dead were women, with another 44 people injured, some of them children.

The accident occurred just after midday on Friday as school holidays were starting in the two southern German regions Baden-Wuerttemberg and Bavaria.

Police said the regional train was "very crowded" with about 140 people on board as a new €9 (S$13) monthly public transport ticket valid across Germany also boosted demand.

Federal transport minister Volker Wissing visited the site of the accident on Saturday, saying he was "very moved" to see the "dramatic" extent of the damage.

"We will continue to investigate and get to the bottom of what happened," he told reporters.

The head of the German rail company Deutsche Bahn, Mr Richard Lutz, also at the scene of the crash, said he was "saddened" by the deaths and pledged a thorough probe.

The train had just left popular mountain resort Garmisch-Partenkirchen for the Bavarian state capital Munich when the accident took place in the Burgrain district.

The region has begun preparations to host the G-7 summit of world leaders later this month. From June 26-28, the heads of state and government including United Sates President Joe Biden are due to meet at Schloss Elmau - 11km from Garmisch-Partenkirchen.
