DANNENBERG (AFP) - Thousands of German protesters Friday were preparing demonstrations against a train carrying radioactive nuclear waste from France that has already sparked violent opposition. The train with 11 wagons of reprocessed German nuclear waste crossed the Franco-German border early on Friday and then stopped for more than five hours at the small German town of Neunkirchen to change engines. The train left Neunkirchen just after 4:00 pm (1500 GMT). Television pictures showed police removing half a dozen protesters from the train tracks as they attempted to delay the journey. Everything here is peaceful, people are standing calmly on the bridge, a police spokesman said. #Authorities said they expected less violence than last year when a similar convoy steamed through Germany. But Jochen Stay, a spokesman for the anti-nuclear group Ausgestrahlt (Irradiated), told NTV public television that further attempts would likely be made to block the train as it neared its destination in Gorleben, northeastern Germany. Speaking in Dannenberg, some 20 kilometres (12 miles) from Gorleben, where the waste will be stored, he said: There will of course be action taken to block it when it approaches. People will block the tracks and the roads. But we do not want this to escalate. We want the police to act sensibly and appropriately with people, added Stay. Television pictures showed activists removing ballast stones from under the tracks in a bid to slow the trains progress. Its not about putting the convoy in danger, its about slowing it down for as long as possible or, even better, stopping it altogether, said Hanna Spiegel from activist group Castor Schottern. Late Thursday, police had deployed water cannon and tear gas against a few hundred protesters who tried to block the road near Gorleben. There were a handful of arrests and light injuries on both sides. But the police methods angered the protesters. The police reacted in a completely disproportionate manner. We call on them to use other methods, said one demonstrator, Kerstin Rudek. There were also isolated outbreaks of violence on Friday. An AFP photographer in Metzinger, also near Gorleben, said 10 or so masked people had attacked police with bricks and smoke bombs and managed to escape arrest. Police also said unknown assailants had set two patrol cars on fire. Last November, at the height of a furious debate over nuclear power in Germany, tens of thousands turned out to protest against the shipment, managing to delay the train by a whole day. Activists played a sometimes violent game of cat-and-mouse with police, with stunts including sit-ins, abseiling from bridges into the trains path, removing ballast supporting the tracks and even shepherding sheep and goats into the convoys way. Since then, however, the German government has decided to abandon atomic power in the wake of Marchs nuclear disaster in Fukushima, Japan, and this appeared to have dampened the protests. Organisers have said they were expecting some 20,000 people to protest against the train, fewer than half the number that turned out this time last year. Opposing them was a similar number of police. If smaller in number, the protesters were at least determined. Of course, we would rather do something else than come here every year to spell out the dangers of nuclear waste, but we will put ourselves on the line as often as is needed, said Saskia Kiehling, one of the protesters. The train ran into violent protests soon after leaving its yard operated by French nuclear giant Areva in Valognes, in Normandy, on Wednesday, as it began its 1,100-kilometre journey to Gorleben. Protected by several hundred riot police, the train stopped overnight Thursday at the station of Remilly, just outside the town of Metz in eastern France. It chugged out of there at around 9:00 am (0800 GMT) on Friday. This was expected to be the last such shipment from France, but from 2014, nuclear waste will be transported to Germany from a British processing plant at Sellafield. In June, Chancellor Angela Merkels government agreed to halt all German reactors by 2022, forcing energy suppliers to close the plants. In the meantime, Germany will no longer send nuclear waste for reprocessing in France, but will instead stockpile it until a way is found to make it safe.
