A Dutch court has upheld a request from German railway company Deutsche Bahn to order internet service provider XS4All to remove documents published by dissident group Radikal.

The group advocates disrupting nuclear waste shipments by cutting overhead power lines on train tracks.

An XS4All spokesman said that Deutsche Bahn wanted to block the home page of one of its users because it contained two 'sabotage' articles from 1996.

Deutsche Bahn said that it also planned to sue search engines Google, AltaVista and Yahoo for providing links to web pages that describe railway sabotage.

AltaVista has agreed to remove the offending page and was surprised to hear that it may be receiving a lawsuit. "We have not received a suit or any threat of legal proceedings from Deutsche Bahn," a spokesman explained.

Google has also cut access to one or two pages cited in Deutsche Bahn's request letter. "We haven't been served with any [lawsuit] that I am aware of," said a spokeswoman. "We're in the process of resolving the matter and we're confident we'll be able to."
