Protesters opposed to Germany’s Stuttgart 21 rail project have taken their battle to Berlin.
Activists gathered outside the HQ of state rail operator Deutsche Bahn.
A high-speed train line is planned to link Paris to Budapest through Stuttgart.
If the project goes ahead, the city’s train station will be rebuilt.
Opponents say it will destroy the local landscape and will be too expensive.
Chancellor Angela Merkel’s support for the scheme could cost her Christian Democrat party dear.
Next March, the CDU faces a regional election in Baden-Württemberg, which counts Stuttgart as its capital.
It’s been a centre-right stronghold since 1953 but polls show CDU support is ebbing away.
