Zurich's new railway tunnel has made exceptionally good going southwards, but now the north end must pass under buildings, sometimes just a few metres down. It will, be difficult work, reports Adrian Greeman. The new Zurich Thalwil tunnel lies on the same high-speed rail route south as the AlpTransit, although it is not part of the project. Eventually it will be part of the Gotthard pass TGV line, since it forms a new fast route out of Zurich's important central station.
