Web-based construction progress
Updated every morning, it shows the positions of our tunnel boring machines. The first one is already in operation, the second will be joining in at the beginning of 2011. In addition, the percentage of the tunnels already completed is shown on every single page of www.xfel.eu.
In other words: progress is now visible everywhere.
