open construction site day

At the new underground railway station that is placed exactly under the existing railway station. Huge impressive halls bigger than Bern's cathedral. This is 'only' one of four tunnels leading to the two main halls. Hard to imagine: All the construction works are executed under full operation of the station, only two tracks at a time are closed. I will post more pics later tonight on Instagram.
