NSHispeed - The Netherlands
Evacuation test of the "Groene Hart Tunnel" on the new HSL-Zuid high-speed line between Schiphol Airport (Amsterdam) and Rotterdam.
One of the tracks (direction from Rotterdam towards Amsterdam) in the tunnel. You can see about a quarter of the tunnel bore: the tunnel is very wide but divided in two parts for the two tracks. Every 150 meters there are connections from one part to the other.
