At Myrdal Station, the Flåm Line runs in the same direction as the trains towards Oslo, but immediately starts running downwards into the Flåmsdalen valley. The first part of the line runs through snow shelters and several short tunnels. Vatnahalsen Station is located from Myrdal, at AMSL. The line then runs through a horseshoe curve and the Vatnahalsen Tunnel. It exits the tunnel onto an artificial shelf on a cliff which falls several hundred meters down. Reinunga Station is located from Myrdal and at elevation. It is followed by Kjosfossen Station, from Myrdal and AMSL, which serves no other purpose than allowing tourists to look at the waterfall Kjosfossen.
