Northern portal of the Unterwald-tunnel between Kalwang and Wald am Schoberpass. 
This section is actually being double-tracked and also the alignment is being improved to allow higher speeds.
The section is due to open in late 2003. The picture has been taken from a train (IC 512) running on the old track.
