The new tunnel in Buir on the upgraded line Cologne-Düren
(<a href="http://www-users.rwth-aachen.de/christoph.schmitz2/strecke/strecke.html">ABS 4</a>)
seen from west on 8 December 2001. The highspeed tracks on it seem to be more
or less finished, also the catenary of the northern track is already present.
When the old tracks on the right are out of service, the tunnel can be
continued. After this the old level crossing in the background will be removed.
