High Speed Train Tunnel

The ICE (InterCityExpress) is the fastest train in Germany (300 km/h). The 2 tracks in this 4.5 km long tunnel are especially built for the ICE.  I had the rare opportunity to shoot the pictures after midnight when regular traffic pauses for 3 hours.

Caution: Light at the end of a tunnel sometimes are the headlights of an approaching train. (Bertrand Russel)
