The Silberberg railway tunnel in the Thuringian Forest is part of the new Ebensfeld – Erfurt railway line. The new line connects the old and the new federal states.
During the construction of the Vienna underground line 2 extensive dewatering works with approx. 270 wells and approx. six million pumping hours were required. An electronic monitoring and control system made the measure safe.
Due to an advantageous layout of tunnel portal and tunnel excavator is was possible to do without shunting bays and laborious shunting during the construction of the single-track railway tunnel.
