Period: 2009 to 2013
The new Ebensfeld — Erfurt line is part of the German Unity Rail Transport Project No. 8 — Nuremberg — Erfurt — Leipzig/Halle — Berlin upgraded/new line. As a section of the German Unity Transport Project (VDE) No. 8 with the upgraded and new Nuremberg — Erfurt — Leipzig/Halle — Berlin line, the new Ebensfeld — Erfurt line (VDE 8.1) with a total length of approx. 107 km was designed as a standard-gauge, double-track, electrified railroad line for high-quality passenger and freight traffic. The design speed of the Reitersberg Tunnel was therefore also set at 300 km/h. The Reitersberg Tunnel is located within the approximately 5.6 km long Rödental construction section in the district of Coburg. With a total length of 2,975 m, the Reitersberg Tunnel is the fourth longest tunnel of a total of 22 tunnels on the new Ebensfeld — Erfurt line. The Reitersberg tunnel was excavated in units of shell limestone with karst phenomena, Lower Keuper and Upper Buntsandstein.
The tunnel was excavated and blasted. The inner shell, which is up to 90 cm thick, is designed to be pressure-tight. Due to the very short construction time for the inner shell, a “mobile invert bridge” was used. This made it possible to construct a 12.5 m long invert block, including filling concrete, within 2 working days while the tunnelling work continued.
