Project description

The Schanztunnel on railway line no. 4930 Waiblingen – Schwäbisch Hall-Hessental is to be renovated due to the poor structural condition, among other reasons.

The 860 m long Schanztunnel was mined as a two-track tunnel and steined with sandstone building blocks from 1878 to 1880.

However, the tunnel is operated on only a one-track basis with a track installed centrally in the tunnel. The maximum overlay of the tunnel is approximately 90 m.

The single-track line is electrified.

The tunnel lies in the layers of the gypsum Keuper. As a consequence of the water entry into the anhydrite-containing gypsum Keuper, the open sole of the tunnel has risen steadily since its completion.

As part of the advance planning, existing renovation variants with the tunnel-in-tunnel method, with complete closure and with closures in sections as well as replacement construction in a parallel location are to be examined.
