User:Melkom/City Tunnel

The Frankfurt City Tunnel is standard gauge railway line in the city centre of Frankfurt and the core of the Rhine-Main S-Bahn system.

The line runs completely underground and is divided into two branches south of the Main.

Between Central Station and Konstablerwache
The first part of the tunnel started operation on 28 May 1978. Since then the six original S-Bahn services (S1, S2, S3, S4, S5, S6) enter the tunnel using the western ramp at the former railway post station and reach after 500 m (550 yards) the underground section of the Central Station (Hauptbahnhof). Later the S14 service was included (now S8 and S9).

East of the Central Station the tunnel runs underneath the Wilhelminial style Bahnhofsviertel reaching the Taunusanlage station after 700 m (770 yards).
