City tunnel
The city tunnel is an underground, pure S-Bahn route used by almost all services.History
The S6 was one of the first six services of the Rhine-Main S-Bahn system. In a prior test operation it ran between Kronberg and Frankfurt Central Station. The service was then called R6 where the letter "R" stands for regional. After the opening of the Frankfurt Citytunnel the service was renamed to S6 and extended to the new Hauptwache underground station. Further extensions of the tunnel followed in 1983 and 1990 so that Stresemannallee became the service's eastern terminal.Operation
