Rosensteintunnel

Rosenstein tunnel is the name for various past, present and planned tunnels in the Stuttgart metropolitan area. Today, there is a railway tunnel under the Rosenstein Park in Stuttgart-Bad Cannstatt. It connects today (2012 ) as part of the Filstalbahn Stuttgart Central Station with the rose stone bridge over the Neckar to the station Stuttgart-Bad Cannstatt.

First Rosenstein Tunnel (1844-1915)

During the construction of the Württemberg Central Railway, the first railway tunnel Württemberg was built directly below the central axis of the castle Rosenstein. This planned by Carl Etzel tunnel linked with Stuttgart Cannstatt. In principle, a circumvention of the Rosenstein would have been possible, but the tunnel has improved the situation of the Cannstatt train station and kept the castle garden from being cut by the railroad. However, its construction was controversial, as critics feared damage to the castle; However, King Wilhelm I declared his agreement. Planning permission was granted on 14 March 1844.

The tunnel was built mining method; Construction began on July 1, 1844 and was completed on July 4, 1846. Completion was delayed by a water and mud intrusion, which had been caused by leaky basins in the lock area. The mud had to be removed from the top, then the basins were sealed. This tunnel was expanded to double track 362 meters long and from the outset.

Once the new tunnel tubes, in November 1915, the old rose stone tunnel was taken out of service in 1916. From 1931 to 1965, he was used by three tenants for mushroom cultivation. During World War II he served as an air raid shelter and was leased until 1946 by Mahle GmbH. The portal towards Bad Cannstatt in 1966 bricked, instead of the portal towards the main station are now underground facilities of EnBW.

At the beginning of the 1990s the tunnel was deconsecrated as a railway system and abandoned. In 1992, the tunnel was transferred to the ownership of the Baden-Württemberg state operation for Property and Construction. He was also as the site of a mineral museum in conversation. Occasionally, it may still be seen.

As part of the Stuttgart 21 project should be carried out in the tunnel for a water pipe to the Neckar excess water in groundwater management.

Second Rosenstein tunnel (since 1915)

When reconstructing the Stuttgart railway facilities at the beginning of the 20th century was, inter alia, the section between the main station and Cannstatt ( and beyond) expanded to four tracks. Since both the planum of Cannstatt station was raised, had to be built a new tunnel. These two double-track tunnel tubes were further east in an open design creates something. Both tubes are 331 meters long.

The two new tubes were built 1912-1914. The first tube went into operation in November 1915. The First World War and lack of money, the work was stopped on the new railway facilities in 1917. On May 26, 1925, the 3rd and 4th track between Bad Cannstatt and the main railway station was put into operation.

All S-Bahn lines S1, S2 and S3 use this tunnel.

Further development

Stuttgart 21

As part of the Stuttgart 21 project, another railway tunnel will be built to replace the current Rosenstein tunnel. A preservation of the existing tunnel has been tested but discarded because in this case the separating effect of the aboveground railway systems in the Lower Castle garden would be retained or should be engaged in mineral -bearing strata during the planning approval.

The 3.4 km long structure is to be built between the new bridge and the existing Neckar S-Bahn tunnel at Central Station. The building joins initially with two double-track tubes on the four-track Neckarbrücke to. In the subsequent crossing road building Ehmann the tube passes under the hitherto remote parallel tracks of the tunnel Bad Cannstatt. After crossing structure, the S -Bahn tunnel branches into two single-track tubes. A branch from the direction of the S -Bahn breakpoint North Station binds to the existing infrastructure of the Stuttgart S-Bahn. In the area of ​​Mittnachtstrasse a branching structure is provided for this purpose in which the tracks will be merged to and from Stuttgart Nord with the tracks to and from Bad Cannstatt before the tunnel at the main station reaches the existing main line tunnel.

The tunnel is part of the zoning section 1.5 of the Stuttgart 21 project, was present for the zoning decision on 29 May 2008.

On 12 October 2010 the shell contract for the tunnel section between the north and the main railway station in the Electronic Official Journal of the European Union was published. The contract to be awarded should be running from April 2011 to December 2019. The construction contract for the arising in the context of the zoning section 1.5 S-Bahn tunnel is to be awarded in 2012. The award procedure, again according to the Deutsche Bahn "advanced" (as of March 2012).

Road Tunnel B 10

Furthermore, a road tunnel with two two-lane, 1,050 m long tubes is planned under the Rosenstein associated with the expansion of the federal highway 10. On 20 May 2010 the Stuttgart City Council approved the 193.5 million -euro construction project. In October 2012, the Stuttgart City Council finally approved the development plan of the project; on November 8, the council majority voted for the construction of the tunnel. Initial work in preparation of tunneling announced the regional press in January 2014, the opening of the tunnel to take place in 2019.

With the construction of the road tunnel of B 10 and the Berger tunnel and the tunnel Schwanenplatz be rebuilt.

Prior to the construction work, the area is scanned along the course of the planned tunnel for possible unexploded ordnance. Aerial photographs of the Allies of World War II suggested this assumption. This assumption was confirmed by finds. Part of the park and the Wilhelma were locked on 28 November 2010 for the public to defuse the unexploded ordnance found.
