The Mainz bypass is a bypass of the Mainz main station railway junction mainly used for freight traffic . It connects the Main-Rhein-Bahn , the Mainbahn , the Taunus-Eisenbahn and the Linke Rheinlinie and was opened in 1904.

prehistory

Even after the Mainz main station was moved to its current location in 1884, it soon became a bottleneck for traffic again. This was mainly due to the Mainz tunnel, which had only two tracks .

Construction and routing

The Prussian-Hessian Railway Community and the governments of the Kingdom of Prussia and the Grand Duchy of Hesse-Darmstadt behind it decided to solve the problem with a bypass railway in 1900. For this, however, a complex route was necessary because of the bridges required. But she avoided the freight train traffic through Mainz main station. Construction work began in 1902 and was divided into four lots. On May 2, 1904, the line went into operation and was subordinated to the Mainz Railway Directorate.

Kaiserbrücke (1904)

The kilometering of the 15.1-kilometer route begins at Mainz-Mombach train station . Then it crosses the Rhine on the (then) newly built Kaiserbrücke , there (today) reaches Wiesbaden city ​​area and crosses the Taunus Railway south of the Wiesbaden Ost train station . There are crossing-free entrances and exits in the direction of Wiesbaden and Koblenz.

The railway goes around Mainz-Kastel in a wide arc . In Mainz-Kostheim she meets the Taunus Railway again. At the Kostheim junction you can change to and from the route in the direction of Frankfurt. The branch in Kostheim was originally called "Abzweigstelle K". It received its current name in 1905.

Then it reaches the Kostheimer Bridge over the Main , crosses the Rhein-Main-Bahn and drives in a wide arc into the Mainz-Bischofsheim train station . From there, you can continue your journey via the Mainbahn to Frankfurt (Main) Hauptbahnhof (and formerly to the now demolished main freight station ) and via the Rhein-Main-Bahn to Darmstadt Hauptbahnhof .

The construction of the bypass railway also enables trains coming from the left bank of the Rhine from the direction of Worms to be guided without changing direction in Mainz main station in the direction of Frankfurt and to Mainz-Bischofsheim station . However, this variant again requires the use of the Mainz tunnel and is therefore only used relatively rarely.

→ Main article : Igelstein connecting curve

Since the beginning of 2011 is planning permission for the construction of a single-track connecting curve from the former junction Mainz-Kastel hedgehog stone to the East Rhine Railway as part of the emergency program seaport hinterland transport . According to the tender, a single-track, 1200 meter long connection is to be built, including two framework structures. Thanks to the curve, all freight trains could be routed via the bypass line instead of through the city of Mainz-Kastel , which would reduce the potential for conflict with regional traffic. So far, the project has not gotten beyond preparatory work; whether and when it will actually be implemented is currently not foreseeable.

Architectural monuments

This alignment of the Mainz bypass required a number of bridges. The historic bridges are all designed as overpasses of the bypass railway over intersecting infrastructures and the two rivers. Due to the construction period, its design is and was largely shaped by historicism with numerous details in Art Nouveau , e.g. B. at the bridge railings. Part of this original design has been preserved, others, especially at the Kaiserbrücke, were destroyed or damaged in the Second World War and rebuilt in greatly simplified forms after the war. The following are rated as cultural monuments according to the Hessian Monument Protection Act :

• Kaiserbrücke over the Rhine
• Hochheim railway bridge over the Main

traffic

When it opened, the line served exclusively as a freight bypass . The southern section between the Kostheim junction and the Mainz-Bischofsheim train station has also been used by local public transport for many years . In particular, the S9 S-Bahn line of the Rhein-Main S-Bahn runs here . The northern section, north of the Kostheim junction , was used almost exclusively by freight trains until December 2018. Exceptions were made for construction work in Mainz or at the Mainz Südbrücke as well as for operational disruptions; According to the schedule, only a few passenger trains were run over this section of the route, for example in the 1999 summer timetable an ICE booster on the way from Frankfurt to Koblenz, the EuroNight Jan Kiepura when it was still traveling between Frankfurt, Warsaw and Moscow , and the trains of the here in August 2016 the last Hamburg-Cologne Express service . Since the timetable change on December 9, 2018, regional express trains on the RE 4 and RE 14 lines between Mainz Hauptbahnhof and Frankfurt Hauptbahnhof have been run every hour over the northern section to the Taunus Railway, so that now only the connecting curve between Mainz Nord and the northbound one left Rhine route except for the once daily RB33 (Wiesbaden Hbf - Ingelheim - Bad Kreuznach) without passenger trains.
