The Anklam rolling-lift railway bridge was bridging the river Peene at Anklam in the German federal state of Mecklenburg-West Pomerania. It is situated on the double-track electrified Berlin- Stralsund line. The bridge was designed and built using the principles developed by the American engineer William Scherzer (1858-1893) and is one of the oldest remaining bridges of this type in Germany. It consists of three main parts per track. On a townside-located southern support roller tracks are mounted on which a pair of toothed wheels whith overhead mounted counterweights can roll off to open the second part - the rolling lift. The third part - a fix foreshore bridge - is located between the riverside pier and the northern support. Since march 2011 - because of defects on the bearing construction - the lower support is being fitted by DB ProjektBau GmbH and the superstructures are being replaced by hydraulic-moved lifts and new fix foreshore bridges. The rolling lift bridge of William Scherzer will be preserved as a technical memorial and erected next to the new bridge. The two tracks are expected to be back in full service by June 2013.

After a construction period of some nine years the 9 385 meter- long Katzenbergtunnel was opened in December 2012. The largest single civil engineering structure on the new and upgraded line Karlsruhe-Basel is the third-longest tunnel in the DB Netz AG network. In addition to the outstanding engineering accomplishments, the tunnel is remarkable on account of its many innovative technologies and concepts. Among the innovations are the safety concept with two single-track tun-nels which are connected with one another by 19 connecting galleries at intervals of 500 meters, the solid carriageway which may be used by road vehicles, the new method used to affix the overhead lines, and the sonic boom constructions which prevent a tunnel boom effect. All these solutions make the Katzenbergtunnel one of the most modern constructions in European rail transport as it sets the highest standards and serves as a prototype for future tunnel constructions in Deutsche Bahn's high-speed network.
Tunnel rastatt: Largest construction project in section 1 of the planned third and fourth railway track between Karlsruhe and Basel [Tunnel rastatt: GroBtes bauwerk im strecken- abschnitt 1 der ausbau- und neubaustrecke karlsruhe-basel]

With a total length of 4270 metres. Tunnel Rastatt is one of the main projects for the planned third and fourth railway track between Karlsruhe and Basel. The financing agreement with a total volume of EUR 700 million was signed in 2012; the first construction works are to begin at the end of 2013. At the end of 2015 two machines are likely to start boring parallel single track tunnel tubes underneath the city of Rastatt. Preparing the tunnel carcass will take approximately four to five years; the completion of the tunnel is planned for the year 2022. In the same year, the section of track - with a total length of 17 kilometres - is to be put into service.

So far no experiences could be accomplished with bridges in the field of high-speed trains due to high stresses with possible appearances of resonance. This issue has to be treated very sensitive from the design stage on. Little tricks will help to improve the dynamic performance. This contribution deals with the modeling of the impacts and the structure of the high speed train bridges as well as the evaluation of results of calculations. Problems of ultimate limit strength and fatigue strength are being discussed for some examples because dynamic factors as well as working load factors are no longer correct if resonance is occuring. © Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

The northernmost section 1 (StA 1) of the section of line being upgraded (ABS) and newly built (NBS) between Karlsruhe and Basel runs from Karlsruhe to Rastatt Süd. 16 km of new line is being built, which should be in operation in 2022. The core structure of StA 1 is the 4, 270 m long Rastatt Tunnel, the second largest engineered structure in the overall ABS/NBS Karlsruhe-Basel project after the Katzenberg Tunnel. The main contract for the construction of the tunnel was awarded in August 2014. The first preparatory construction measures on site started in summer 2013. Due to the prevailing conditions of topography and existing infrastructure and the continuously increasing requirements of approvals and codes, the construction of the Rastatt Tunnel poses great challenges for the engineers, which demand innovative solutions in design and construction as well as a collaborative approach from all those involved in the project. © 2015 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

In order to relieve the existing S-Bahn urban transit railway trunk line under the inner city of Munich, the construction of a second S-Bahn trunk line with a further inner-city tunnel is planned, which will also link the transport nodes at the Hauptbahnhof main station, at the Marienhof/Marienplatz and at the Ostbahnhof east station. The two-track line is about 10 km long, of which about 7 km will run in tunnels, and will mainly run in the Tertiary at a depth of about 40 m due to the existing dense building and underground transport routes that have to be crossed. The platform level of the three new stations will also be correspondingly 35 to 41 m deep. The high water pressures and the cross-sections of the station tunnels of up to 330 m2 pose particular challenges for the design and construction of the stations. The article provides an overview of the overall project and the special technical features of the tunnels.
Bridge over scherkonde valley - the first large semi-integral bridge on high-speed railway route erfurt - leipzig/halle [Die scherkondetalbrücke, die erste semi-integrale talbrücke der DB AG auf der neubaustrecke erfurt - leipzig/halle VDE 8.2]

Currently some large valley bridges are under construction on high-speed railway route Erfurt-Leipzig/Halle. These bridges follow a new holistic design philosophy. The superstructure of those integral or semi-integral bridges is rigidly connected to the abutments and the columns. Therefore they are more slender than conventional bridges, and the bridges are very robust and durable because of the omitting of bearings and dilatation joints. The bridge over the Scherkonde valley is taken as an example for explaining the differences between conventional and semi-integral bridges in this paper. This example shows the advantages and the requirements of integral buildings for high-speed railway bridges.Copyright © 2010 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

The first German railway went from Nuremburg to Fürth in 1835. One hundred years later electric railway operation was started on the Treuchtlingen-Nuremberg line. Electrification was completed for the time being by the inauguration of the Nuremberg-Ingolstadt line. Current and future projects are geared to fully electrify the railway network and extend it to communicate with Saxony and the Czech Republic.

The subject of this article based on the Kaiser Wilhelm Tunnel is the derivation of a list of criteria for overcoming critical situations during tunnelling at the borderline of open mode to closed mode operation. The consistent application of this list of criteria demonstrates, that with knowledge of the sensitive interaction of machine and surrounding ground, the scope of application of current machine technologies can even be extended into geologically difficult areas. Formerly, this led to considerable problems, at times even economic failure of the project   . The advantages the use of the catalogue of criteria has, si shown in the example of a shield machine with earth pressure components © 2011 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

The Stuttgart-Ulm railway project is a central investment in the future for the German state of Baden-Württemberg. The new line will be part of the European high-speed rail network "Magistrale for Europe", linking the European metropolitan areas of Paris, Strasbourg, Munich and Vienna along a central west-east axis to Bratislava and Budapest. Altogether, the Stuttgart-Ulm railway project includes the rearrangement of the Stuttgart rail node and the new line Wendlingen-Ulm. The joint venture ATCOST21 under lead company Porr has been awarded the contract for the Filder Tunnel and the approaches to Ober- and Untertürkheim. Employer and contractor intend to develop the project as partners with the aim of technical and commercial optimisation under the terms of the contractually agreed partnering model. © 2012 Ernst & Sohn Verlag f?r Architektur und technische Wissenschaften GmbH & Co.
