The Initial Situation:
In one of the largest cities in southern Germany, a major railway project is to be implemented by 2026. Four new stations, 56 kilometers of tunnel tubes, 11 tunnels, 42 bridges and around 100 kilometers of new tracks, which will be used at speeds of up to 250 km/h, will be built. Part of the rail project is the high-speed line Wendlingen–Ulm. The line crosses the low mountain range of the Swabian Alb at speeds of up to 250 km/h and is part of the “Priority Axis No. 17” of the Trans-European Networks (Paris-Budapest/ Bratislava, the so-called “Magistrale for Europe”) and its Rhine-Danube corridor.
The Project:
The project includes the construction of the high-speed line for long-distance, regional and freight traffic across the Swabian Alb, which will run parallel to the A8 motorway in many sections. The 60- kilometre-long new line runs through seven two-tube tunnels. The reasons for the construction of this high-speed line are to significantly reduce commuting time for travelers and to improve local infrastructure. RAILONE’s proven RHEDA 2000® ballastless track system was selected for this project because it is very cost-effective and has a long service life with low maintenance. In addition, the RHEDA 2000® system is very flexible, so installation work can be carried out while operations continue. Construction work for this project began in 2010 and was completed in 2022.
Project Details:
- Line length: 60 km
- Line operating speed: 250 km/h
- RAILONE scope of delivery:
- 184,000 B 355 sleepers
- 40 turnout sets
- 6 rail extensions
More About RHEDA 2000®:
The RHEDA 2000® system is RAILONE’s contribution to reliable high speed rail technology: this track is ideal for heavy loads, for extreme speeds, and with top safety. The monolithic, ballastless RHEDA 2000® system represents the most advanced stage of development in the RHEDA family. This system is used for mainline tracks, especially on high-speed routes. Chief characteristics of the supporting concrete slab include its lack of a trough, and its use of a modified bi-block sleeper with a lattice girder.
The development of special turnout sleepers for the RHEDA 2000® system means that track and turnout are totally compatible: the uniform structural height and the reduced weight enable significant time and cost benefits in project engineering and installation. As a result of the monolithic structure of the track-supporting layer, and the low overall structural height, this system is outstandingly suited for applications for earthwork systems, tunnels, and bridges.
Your Advantages:
- A maximum of cost effectiveness and reliability by utilisation of concrete sleepers as superior- quality precast concrete building components in the critical area of the rail-seat zone.
- Great precision of track-geometry parameters by application of precise concrete sleepers.
- Great adaptability to all types of substructure and models executed, by means of application of cast-in-place concrete for the concrete track-supporting layer.
- Great reliability as a result of technologically mature concrete engineering of the track- supporting layer for a great diversity of climatic conditions and concrete standards.
- Flexible, high-performance installation procedures on the basis of simple installation steps that are reproducible for both manual as well as automated procedures.
- Great added value by local production possibilities.
