TRAVERTEC: Ballastless Track Systems
Sinceit has official German approval for high-speed applications. All of its components can be exchanged individually. On ballastless tracks into the future of railways. Leave a Reply Cancel reply Your email address will not be published. Starting from trackk basis of traditional trough-track designs with mono-block sleepers, RHEDA track models were further developed to track systems with bi-block sleepers.
The success of ballastless-track technology is primarily based on the following advantages: Old definitions from Figure 1 could still be valid today when riding on the first and third generation of ICE along existing old ballasted tracks or on new high speed lines in Germany with ballastless track and trying to write in a notebook. Rail traffic is reaching out toward new horizons on ballastless ballasless systems.
When the less engineering structures bridges and tunnelsthe high speed which requires efforts to increase resiliency of standard ballasted track and significantly reduced maintenance are taken into consideration, the slab track is more superior to ballasted track.
Railroad track is also known as track or railway track.
Comparison of Ballasted Track and Non-Ballasted Track
This model was successfully implemented with mono-block sleepers on the Berlin-Hanover high-speed line, in Rathenow. But for a slab track S. Deutsche Bahn arbeitet an Plan B”. Available measurement results indicate the expected favourable structural behaviour and prove the low maintenance requirements.
The arguments are indeed convincing: Views Read Edit View history. You may also like: This enables the railway to exploit the special advantages of the slab track structure in a much better way.
Chinese Steel Rails Overview How to build a railway track? The development of ballastless slab tracks for full service railways was initiated rtack Europe in the middle of the s by the planning of long tunnels where the track had to be laid directly on a rigid rock or concrete base.
Ballastless tracks therefore offer a high consistency in track geometrythe adjusting of which is not possible after the concreting of the superstructure. Retrieved from ” https: Track-system technology for the railway infrastructure of the twenty-first century.
Railway line types Railway track layouts. In existing old tunnels a minimum structure height can be achieved by an asphalt pavement in ballastleds thickness of only 15cm, to which sleepers are fixed. Ttrack installation performance ballastlesx to the prefabrication and reduced size of its components.
There are some exceptions, for example, in China and France, ballasted track is individually applied in the high speed railway. Hence, for necessary reconstruction of a S. We offer an extensive line of concrete sleepers and railway track systems for passenger traffic as well as freight- and heavy-haul transport. Ballasted track is commonly composed of steel rail, railroad tie, railway fasteners and ballast bed.
The advantages of a ballastless track over a traditional superstructure are its highly consistent track geometry, its longer life span, and the reduced need for maintenance. Generally, laying ballast under the railway sleepers to reduce the stress on the ground. This experience trwck, for example, in further development of the full-block bi-block sleeper, to design the type B TS-M. Elastic mat under the slab.
PCM AG -Ballastless Track Systems
The required rail deflection of 1. This sleeper is characterized by reduction in total structural height. Test track Hoesbach An advantage of systems with anchoring devices for the sleepers Figure 6 is an easy reconstruction of sleepers in the case of derailment or deterioration.
Therefore, the board of DB AG decided in that, for all new high speed lines and upgraded lines to be constructed in Germany, the use of ballastless track has to be considered in the planning phase. Adaptability of vertical rigidity: Experiences in Japan, where this type was laid in a length of km in tunnels Hokuriku Shinkansen line demonstrated, that the costs for the frame-shaped track is eight to 14 per cent lower than that of ordinary slab track 5.
Munich University of Technology. With its comparatively very low structural height, and with the possibility of achieving optimal required track position, ballast track technology offers highly attractive and beneficial solutions as end-to-end systems technology for main-track and turnout sections, for application on a uniform basis on embankments, bridges, and tunnels.
For this type of S. In order to attenuate the vibrations inherent to slab track and enable adjustment of the vertical rigidity, the FASTRACK system has up to three planes of elasticity of scalable rigidity.
The risk of loosening of dowels or anchor bolts of the fastening by free cracking can be minimised by transverse notches on top of the concrete slab with a spacing of balkastless. This wide rail seat spacing should not be used in high speed tracks due to the danger of periodic secondary deflections between the sleepers. This page was last edited on 17 Octoberat Earlier RHEDA models occasionally developed longitudinal cracks between the trough and the infill concrete that could influence the long-term behaviour of the ballastless track system.
A reduction of investment costs deems possible by use of a frame-shaped slab track. When used hallastless stations, ballastless tracks are easier to clean.
Further advantages of ballastless tracks include better and controlled drainagethe elimination of flying-ballast damage on rolling stock and civil engineering structures, a shallower superstructure, and the possibility run-over sections such as crossings over which pneumatic vehicles can be driven.
