BALLASTLESS TRACK SYSTEM PDF

Up to now most of the ballastless track systems, which have been built on Ballastless track systems using discrete rail seats as well as systems with sleeper . The Group (formerly ‘Pfleiderer track systems’) was involved from the earliest days in a leading role for the development of ballastless track systems. At the beginning of the s, the ÖBB started using ballastless track systems. During the first phase (from until ), several different types of ballastless .

Related regions AustriaTurkey. The mats are then covered with plastic sheeting to prevent intruding concrete and thus forming acoustic bridges.

At the beginning of the approval process, it is initially necessary to clarify which parties will be called in for ballastles approval procedures and which requirements must be satisfied. We use cookies to improve your experience on our site and to show you relevant advertising. This sleeper is characterized by reduction in total structural height.

sytsem The restoration of the Berlin MRT system the S-Bahn enabled gaining of extensive valuable insights into the structural engineering of such track systems. The elastic mats also allow the use of stiff and therefore simpler fastening systems from all leading manufacturers. The elastic RockDelta mats truly demonstrate an outstanding degree of effectiveness and long service life — even after decades of operation on conventional mainline routes.

During these years he received a Doctors degree in Technical Sciences. Achievement of approval for a current project requires zystem evidence to show conformity with the additional or differently formulated requirements posed by the present project.

TRAVERTEC: Ballastless Track Systems

Within the context of the project, furthermore, IRCON also took part in the planning and construction of numerous bridges. Your email address will not be published. Slab Track “Swiss Made”: These criteria have been shown to lead to extensive discussions in all foreign track projects and for the approval of ballastless track systems abroad.

Especially for use in tunnels, which is the main area of application, seems to be effective as well as in Austria. By using this site, you agree to the Terms of Use and Privacy Policy. In addition, neither the bi-block concrete sleepers nor the highly sywtem System rail-fastening system by Vossloh accorded with specifications for state-of-the-art in India and likewise required discussion within the framework of the overall process.

Accept Reject Read More. Approval of the concrete track-supporting layer proved to be considerably more difficult. Starting from the basis of traditional trough-track designs with mono-block sleepers, RHEDA track models were further developed to track systems with bi-block sleepers.

Further disadvantages of ballastless tracks are the impossibility of adjusting or correcting track geometry once concrete has been rtack, the necessity of a stable infrastructure since no adjustments can be made to the superstructurehigher noise emissions, and longer repair times when the concrete slab is damaged e.

systsm ONE succeeded tracm convincing the customer to have the dimensioning and construction of the tunnel investigated by highly qualified European experts — an examination that has not yet been concluded. One purpose of the ballastless track is to reduce to an absolute minimum any access by unauthorised maintenance staff who are considered security risks.

Only in such a way was it possible in this project to preserve ballastlexs basic principle of the ballastless track system, with its load-distributing slab and its crack-limiting reinforcement.

The arguments are indeed convincing: This site uses Akismet to reduce spam. All of its components can be exchanged individually. Now Patil Group is making its contribution in Metro Rail projects.

For noise and vibration reduction, many of these systems are combined with floating slabs. Therefore, ballastless track forms will be needed as well. Subsequently definition likewise takes place for the optimal combination sytem slab thickness and type of elastic mat.

The RHEDA RX ballastless track system masters with ease the great loads arising from metro transport and minimizes undesirable vibrations. ONE performs all planning tasks, up to and including official approval of the system and its components by the local Indian authorities.

The engineering design of this model guarantees a high degree of exactness in track gauge, as well as in overall track geometry.

The ÖBB/Porr ballastless track system

In many cases, a maintenance-free track system is indeed the more cost-effective solution over the long run. Track systems installed on asphalt supporting layers predominantly feature direct-support configurations: If you continue browsing, we consider that you accept their use.

The mats were designed with special consideration taken of these required ballastlses.

Therefore, ballastless tracks must be concreted within a tolerance of 0. 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 ballstless run-over sections such as crossings over which pneumatic vehicles can be driven.

Ultimately, ballastlss project dealt with two offices; one for the track components, and another for bridge construction for approval of the concrete components e. Photocatalytic Product Over the syste decades, there has been growing concern regarding environmental pollution in large cities. With the RHEDA ballastless track system, we make our significant contribution to implement high-performance rail infrastructure in India.

The main activity, however, is related to the Indian Railways. Especially for pilot projects, it is tgack advisable to elaborate for the investigating engineers, the special criteria of a ballastless track system — i. The most ambitious railway project currently underway in India is the connection of the Kashmir region to the area at the foot of the Himalayas and the rail lines ending there that lead to Delhi and other metropolitan areas.

For switches and crossing areas, special ballastless systems consisting of booted monobloc sleepers were developed and are still in use now. Due to various BLT systems are available.
