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 .

Only in such a way was it possible in this project to preserve the basic principle of the ballastless track system, with its load-distributing slab and its crack-limiting reinforcement. This sleeper is ballastlexs by reduction in total structural height. This solution effectively isolates vibrations resulting from passing trains.

Imprint Data protection Disclaimer. Highly developed installation technology, sophisticated just-in-time logistics in deliveries to the construction eystem, and highly efficient project management: Systtem high-speed operations, ballastless technology enables more direct routing of train lines, with tighter radii and greater slopes.

The elastic coating consists of a PUR-bound granular rubber. The reasons for that are the much reduced maintenance necessities, the safe run of the trains and the good behaviour of the system in case of derailment events. Stability, precision, and ride comfort Long life cycles and practically no maintenance Flexibility and end-to-end effectiveness in application Basis for optimal routing of rail line.

The ÖBB/Porr ballastless track system – Global Railway Review

Additional documentation in verification of requirements was requested only for the sleeper shoulders of the System rail-fastening system, which were slightly higher than bllastless the W14 track. Schilder was in charge of Track Technologies. This partnership with the Indian Railways is continuing for more than three decades.

ONE is furthermore in a position to realise the planning of a railway track system, up to and including official approval, within stipulated time-schedules and budgetary constraints. Elastic mat under the slab. Rapid transit can mean rough conditions. Mortar is used to connect the 9-ton-slabs to the infrastructure and to one another. This dual organisation complicated the approval process significantly, since these two departments operate in accordance with different specifications and dimensioning criteria.

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.

One additional and special challenge results from the politically tense situation within the Kashmir region. By application of the balpastless described above, it is possible to handle such discussions in a ballastlees controlled manner. Approval of the concrete track-supporting layer proved to be considerably more difficult. Website development by e-Motive Media Limited. 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.

This experience resulted, for example, in further development of the full-block bi-block sleeper, to design the type B TS-M. In many cases, a maintenance-free track trqck is indeed the more cost-effective solution over the long run. This model was successfully implemented with mono-block sleepers on the Berlin-Hanover high-speed line, in Rathenow.

This means, above all, that details such as transitions, connections and other interfaces must be shown clearly and at the required scale. You take no chances with these systems, especially with newly constructed lines: The company Patil Pfleiderer track systems Pvt.

At the moment, and in the near future, a couple of new high-speed railway lines will be built in Turkey. Rail traffic is reaching out toward new horizons on ballastless track systems.

Therefore, this ballastless track system has been abllastless at new, large railway connection projects in Berlin: This site uses Akismet to reduce spam. The mats are then covered with plastic sheeting to prevent intruding concrete and thus forming acoustic bridges. It is possible only in this way for planning engineers as well as approval engineers to achieve a level of knowledge that can serve as sufficient basis for collaboration in the sense of mutual trust.

Rail traffic is reaching out toward new horizons on ballastless track systems. These two elastic elements have to be copied by vallastless elasticity of the rail fastening system in the ballastless track and of the elasticity of a second layer which is situated at the bottom of the prefabricated slabs.

Sinceit has official German approval for high-speed applications. This page was last edited on 17 Octoberat Leave a Reply Cancel reply Bqllastless email address will not be published.

The ÖBB/Porr ballastless track system

At the moment, the maximum line speed is kilometres per hour. Railway line types Trrack track layouts. The Patil Group of Industries and Pfleiderer Track Systems-two partners with decades of experience in railway infrastructure-have combined their resources to support the Indian Government in the implementation of their plans.

It was first tested inbecame the standard system in Austria in[10] and has been used for over kilometres of track worldwide, including the German Verkehrsprojekt Deutsche Einheit Nr.

Is there any details available? For switches and crossing areas, special ballastless systems consisting of booted monobloc sleepers were developed and are still in use now. Later in this article, salient differences here will be covered in greater detail.

Numerous expert presentations made by RAIL. As a result of its collaboration with many European and Asian approval authorities, public offices, and railway organisations, RAIL. This especially represents obstacles for nallastless approval of such track systems, since authorities often expect that ballastless track systems should fulfil alternative stipulations from the field of conventional track construction and concrete engineering.

The restoration of the Berlin MRT system the S-Bahn enabled gaining of extensive valuable insights into the structural engineering of such track systems.

ONE engineers and concrete technologists, however, succeeded in confirming that the two criteria are not entirely contradictory, after more detailed consideration of syshem definitions involved. Related people Jens Kleeberg.
