As we are anticipating the next boom in investment in railway transportation, conscious of the important role that slab track is to play in that, and aware of the drag on competitiveness caused by the use of commercial systems, ACCIONA has promoted the development of its own slab track system. The system is articulated around prefabricated concrete slabs, each of which contains two pairs of prefabricated blocks with premounted elastic fastening. 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. Elastic mat under the slab. Horizontal efforts are transmitted to the ground by a steel stopper or fastening system, made of two concentric cylinders that slide along each other, allowing the free vertical movement of the slab. Over the last decades, there has been growing concern regarding environmental pollution in large cities.

Superior stability, the absence of deformation and a shallower construction height are just some of the advantages slab track , also known as ballastless track , offers compared to its traditional counterparts.

The laying of ballastless railway track used to be a time consuming job. Stabirail has designed and developed a groundbreaking method for milling concrete blocks.
Our ballastless track construction system is a continuous process in which rails can be assembled directly on the concrete bed with millimeter accuracy, thus guaranteeing faster construction times at a lower cost.

The demands on the track system have changed greatly since the start of railways. This applies not only to parameters such as axle load and speed, but also less obvious factors such as train length and frequency. In addition to the classical design of track grid floating in ballast, other non-conventional designs have been developed with varying degrees of success. The railway permanent way has an average useful life of between 30 and 60 years.
Posted: 23 August No comments yet. The different systems have undergone extensive laboratory and field tests before implementation on grade, bridges and in tunnels. Available measurement results indicate the expected favourable structural behaviour and prove the low maintenance requirements. With increasing speed and a lay-out of lines with extreme track parameters — e. For evaluation purposes, it is necessary to take into consideration the interaction between vehicle and track. Passengers have always assessed riding comfort in a train by their individual impressions. 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.
