ACCIONA Construction, in anticipation of the next surge of investment in rail infrastructure, and aware of the important role that the ballastless track will play in . Rail traffic is reaching out toward new horizons on ballastless track systems. The arguments are indeed convincing: long life cycles, top speed, ride comfort, and. Stabirail’s new ballastless track or slab track construction system. The most efficient method for laying railway tracks in concrete beds.

The different systems have undergone extensive laboratory and field tests before implementation on grade, bridges and in tunnels.
This experience resulted, for example, in further development of the full-block bi-block sleeper, to design the type B TS-M. Ballastless tracks can be built on either asphalt or concrete supporting layers.
PCM AG -Ballastless Track Systems
We offer an extensive line of concrete sleepers and railway track systems for passenger traffic as well as freight- and heavy-haul transport. Views Read Edit View history. Railway line types Railway track layouts. All systems developed up to now demonstrated that the required accuracy cannot be achieved without any additional construction method, e. Ballastless track assures a permanently stable track position and stands up to the great loads subjected by high-speed train traffic, with performance characterized by top quality, functionality, and safety.

Non-ballasted track, also called ballastless track, is the railway track whose bed is composed of concrete and bituminous mixture, etc.
Advantages High attenuation of vibrations: But for a slab track S.
This type of structure nowadays became interesting due to modern production methods of the slabs and a more simple kind of coupling the six longitudinal bars by sleeves.
Ballasted track is commonly composed of steel rail, railroad tie, railway fasteners and ballast bed. This model was successfully implemented with mono-block sleepers on the Berlin-Hanover high-speed line, in Rathenow. You take no chances with these systems, especially with newly constructed lines: The ICE 3 uses linear eddy current brakes, which heat up the rails. Decisive for thickness design is the bending stress in transverse direction, which can be reduced by prestressing.
The standard fastening system of DB AG for ballastless track ensures this deflection behaviour by a resilient base plate pad with a spring coefficient of This sleeper is characterized by reduction in total structural height. Track systems installed on asphalt supporting layers predominantly feature direct-support configurations: On the other hand, systems implemented with concrete supporting layers offer the selection among an optimal diversity of models with homogeneous system structures.
Rail traffic is reaching out toward new horizons on ballastless track systems. The system is articulated around prefabricated concrete slabs, each of which contains two pairs of prefabricated blocks with premounted elastic fastening. Test track Karlsfeld and Bogl system with coupling of continuous reinforcement. The usual preventive maintenance is limited to rail grinding, since tamping is not necessary due to the absence of ballast.
Comparison of Ballasted Track and Non-Ballasted Track
The rail temperature also has to be taken into consideration as a security criterion in respect of the danger of track buckling. Hence a fine cracking can be activated in a ballwstless of 0.
For high-speed operations, ballastless technology enables more ballasless routing of train lines, with tighter radii and greater slopes.
