Description

The Hogesnelheidslijn-Zuid – HSL-Zuid, witch stands for High Speed Line – South, is the first high speed railway route for 300 km/h in the Netherlands. It runs from Amsterdam via Rotterdam to the Belgian border. It connects the major Dutch cities into the Transeuropean High Speed Rail Network (TEN).

The Hogesnelheidslijn-Zuid (High Speed Line – South) runs southwards from Amsterdam Schiphol parallel to the A4 motorway, to Rotterdam and from there parallel to the A16 with a connection to Breda and further on to the Belgian border. The construction type used is Rheda 2000®. The 260000 sleepers are positioned in a two-stage process: In the first step the sleepers are lifted from ground and positioned reaching an accuracy of 5 mm. For this step three appropriate machine were constructed. Their machine guidance system was developed by intermetric. During construction the 3 machines were guided by intermetric engineers. The second step is to reach the final precision for each and every of the 260000 sleepers: internal accuracy of 0,5 mm regarding lateral and vertical position as well as inclination. This was reached by applying another development of intermetric, the “intermetric Laser Alignment with Active Target” process. Again intermetric engineers guided the process on site. Once in their exact positions, the sleepers are cast in place with concrete. The final work is to provide the exact position of each sleeper and their relative deviation from design in oder to identify wrongly positioned sleepers. intermetric engineers measured the final track position and provided the needed lists.

The Netherlands are building their first high speed railway route, for 300 km/h, from Amsterdam via Rotterdam to the Belgian border, and the major Dutch cities will be connected in to the Transeuropean High Speed Rail Network (TEN).
