In the scope of Phase 1 of the Doha Metro project four underground railway lines shall be constructed on a total length of 172 km. The track system is designed as ballastless track with Porr slab track system and some sections as mass-spring systems. The design comprises tunnel sections, at grade sections, tracks on viaducts as well as turnout areas and the associated transition areas. As basis of the layout of the ballastless track the available alignment is revised and adjusted by VCE.
VCE carries out analyses on the requirement of emission reduction measures (e.g. mass-spring systems) for providing the protection targets regarding vibrations, ground-borne noise and airborne noise. Extensive measurements were performed on site as a basis for these calculations.
