Doha Metro Track Works
Underground
Metro Doha is the first underground railway in Qatar and was newly integrated into a rapidly developing modern metropolis.
All in all Metro Doha comprises a length of 172 km in phase 1. This approximately corresponds to the total underground railway network in Vienna. Within the scope of phase 1 of the Metro Doha project four underground lines are constructed.
The track system was designed as ballastless track system STA (Slab Track Austria) including sections of mass-spring systems. The planning comprised tunnels, at-grade and bridge sections. In addition to the main tracks, turnout areas and the associated transition areas were established. As a basis for slab track design the existing alignment was revised and optimized.

Main Focus
„ I was personally impressed that the construction workers have accomplished the installation of the slab track within a very short time despite the difficult working conditions with temperatures of more than 40 degrees in the shade. “

Analyses for determining the requirement of emission reduction measures (e.g. mass-spring systems) were performed for providing the protection targets for neighbours regarding vibrations, ground-borne noise and airborne noise. Comprehensive measurements and analyses were performed on site as a basis for these calculations.
