The Vienna underground transportation company 'Wiener Linien' installed a working group of experts for noise and vibrations, railway engineering and maintenance to develop a new ballast-less track system. This system shall be based on the fundamental principles of the existing 'Wiener Oberbau' but shall avoid its disadvantages. After a first study of four different ballast-less track solutions and a selection procedure in the working group, the further work focused on two remaining types - a solution with prestressed mono-block sleepers and a solution with twin-block sleepers - in both cases the sleepers have an elastic coating and are embedded in a continuous floating concrete track slab. This slab is situated on an elastic layer and therefore the whole system can be called mass-spring-system. For these two types of superstructure a 300 m long test track was realised. The extensive testing and evaluation programme contents an evaluation of the construction process; tests with different speeds with unloaded and loaded vehicles with measurements of deformations, vibrations and noise and a comparison of the life-cycle costs. The targets of the working group were reached by the new twin-block system.
