AT A GLANCE
For the renewal of the Sägenöschstraße level crossing, SBB was looking for a replacement for rail, sleeper, ballast and for the level crossing panels. Sustainability, as well as ecological, social and economic aspects played a decisive role for the SBB.
After a detailed examination of the STRAILway polymer sleepers and the pedeSTRAIL level crossing system, the decision was made in favour of the products of the Upper Bavarian company, as they fully met all requirements.
In addition, the STRAILway polymer sleeper has a W fastening milled into the sleeper. This means that no ribbed plate is no longer required. The number of fastening components is also significantly reduced and the installation of the sleeper is simpler and more efficient. This also results in a cost saving.
The construction work for the renewal went smoothly. First, the track yoke was assembled in a preliminary layer, as the STRAILway polymer sleepers differ in height and weight from wooden sleepers as follows:
height and weight wooden sleepers: 15 cm, 86 – 96 kg,
height and weight of STRAILway polymer sleepers: 16 cm, 129 kg;
The track yoke was then rebuilt using a conventional working method. A two-way excavator and aTM 234-4 were used.
