Loads for Slab Track
Slab track systems although widely developed so far as technological specific proprietary systems, are now more widely developed in collaborative projects (e.g.Capacity4rail), as well as specific standardization work is carried out. This would help generalizing their implementation taking into account slab track systems main strong points, namely low maintenance effort as compared with ballasted track.
Load models are important for slab track design, as their correct specification may involve significant differences in the slab system design, dimensions, and internal characteristics. At the end of the day, significant savings in the overall system costs may be expected from tailored load models.
After a review of current international practices in slab track design, the main current trends as they appear in published material as well as in standards , currently at the enquiry step, will be presented and shortly discussed.
