DEVELOPMENT OF NEW RAILWAY TRACK STRUCTURES

In contrast to the existing standard track structure with ballast and cross-sleepers, partially or wholly modified structures will here be called the new track structures. Ballasted track deflects and subsides under repeated passage of trains over it and loses the levelness of the running path. The volume of maintenance work increases in proportion to the speed-up and the frequency of train operation. The aim of first applying it to tunnel section and elevated track and ultimately extending the application to the common track sections, the concrete slab type track has been developed.
