A framework for applying slab track on earthworks in Norway [PDF]
, 2019 Fastspor er en sporkonstruksjon der skinner og sviller legges på en betong- eller asfaltplate. Fastspor gir normalt lavere byggehøyde enn spor med ballast, og gir ofte en mer stabil sporgeometri og krever mindre vedlikehold enn spor med ballast ...

Comparison of the technical performance of a discretely supported slab track system and an embedded slab track system in a high-speed railway [PDF]
, 2019 Slab tracks are increasingly used for High-Speed Railways (HSR) as opposed to the conventional ballasted track. This is due to many factors, including increased durability and sustainability, as the slab track can sustain higher dynamic loading with less
