Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.Crack detection at the pixel level across complex scenarios (structural interference and adverse working conditions) is a critical consideration in the maintenance of ballastless track slab (BTS). Although existing deep learning models achieve acceptable accuracy on cracks with a monotonous background, the ground truth with high labor cost is ...

Circular Slab Track—Structural Analysis of Adapting Composite Materials to Ballastless Track Systems
InfrastructuresRail transport is widely regarded as an efficient and environmentally sustainable mode of mobility, although lifecycle emissions from infrastructure can diminish its ecological benefits. This study assesses a novel slab track system design that replaces conventional concrete components with recycled polymeric composite sleepers, supporting circular ...

Interaction Between Superstructure and Substructure in Railways [PDF]
, 2010 The railway track superstructure undertakes the forces that develop during train movement and distributes them towards its seating. The track panel (sleepers with their fastenings or slab with the fastenings) plays a key role in terms of load ...
