Developments in railway tracks
28 December 2008 | By Prof. Coenraad Esveld, Director of Esveld Consulting Services and Em. Professor of Railway Engineering, TU Delft
One of the most important developments in the last decade was the large scale application of slab track. This is in particular the case for high-speed tracks. In countries like The Netherlands, with very soft soil conditions, classical high-speed tracks could only be realised without massive soil improvements via grouting…

Weld registration and acceptance
27 September 2008 | By Coenraad Esveld, Director of Esveld Consulting Services (ECS), Professor of Railway Engineering, TU Delft and Global Railway Review Editorial Board Member
For a long time now, poor weld geometry has been a major problem for railway infrastructure. Due to geometrical imperfections, high dynamic loads could be generated during wheel passage. The only way to control the geometrical quality in an effective way, is by measuring and documenting every weld with an…
