In a rail track structure, turnout is used as transition between straight and branching rails therefore withstands complex dynamic rolling impact loading. This paper reports comprehensive failure investigation of railway off-track made from Hadfield austenitic cast steel. The worn was examined using optical microscopy, scanning electron micro-hardness, quantitative X-ray diffraction analyses. A...

Existing bridges are aging and deteriorating rapidly, elevating concerns for public safety preservation of these valuable assets. Large numbers exist in transportation networks, the current budget limitations worsen situation. This necessitates development an automated condition assessment rating methods. Spalling is a common problem that majorly influences health, safety, structural integrity ...
