Rail inspection of RCF defects
Metalurgija, 2013 Rail defects due to rolling contact fatigue (RCF) threaten the traffic safety around the world. That hazard is more distinct on railways without adequate maintenance strategy. Realization of interoperability of European railway network demands from every

The marginal social cost of road and rail: Implications for rail investment and pricing [PDF]
, 1995 An important issue for transport policy is whether more investment should be devoted to rail schemes and less to road schemes and vice versa. This raises the problem of comparing the returns from investments in the two modes currently assessed on a ...

Reliability of rail transverse flaw detection by means of an embedded ultrasonic based device
MATEC Web of Conferences, 2018 The main causes of train derailment are related to rail defects such as head surface defects, horizontal defects, vertical longitudinal split defects, star cracks at colt holes and diagonal crack in web. The most adverse form of these defects consists of

Enhancing RCF rail defect inspection on the Serbian railway network [PDF]
Građevinski Materijali i KonstrukcijeThe interaction between the wheel and the running rails within the railway system introduces intricate stress patterns, resulting in the formation of rolling contact fatigue (RCF) rail defects. The magnitude of this stress is contingent upon factors such
