MMW‐FC: A novel railway fastener detecting method based on millimetre wave radar for train positioning

IET Radar, Sonar &Navigation, Volume 18, Issue 7, Page 1094-1105, July 2024.
A novel method is proposed for rail fastener detection based on millimetre‐wave radar, which can accurately detect and enumerate the fasteners in real‐time as the train traverses its route. Under circumstances where GNSS signals remain unavailable for prolonged durations, precise train localisation can be accomplished by correlating the number of ...

Intelligent recognition of defects in high‐speed railway slab track with limited dataset

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 6, Page 911-928, 15 March 2024.
Abstract During the regular service life of high‐speed railway (HSR), there might be serious defects in the concrete slabs of the infrastructure systems, which may further significantly affect public transportation safety. To address these serious issues and fulfill the regular functions of HSR, the traditional methods for railway engineers involve ...
