A dataset of high-speed video recordings of wheel-rail traction enhancement using a full-scale testing platform

In a process called rail-sanding, the acceleration and deceleration of train can be regulated by applying sand at the wheel-rail interface via an on-board system. A dataset of 78 high-speed video recordings of rail-sanding process using a full-scale testing platform is provided in this data note. The videos are recorded for various case studies, namely different positioning of the sander hose aiming at the rail, nip, and wheel with various angles, and different materials used as rail-sand. The velocities of sand particles is extracted from these high-speed videos using particle image velocimetry software. The spread angle of the particles as they flow out of the sander hose is also measured with the use of image processing software. The data extracted from these high-speed recording can be utilised for calibration, validation, and verification of experimental and numerical set-ups, as well as for training artificial intelligence models.
