This paper presents an experimental study on the development mechanism of short pitch corrugation using an innovative downscale V-Track test rig. Rail corrugation is reproduced in the V-Track with two wavelengths of 6.4 mm and 8.9 mm. Based on the measured wheel-rail contact forces, track dynamic behaviors, and observations, the consistent...

This paper investigates three-dimensional (3D) rail vibrations under fastening constraint up to 5000 Hz and provides insights into rail vibration control by fastening parameters. A methodology is proposed, including experimental investigation and numerical simulations of rail vibrations. Three steps are considered: 1) experimental investigation...
