Rail corrugation detection by Gabor filtering
Inspection of the rail state in order to detect defects is one of the basic tasks in railway maintenance. Rail defects exhibit different properties and are divided in various categories relating to the type and position of flaws on the rail. In this paper, we propose a technique, based on texture analysis of rail surface, to detect and classify a particular class of defects: corrugation.
متن کاملThrshold Radius for Restraining Rail
This paper deals with the threshold radius that warrants the use of single restraining rail for transit and railroads. Different railways use different threshold radius from 91m to 365m to provide restraining rail. These threshold figures are probably experience driven choices. The need for restraining rail may be related to a so-called derailment alarm coefficient of 1.2 sustained over 2m leng...
متن کاملSoil Mechanics of High Speed Rail Tracks
As high speed rail is becoming increasingly popular around the globe, alignments are being forced onto marginal land due to land costs and the requirement for straight tracks. Rail foundations spread the applied wheel loads to prevent damage to the underlying in-situ soil upon which tracks are built. Designs which cannot sustain the resulting stresses will cause serviceability issues and will r...

متن کاملEffect of Rail Corrugation on the Amount of Train Induced Vibrations near a Historical Building
The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...
