Practical Application of Portable Trolley for the Continuous Measurement of Rail Surface Roughness for Rail Corrugation Maintenance

Rail corrugation not only generates noise and vibrations but also causes track irregularity and deterioration of track material. It is therefore necessary to manage rail corrugation appropriately. Rail surface roughness due to rail corrugation is managed either through visual inspection or with a simple device. As such, this paper describes the development of a portable "Trolley for the Continuous Measurement of Rail Surface Roughness," designed to gather insight into the mechanisms leading to rail corrugation and developing measures to manage it efficiently. This trolley adopts the asymmetrical chord offset method for measuring the rail surface roughness continuously. A software was also built for controlling this trolley and processing the measured data. This paper presents the details of this development and describes some cases where the trolley could be used.
