Corrugation - Wheel rail corrugation in urban transport
“CORRUGATION” was an EU funded research project which aimed at development of solutions for the expensive and persistent corrugation problem on metro and tram networks. The project started on 1 June 2002 and finished on 30 September 2006. The objective of this website is to disseminate the results of the project towards the general public and the railway industry in particular.
Objectives of the project
The aim of the project was to design and validate efficient and cost effective solutions to reduce or eliminate the corrugation problem. The corrugation phenomena was considered for vehicles with low axle load, running at low speed in curves with small radius, typical urban transport.
Further, the goals were to increase safety, reduce noise and life cycle costs and optimise maintenance costs. These goals have been met.
Several different track and rolling stock solutions have been designed and tested. These solutions include specially developed embedded tram tracks, resilient discrete rail fasteners for metros; corrugation monitoring tools, special friction modifiers…The design of these products was based on a study of all relevant corrugation parameters, on extensive measurement campaigns, numerical modelling, lab tests and on site validation.
The results of the project were immediately exploitable in the urban public transportation networks that were involved in the project and are now also available to other urban networks.
In order to be successful a research consortium was put together. The partnership consisted of several end-users who could directly benefit from the solutions designed in the program, engineering consultancy SME’s, track contractors, a manufacturer of wheel sets, universities and research organisations, a manufacturer of track components and a manufacturer of measurement equipment.
Questions about the products which are developed under this programme can be addressed to firstname.lastname@example.org. We are happy to help you forward.
This project was funded by the European Community under the 5th FP “Competitive and Sustainable Growth Programme”. EC scientific officer in charge was Mr. Joost de Bock.
