D2S International NV
D2S is a Belgian high-tech company dedicated to research and development related to the rail industry in the area of noise and vibrations. D2S undertakes noise and vibration studies for end-users (railway operators, infra managers and urban rail transport companies). The company also carries out advanced research and feasibility studies on behalf of industrial customers in the rail industry in order to optimise the products and/or to troubleshoot existing problems. D2S works on track infrastructure as well as on rolling stock. D2S has all the equipment to perform the measurement of noise, rail & wheel roughness, vibrations, track decay rate, …
D2S has highly skilled technical staff with engineers holding doctor degrees in various disciplines including mechanical and civil engineering. The D2S engineers have more than 30 years of experience in rail inspection and structural evaluation technology. D2S is currently actively involved in several collaborative research projects funded by the industry, the Belgian government and the EC.
Staff of D2S has been involved in following relevant EC research projects:
– 5th FP: SQUEAL.
– 6th FP: WIDEM, MODTRAIN, SILENCE, URBAN TRACK, SPURT.
– 7th FP: PMNIDEA, ACOUTRAIN, CITYHUSH.
Role within the consortium
D2S will be responsible for monitoring the rail roughness growth following the grinding interventions at Infrabel and DL. It will carry out the necessary noise and rail roughness measurements and will contribute to the development of the rail roughness growth rate model.
Reason for participation in the project
As noise consultant, D2S is interested in the relationship between rail roughness and noise to better advice its customers in this area of rail maintenance.
