– 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.
