Rail roughness measurements for Crossrail: Phase 1 - Modifications to the measurement device (RR-DYN-95-061)

Crossrail have adopted a prediction model for re-radiated noise from trains in tunnels which is wholly dependent on input data for the roughness of the wheel and rail. Accurate and representative roughness measurements are required to ensure valid predictions. Contract D5504 provides for British Rail Research to modify an...
