Using ACSW on the Railway

Reliability and the ACSW solution
Reliable ground stiffness data is vital for the safe and economical design of both trackbed and structures on the railway. Obtaining ground stiffness data often involves large plant or disruptive activities which can pose a considerable risk in a rail environment. The equipment required is often unsuitable for access to remote or restricted locations and unsuitable for use during limited duration possessions. As a result often only limited investigations are undertaken and ground stiffness is unreliably and therefore conservatively estimated via empirical relationships with other tests.
