A cost/benefit study of in-track weld straightening considering various strategies for using the RASTIC & SUPERLEV systems (TM-TM-031)

4. CONCLUSIONS 4.1 All of the options for using RASTIC studied in this report appear to have a considerable net benefit to BR. The major civil-engineering benefits of weld straightening seem to be a reduction, in the CWR maintenance tamping requirement of approximately 9%, which is worth £1.47M/annum, and...
