This letter gives the Department of Transport’s decision on the request for a derogation for the core section of the Crossrail. This derogation would mean that the Control Command and Signalling (CCS) TSI for Conventional Rail (Commission Decision 2006/679/EC) (PDF, 1824 KB) would not be applied to the project. The letter confirms the request has been successful subject to conditions.
