Following the recent issues with the AWS system on Tornado we are pleased to be able to report that the issue has been resolved. As an intermittent fault it was not easy to diagnose, nor had such a fault occurred previously on Tornado or any other locomotive fitted with the same system. We are grateful to Sharpe Engineering Solutions, Locomotive Maintenance Services and Thales for their help in diagnosing the problem.
A minor modification to the electro-pneumatic system has now resolved the issue.
