Tornado - repair update 17/04/2018 The A1 Steam Locomotive Trust would like to apologise for the disruption caused to passengers travelling on ‘The Ebor Flyer’ on Saturday 14th April 2018 and passengers on other trains impacted by No. 60163 Tornado’s breakdown. The locomotive came to a stop just south of Sandy with a broken combination lever. Investigations have so far revealed that this was due to the middle piston valve overheating and binding in the valve chest. The root cause is not yet fully clear, but it is likely that insufficient lubrication was an issue. Investigations continue to establish the cause of failure in the lubrication system and any contributing factors. Tornado has run many miles since winter maintenance with no obvious issues in this area. Whilst we have been asked if the higher speed was a factor in the failure, at present we believe it not to be. It probably happened slightly earlier in the journey than if running at lower speed, but it most likely would still have happened.
