Withdrawal and preservation The Class 306 trains were withdrawn in the early 1980s, with 306017 preserved at Ilford depot. It had been repainted in a near original green livery, albeit with a yellow warning panel on the front to comply with then-current safety regulations. In the early 2000s, it was restored to operational condition by First Great Eastern. The unit was in store at MoD Kineton awaiting the resolving of issues such as asbestos contamination. The contamination was removed at Eastleigh Works and the unit was transferred by rail to the East Anglian Railway Museum in June 2011 for display as an exhibit, under a 4-year loan agreement from the National Railway Museum. It was moved to Locomotion: the National Railway Museum at Shildon in October 2018 so it can be assessed before restoration. It is scheduled to move to York when space becomes available.
