I visited Shackerstone two years ago and back then 45015 looked a complete wreck. IIRC, as a result a court case over unpaid rent, the Railway Society acquired unexpected ownership of 45015, but show no interest in doing anything with it.I have seen suggestions online that 45015 at Shackerstone has a small about of asbestos in the boiler compartment, which is a concern and would cost a few bob to remove.
