In recent times I have seen occasional comments about heritage railways being unable to trace or contact the owners, leaving them with a headache. If an owners dies, it cannot be assumed that they left the matter to an executor or probate to resolve. In other cases, owners have simply disappeared without leaving any details with the railway, often for many years. It is a particular problem if the item of rolling stock is effectively dumped on their site or an issues arises over rolling stock agreements or maintenance. What do heritage railways do in this situation?
