I understand that it would be a big problem for Dover Priory, but will talk to the station manager (a different one now to last time); he loves old strains, especially steam engines, so it might have legs.
Should this ever come about, there would need to be buses at Dover Priory station ready to take people around Dover to the historic sites - it would also depend of course on how long it woud be here; it may also of course give people a taster o just how great Dover is and want to come back for a few days.
