Al, Helen and I spent a plesent Sunday afternoon exploring the world's largest miniature railway or is it the world's smallest public railway? We also took a trip up the old lighthouse at Dungeoness. However, we weren't able to visit the visitors' centre at the nuclear power plant because it's closed permanently.
The railways is quite cool. They have tiny steam locomotives running on 15" gauge track. However they are 1/3 scale representations of big locomotives and look really stunning.
