Purbeck Mineral and Mining Museum priority was to improve interior displays. The plan is now complete and now one of its main priorities is to restore skew arch bridge over the Swanage Railway and to enable access to Norden South, this will allow the Museum with the possibility of expanding the 2ft gauge railway and operating a passenger service and demonstration clay trains on special event days.
