The inclined plane at Hay, which was last used in 1894, was restored in 1968 and again in 1975, including the reinstatement of rails. There are the remains of a building with a chimney stack at the top of the incline, which was probably the engine house. A grade II listed bridge carries a road over the bottom of the plane. In 1967, the Dawley Development Corporation, who were responsible for Dawley New Town, later renamed Telford, decided that important industrial sites at Coalbrookdale, Coalport, Blists Hill, and several others, should be preserved and restored. Blists Hill Open Air Museum was opened to the public in 1973, and has since become the Blists Hill Victorian Town.
