Welcome to the Clifton Rocks Railway restoration project official site. The project is dedicated to preserving one of Bristol's hidden gems. Buried within the cliff-face of Avon Gorge is the Clifton Rocks Railway. This impressive feat of engineering first opened in 1893 and has a long and storied history. Now the railway is undergoing extensive restoration to turn the location into a museum that will offer the public a peek into the Clifton Rocks Railway's unique past.
