From the Steam Geek archives-
It’s a good day for steampunk at BoingBoing. As well as the pneumatic underground they also point to the Brighton and Rottingdean Seashore Elecric Railway, which operated between 1896 and 1901. The carriage was mounted on legs so that it stood 24 feet above the submerged rails. At high tide it could manage no more than 2 miles per hour and required a qualified sea captain, life boats and other rescue equipment at all times because it was travelling in the sea.
