Aerial Ropeway
In Claughton, Lancashire, the Forterra brickworks produces 50 million bricks a year, from shale that's quarried a mile and a half away. To get that shale to the brickworks: the last aerial ropeway in the country. It uses no power, moves 300 tonnes a day. These used to be common: but now, the last one will be gone by 2036.
