Germany's Wuppertal Suspension Railway, or Electric Elevated Railway, is a hanging railway which runs along the Wupper Valley in the Ruhr. Built over 100 years ago, the unique monorail straddles the Wupper River and is a serious part of the region’s transport infrastructure, carrying over 20 million passengers a year. It runs along a route of eight miles at a height of 39 feet and at one point crosses a motorway. Ffestiniog Travel
offers a Trams & Trains of Northern Germany holiday which takes in the railway.
