Dandy waggon : ウィキペディア英語版 | Dandy waggon
The dandy waggon is a type of railway carriage used to carry horses on gravity trains. They are particularly associated with the narrow gauge Festiniog Railway (FR) in Wales where they were used between 1836 and 1863. == The challenge == The challenge on the FR was to move slate from an elevated location to a harbour for shipping, in this case from Blaenau Ffestiniog to Porthmadog, Wales. In 2006 this is a 28-minute drive over 11.9 miles (19.1 kilometers), but in 1832 it was a remote mountain area. The railway was laid on an average grade of about 1 in 80. Trains running downhill were powered by gravity, with 3 stops. The total journey time was about an hour and a half. Trains were moved uphill by horses until 1863, the journey taking almost 6 hours. It was therefore necessary to find a way to bring the horses back down again.
