 The canal was sold in 1829 by George Templer, along with the Stover estate and the quarries and tramway, to Edward St Maur, 11th Duke of Somerset (1775-1855).When plans to build the Moretonhampstead and South Devon Railway were proposed, his son the 12th Duke of Somerset, who by then had inherited the Stover estate, sought to sell both the canal and the trackbed of the derelict Granite Tramway to the fledgling railway company.It was duly sold for £8,000 on 4 June 1862, by which time the section above Teignbridge was effectively redundant, and so the railway company was not required to maintain it.
