Lost Tramways of England [EPUB ebook] 
Devon and Cornwall

The far south-west of England possessed four 3ft 6in gauge electric tramways serving Camborne and Redruth, Plymouth, Torquay and Exeter. Each of these had a different character. The Camborne & Redruth saw significant freight traffic, which persisted after passenger services ceased. Plymouth was served by three different operators at one stage before the corporation took over. Torquay made use of the unusual Dolter stud system whilst in Exeter the trams had to make their way through the narrow mediaeval streets.
