The rolling stock preserved on the South Devon Railway is used to operate passenger services on the railway and for its maintenance. Other items are displayed for their historic interest or are awaiting restoration.
The South Devon Railway (SDR) is a heritage railway in Devon, England. Originally a branchline to from between 1872 and 1962, it was reopened by the Dart Valley Railway from near Totnes to in 1969. It was sold to the non-profit South Devon Railway Trust in 1991.
The SDR's collection includes many examples of steam locomotives typical of Great Western Railway types that used to work in Devon, also other types of steam locomotives and a number of diesel locomotives. The most notable locomotive on display is Tiny, a South Devon Railway 0-4-0vb shunting locomotive which is in the museum at Buckfastleigh station. This is the only original broad gauge locomotive still in existence in the United Kingdom.
There are a number of historic coaches in use including two 'GWR Super Saloons' coaches once used for trans-Atlantic liner passengers, and several auto coaches that were used on small branch lines such as this.
The engine sheds and workshops are at Buckfastleigh. Wagons used for maintaining the line are mostly kept at Staverton railway station and some rolling stock is stored at .
Many of the steam locomotives operating on the South Devon Railway are Great Western Railway (GWR) designs which would have worked on the line and nearby. There are also several locomotives from industrial facilities such as quarries and gas works, including some from locations in Devon.
