No. 1013 County of Dorset was a Great Western Railway 1000 Class or County Class 4-6-0 steam locomotive built in 1946 at Swindon Works. It was one of thirty examples of this class built between 1945 and 1947.
After the nationalization of Britain's railways in 1948 all 30 Counties continued to do useful work throughout the Western Region of British Railways, working on expresses to and from Paddington as well as more menial freight and parcels tasks. BR gave the Counties the power classification 6MT. Speedometers were fitted to the class from 1950 and modified double chimneys from 1956.
Withdrawals of the class took place between September 1962 and November 1964. No. 1013 was sold to Cashmore's Scrapyard in Newport where it was cut up in July 1964.
