The Great Western Railway (GWR) 2600 or Aberdare class was a class of 2-6-0 steam locomotive built between 1900 and 1907. They were a freight and light mineral development of the 3300 Bulldog and 4100 Badminton classes, both 4-4-0 locomotives. Therefore, the design was adapted and became a 2-6-0 type; the resulting locomotives were used for hauling coal trains between Aberdare and Swindon.
