Dolbadarn - This Hunslet loco, built in 1922, was one of two intended for switching at Port Dinorwic. It worked the port until 1936 when it was sent over to Dinorwic quarry. Prior to 1946, when it was given the name Dolbadarn, it was just known as Number 2. Also purchased by the Llanberis Lake Railway in 1969 when the quarry shut down it was in good enough condition to be serviceable for the railway's opening in 1971. The engine received a new boiler in 1997 - 1 May 2000 Steve Armitage.
