The Dinorwic QH was a 0-4-0 narrow-gauge quarry locomotive used at the historic Dinorwic slate quarry in Wales. Designed for harsh industrial conditions, it featured four coupled driving wheels providing strong low-speed traction and excellent maneuverability on the quarry’s steep gradients, sharp curves, and rough, lightweight track. Compact, rugged, and easy to maintain, the QH type delivered reliable daily performance in one of the most demanding narrow-gauge industrial environments.
