Dolgoch[a] is a narrow gauge 0-4-0 well tank steam locomotive. It was built by Fletcher, Jennings & Co. and is one of the oldest locomotives still in active service. It was delivered to the Talyllyn Railway in 1866[2][page needed] and continues to run on this railway to this day.

Dolgoch holds an important place in railway preservation history as it was the only serviceable locomotive on the Talyllyn Railway when it became the first preserved railway to be operated by volunteers, in 1951. Dolgoch kept the railway going during this first season.[3][page needed]
