No.2 ‘Dolgoch’

No.2 ‘Dolgoch’

“Dolgoch” was built in 1866 by Fletcher, Jennings & Co., but to a very different design to that of “Talyllyn”. It is an 0-4-0 tank engine with both a back tank (rear of the cab) and a well tank (between the frames). The long wheelbase allows the firebox to sit in front of the rear axle, with Fletcher’s Patent inside valve gear driven off the front axle, a particularly inaccessible arrangement. In increasingly decrepit condition “Dolgoch” continued to operate the service single-handedly until 1952 when “Edward Thomas” became available and was then the subject of a prolonged overhaul between 1954 and 1963.

As part of an overhaul that concluded in late 1999 it was fitted with air braking equipment, being the final TR steam loco to receive the modifications. A new boiler, built as close as possible to the original design, was fitted in 2011. In 2015, along with sister locomotive “Talyllyn”, it was repainted in ‘Indian Red’ livery which is thought to be a close approximation to the colour carried by these locomotives when delivered by Fletcher Jennings in the 1860s.

“Dolgoch” most recently re-entered service in May 2023 following a short overhaul, painted in the deep bronze hues of the “TR Standard Green” livery.
