This is a list of past and present rolling stock used on the Talyllyn Railway (Welsh: Rheilffordd Talyllyn), a 2 ft 3 in (686 mm) narrow gauge preserved railway line running for 7.25 miles (11.67 km)[1] from Tywyn on the Mid-Wales coast to Nant Gwernol near the village of Abergynolwyn. The line was opened in 1866 to carry slate from the quarries at Bryn Eglwys to Tywyn, and was the first narrow gauge railway in Britain authorised by Act of Parliament to carry passengers using steam haulage.[2][3] Despite severe under-investment,[4] the line remained open, and in 1951 it became the first railway in the world to be preserved as a heritage railway by volunteers.[5][6]
When first opened, the railway owned two steam locomotives, Talyllyn and Dolgoch, and five carriages, including one brake van. There were no additions to the rolling stock until the line was taken over in 1951.[note 1] Two ex-Corris Railway locomotives were then purchased from British Railways, and subsequent additions have brought the total up to six steam locomotives, four diesels and twenty-three carriages. As of 2023[update], Boston Lodge Works is constructing three bogie carriages, one composite with disabled access and two third class, numbered No. 24 to 26. The first of these, No. 24, was delivered to the railway in August 2023.
