The Gwili Steam Railway operates a standard gauge preserved railway from Bronwydd (near Carmarthen) in South Wales along a short section of the former Carmarthen to Aberystwyth railway that closed for passenger traffic in 1965, the track being lifted in 1975.
The Gwili Railway was formed in 1975 and, by 1978, had purchased and rescued about eight miles of trackbed and was running an initial steam-hauled service on a one-mile section of it.
