The Gwili Steam Railway is a preserved Standard Gauge Steam Railway that operates from Bronwydd (near Carmarthen) in South Wales along a short section of the former Carmarthen to Aberystwyth railway. 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. The Gwili Railway has the distinction of becoming the first standard-gauge preserved railway to operate in South West Wales when it re-opened the one-mile section of the Carmarthen-Llanpumsaint route from its base at Bronwydd Arms, three miles north of Carmarthen. Since then, the railway has expanded to Danycoed and the company continues to hope to expand to Llanpumsaint.
A great family attraction the railway hold special events such as Thomas the Tank Engine themed days where the children can meet 'Thomas', 'Haulwen', 'The Fat Controller' and other characters. As well as all the fun of a working railway, visitors can enjoy live 'Covent Garden' Street Entertainers,
