Edward Thomas is a narrow gauge steam locomotive. Built by Kerr Stuart & Co. Ltd. at the California Works, Stoke-on-Trent in 1921, it was delivered new to the Corris Railway where it ran until 1948. After that railway closed, the locomotive was brought to the Talyllyn Railway in 1951, then restored, and remains in working order at the heritage railway. It has carried the operating number 4 under four successive owners.
