Sylfaen railway station, located in the tiny hamlet of Sylfaen on the A548, is an unstaffed request halt on the narrow gauge Welshpool and Llanfair Light Railway 2+3⁄4 miles (4.4 km) from the Welshpool Raven Square terminus. It has a short platform and waiting shelter.

Opened as Sylfaen Farm Siding in 1904 it was renamed 'Sylfaen Halt' on 1 February 1913. Sylfaen was closed to passengers on 9 February 1931.

Originally the halt had a short goods siding. Parcels could be left in a box and a special blast on the engine's whistle indicated items to be collected. The Great Western Railway withdrew passenger services in 1931. and the line closed completely on 3 November 1956.

By 1972 the line had been restored as far as Sylfaen. The station was furbished and provided with a passing loop for the beginning of the 2024 season.
