Llandyssul (previously Llandyssil) was a railway station near the village of Llandysul, West Wales, on the originally broad gauge Teifi Valley line of the Carmarthen and Cardigan Railway.

The Teifi Valley Railway was originally conceived as a 7 ft 1⁄4 in (2,140 mm) broad-gauge line between Carmarthen and Cardigan.

It was converted to standard gauge (4 ft 8+1⁄2 in (1,435 mm)) by 1872.

The line was purchased by the Great Western Railway and extended to a terminus at Newcastle Emlyn in 1895,[2] The GWR did not build the line on to Cardigan and Newcastle Emlyn remained the terminus.

The old station had a stationmaster's house, cattle pens, a large goods shed, weighing machine, a signal box, etc.
