Pont Llanio railway station was a railway station in Wales on the former Carmarthen to Aberystwyth Line near Llanddewi Brefi. The railway station was built with only a single platform and building on the up side. The platform, small goods shed in the former yard and a cast-iron water tank was situated next to a creamery, built near the station in 1896. Producing 5 tonnes of butter per week by 1905, regular milk train services to the later Milk Marketing Board-owned plant allowed distribution all over the United Kingdom.
