Pantperthog

Llwyngwern was a station on the Corris Railway in Wales, built to serve the hamlet of Pantperthog and the residents of Plas Llwyngwern, a house where a daughter of the 5th Marquess of Londonderry lived with her husband. Although the Plas was in Montgomeryshire, the station was across the Afon Dulas in Merionethshire. The station was built at Llwyngwern, rather than at Pantperthog, because there is a very tight bend and a steep gradient on the railway at Pantperthog. The station was opened on 1884, and closed with the end of passenger services in December 1930.: 7
