Cwm-y-Glo railway station served the village of Cwm-y-glo, Gwynedd, Wales, at the north-west end of Llyn Padarn. The station was closed for regular passenger services in 1930 but trains passed through until September 1964. The station lay on the nine mile LNWR branch line between Caernarfon and Llanberis which was established by the Caernarvon and Llanberis Railway Act 1864. The Summer 1939 Working timetable shows that some excursions made unadvertised stops at the station.
