The railway line between Machynlleth and Pwllheli was authorised to be built by the Aberystwith and Welsh Coast Railway (A&WCR) on 22 July 1861.
During construction, the A&WCR amalgamated with the Cambrian Railways, this being authorised on 5 July 1865 and effective from 5 August 1866.
The section between Barmouth and Afon Wen opened on 2 September 1867, and Penrhyndeudraeth station opened the same day.
