At the beginning of the twentieth century the
Portmadoc, Beddgelert and South Snowdon Railway (PBSSR) endeavoured to build an electric railway to connect
Porthmadog with the village of
Beddgelert and the
North Wales Narrow Gauge Railway (NWNGR) at
Rhyd Ddu. This venture also obtained powers to build a line to
Betws-y-Coed and to connect with existing tramways and slate quarries. The PBSSR's life and history is complex, but two of its enabling
Acts made provision for extensions from the northern end of the NWNGR from to the quayside at Caernarfon. The Act of 15 August 1904 authorised a line northwards from Dinas running near the
LNWR's to line then veering westwards through the erstwhile
Nantlle Railway's Coed Helen tunnel then crossing a new bridge approximately on the site of the original Nantlle Railway bridge over the
Afon Seiont terminating on the quayside near the Harbour Offices. This route would effectively reinvent the Nantlle Railway's route from Dinas to Caernarfon Harbour. No source specifically mentions a station at this proposed northern terminus, but as the PBSSR was to be a mixed passenger and goods railway with designs on the tourist market, for it to go to the trouble of getting to Caernarfon without building a station would be very strange. In the event, nothing physical was done north of Dinas. An
Order of 8 July 1908 gave the company power to abandon the route through Coed Helen tunnel, replacing it with a line (effectively a street tramway) along St Helens Road in Caernarfon, terminating near the castle. In the application to Parliament (which had been made as long ago as 1905) the estimated cost was "£3241...with £500 allowed for a station located beneath the castle walls." A great deal of activity took place surrounding the PBSSR and the NWNGR, almost all of which was politicking, meetings, inquiries and business dealings. The only action on the northern extension from Dinas to Caernarfon was the sale of some land by the Caernarfon Harbour Commission to the railway. No building work of any nature took place north of Dinas and powers to do so lapsed in 1910. The onset of the
First World War stopped the machinations, but did not close them for good. On 18 October 1921 the Light Railway Commissioners opened a Public Enquiry into the whole question of narrow gauge railways in the Porthmadog-Beddgelert-Caernarfon area, not least in the light of significant unemployment. Caernarfon interests were in favour of the original aim of a through narrow gauge route from Porthmadog to Caernarfon, not least because the need to tranship goods and people at Dinas deterred traffic which even then was being lost to road transport. The LNWR supported all moves to build a unified line northwards from Porthmadog, but opposed a northern narrow gauge extension from Dinas. The commission's finding was to support the formation of the Welsh Highland Railway which would join the PDSSR and NWNGR to give a through route from Porthmadog to Dinas, but the northern extension to Caernarfon was not backed and thereby died. ==Modern times==
