 During the National Eisteddfod held in Pwllheli in 1925, the tramway was packed to capacity.On 28 October 1927 a storm over the north Wales area drove the sea inland over half a mile along the Embankment Road, and a long section of the tramway between Carreg-y-Defaid and Tyddyn-Caled was swept away.The Andrews' Estate announced  that the main section of the tramway would not reopen, although the Cardiff Road section within Pwllheli (between the West End and Ala Road) did run in summer 1928 .
