[6] The evolution of Blaenau's passenger stations was complex, with five different railway companies providing services to the area.
This was the first steam-hauled passenger service in Britain to use tracks of less than Standard Gauge, with the line carrying a quarter of a million people in its first year of operation.
[7] The station's first stationmaster was Mr John Lloyd,[8] the initial service was five trains to and from Portmadoc each day except Sunday.
[13] The original shed housed the railway's "Top Shunter",[14] a locomotive long given to providing unofficial services to lineside dwellings.
[18] Trains from Portmadoc alternated between the two stations,[19] but Duffws was better sited for passenger traffic,[7] so Dinas closed in 1870.
