The stations at Bala, Arenig, Trawsfynydd and Festiniog had two platforms, each with its own track.

[10] A fifth loop was provided between 1908 and 1950 immediately north of Cwm Prysor, when intermittent heavy military traffic to and from Trawsfynydd Camp was likely.

Local landowner Mr. Price of Rhiwlas objected to the construction of the line, and to appease him the goods shed was built to resemble a castle, with mock battlements and turrets.

[13][14][15]*[16] There was a small engine shed - a sub-shed of Croes Newydd - to the south east of the station.

[18] The station passed to the Western Region of British Railways on nationalisation in 1948.
