The evolution of Blaenau's passenger stations was complex, with five different railway companies providing services to the area.
[5] One source states that narrow gauge services continued 'to a temporary terminus just short of Dolgarregddu'[6] No hint of its existence is given in the standard work on the F&BR.
The line through the site of the temporary station closed in 1961 but it was mothballed pending building the long-discussed cross-town link to enable trains to run along the Conwy Valley Line, through Blaenau and on to Trawsfynydd nuclear power station which was then being built.
In Spring 2016 the mothballed single track line still ran past the site to the former nuclear flask loading point.
On 21 September at least one regional newspaper reported that "Volunteers are set to start work this weekend on clearing vegetation from the trackbed between Blaenau Ffestiniog and Trawsfynydd."
