Dolgarrog railway station is an unstaffed halt, and a request stop, on the Conwy Valley Line from Llandudno Junction to Blaenau Ffestiniog.

The station was built by the LNWR in 1916 to provide sidings and an interchange facility with the Dolgarrog Railway, a short-standard gauge industrial line, built by the Aluminium Corporation to serve Dolgarrog village and the aluminium works that are about a mile from the station on the west bank of the river.

[5] Following serious flood damage to the line in multiple locations in March 2019, services from this station were suspended for four months and replaced by buses whilst major infrastructure repairs were carried out.

The damaged platform was removed and the line reopened to traffic on 18 July 2019, but with Dolgarrog station remaining closed.

On 22 November 2019 the line closed again for three weeks for a new platform to be built at Dolgarrog and rock bolts to be installed in Ffestiniog Tunnel, reopening on 15 December.
