 The line 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.The line past the site of Tan-y-Manod station, the engine shed and transshipment sidings reopened on 24 April 1964, but none of Tan-y-Manod's facilities were brought back to life.The line closed again in 1998 as the nuclear plant was being decommissioned.
