'Lost' Rhondda Tunnel keystone unveiled
A relic of Wales' largest tunnel has been moved to a new home after being presumed lost for many years.
The keystone which stood at the entrance to the Rhondda Tunnel was unveiled at nearby Treherbert station.
The tunnel closed in the late 1960s after the sweeping cuts to Britain's railways carried out after the Beeching Review.
It runs for more than three kilometres between Blaencwm in the Rhondda to Blaengwynfi in the Afan Valley.
Campaigners want to reopen it as a cycle track - which would make it the second longest enclosed track in the world.
The Welsh Government is carrying out a study into how feasible the plans are.
The Rhondda Tunnel Society says getting the stone restored and into its new home marks 'step one' of its hope of reopening the tunnel.
