 The project was opened by the last survivor of the dam disaster, Fred Brown, who on that night lost his mother and his younger sister.The construction of Eigiau dam had been facilitated by the construction of the Eigiau Tramway, which largely followed the route of the Cedryn Quarry Tramway from Dolgarrog.The incline was upgraded (and the lower section re-aligned), enabling steam engines to reach the starting point of the tramway, near Coedty reservoir.
