 From 1749, iron from Pentyrch was initially transported to the works using pack-horses, then tub boats were used on the Taff passing onto the feeder via a lock at Radyr Weir. Parts of this lock can still be seen beside the feeder sluice. In 1815 the tub boats were discontinued and a tramway built along the Taff. There is a public picnic site by the Radyr weir.
