Goods traffic through the ex-VoN High Level station ended in 1965 and the line fell into disuse, but in August 1973 it was reopened to release the former TVR line trackbed and station site for road improvements (including the removal of an inconveniently-located level crossing - the town bus station now occupies the site). All services were diverted onto the old VoN line via a new connection between the two lines near Cwmbach and then on through the old High Level station to regain their former route at Gadlys Junction. The new connection was carried over the River Cynon on a girder bridge that had previously been used to carry the defunct to branch line across the A40 road at Wheatley, Oxfordshire.
