The railway tracks of the Afan Valley are now used by cyclists and walkers. Many of the bridges used by the railways can still be seen. Other remains of the railways include:

The Refreshment Rooms at Cymmer - built for that purpose with a bar - once formed part of the Rhondda Swansea Bay Railway Station at Cymmer as illustrated on the previous page. The building with its platform is all that remains of the original station. Public opinion saved the building from being knocked down.

The Gelli Tunnel on the Rhondda Swansea Bay Railway at 128 metres long allowed links via a bridge to Blaengwynfi station on to the Rhondda valley and Treherbert. The tunnel was named after the Jenkins family of Gelli Farm.

The Tunnel Hotel at Blaengwynfi stands near the entrance to the Rhondda tunnel which is 1,340 metres long. Built in 1890 it was the longest tunnel in Wales and took three years to build. It provided a link from the Afan Valley to Blaenrhondda and Treherbert, a distance of 24½ miles.

The Cynon Halt, near Afan Argoed is the only formed railway station in the valley where both platforms remain. No trains today, just cyclists and walkers.
