Railway Remnants in Glamorgan
- The Barry Railway main line ran thru the present-day Glamorgan University (underneath the refectory) where it disappeared under a tunnel on the north side to burrow under Pontypridd. Its northern end was at Trehafod in the Rhondda, where now exists the Barry Sidings Countryside Park.
- A branch line of the Barry Railway cut eastwards across Walnut Tree Viaduct, north of Tongwynlais in Cardiff, where a couple of piers can still be seen. In the next valley, the stump of the Llanbradach Viaduct can be seen near the station of Llanbradach, north of Caerphilly.
