If you've ever been to either Dewi Sant Hospital or been a student at the Treforest campus of the University of South Wales then it's possible you have seen these blocked-up tunnels. The tunnels, found at both sites, are the only reminders of a train line that ran under the Graig into Treforest more than 100 years ago.
It is hard to imagine Pontypridd having a second train line but that is what the reality was in the 19th Century. The railway passenger service started in March 1896 by Barry Railway, although the line itself had been in use since July 1889.
The station that was situated in Graig was renamed Pontypridd Graig in January 1922, while the current station was given the title of Pontypridd Central. We've taken a look through the archives at some of the pictures of the tunnel over the decades.

The Pontypridd Graig station was closed in May 1930 and the tunnel were left to rot. Most of the station became what is now the Dewi Sant Hospital which was built in the 1960s.
The only clues to what came before were the tunnel mouth itself and the stone above the tunnel which reads 'James W. Szlumper - Engineer, John Mackay - Contractor, 1888'. Below is how the station looked away from the tunnel.
