Dinas is a village near Tonypandy in the county borough of Rhondda Cynon Taf, Wales.
[1] Dinas is located in the lower Rhondda Valley about halfway between Treorchy and Pontypridd.
From here coal was carried by trams via Porth, Cymmer, and Trehafod to Pontypridd, where it was conveyed by canal to Cardiff.
Ten years later another devastating explosion resulted in the death of 63 miners.
[3] In 1841 the 4-mile long Rhondda branch line of the Taff Vale Railway was opened between Pontypridd and Dinas, eventually to be extended as far as Treherbert by 1856.
