With the increase in population, transport links began to improve in the Rhondda. This was hampered by subsidence caused the mining underground, which resulted in the roads of Porth Square sinking by eight foot. In 1860 a two horsed omnibus service was introduced between Porth and Pontypridd, but was replaced by a system of horsedrawn tramcars in 1888. Although the tramline and subsequently the railway had passed through Porth for two decades, servicing the collieries, it was not until 1861 that the village had its first railway station; and a passenger service did not commence until January 1863.
