Pontypridd, Caerphilly and Newport Railway

The Pontypridd, Caerphilly and Newport Railway was built to bring the coal output of the Aberdare and Rhondda valleys directly to Alexandra Docks at Newport.

It was a little over 5 miles (8 km) in length, running from Pontypridd to a junction near Caerphilly; from there to Newport existing allied railways conveyed the mineral trains. A passenger service was operated later, not stopping intermediately on the line, until in 1904 a railmotor service was started, calling at new low-cost intermediate stopping places.

The line closed to passengers in 1962, and to freight from 1965.
