[1] The first section of the Taff Vale Railway (TVR), between Cardiff Docks and Navigation House (now Abercynon) was opened on 8 October 1840.

[3] As well as being served by trains between Merthyr & Cardiff on the main TVR route, it also acted as the junction station for the Llantrisant and Taff Vale Junction Railway branch line from its opening to passenger traffic in 1875.

[3] Services to both Cardiff and Barry on this route ended on 10 September 1962, whilst that to Llantrisant had been withdrawn a decade earlier (on 31 March 1952).

[3] During Monday–Saturday daytimes, there are usually six trains an hour from Cardiff Central, two to each of Treherbert, Merthyr Tydfil and Aberdare, all stopping at Pontypridd.

[6] A reduced service operates on Sundays (2-hourly to all three northbound destinations, 3 trains every two hours to Cardiff and beyond).
