It was first opened on this site by
British Rail on the former
Taff Vale Railway in 1986 and is the location of the only
passing loop on the section of route north of , which had previously been singled by
British Rail in stages between 1972 and 1981. The current station replaced an earlier station of the same name when it opened in 1986. The original Ystrad station, which had operated since 1861, was renamed Ton Pentre when the new Ystrad Rhondda station opened approximately one mile further east along the line. This change reflected the continued development of the Rhondda Valley's railway infrastructure and the need to better serve the local community. The station was built on the route of the former Taff Vale Railway, which had originally reached Treherbert in 1856. The transformation works were part of a £1 billion investment in the South Wales Metro, described as the largest and most complex engineering project taking place in Wales. The Treherbert line was electrified in May 2024, and the first electric train services began operating in November 2024 using new Stadler Class 756 tri-mode trains. These modern trains feature improved capacity, air conditioning, Wi-Fi, and passenger information screens, representing a significant upgrade from the previous diesel rolling stock. ==Station buildings and facilities==
