The location of the former station was 13miles-66chains from Cadoxton South Junction (east of Barry) and just 31 chains (682 yards) further on to the north-west, is the south-east portal of the now bricked up 1323-yard Graig (or Pwllgwaun) tunnel.
Part of the former double line trackbed leading to the tunnel is now a car park associated with the University campus at Treforest.
The up line between here and Tonteg Junction was closed temporarily for the storage of American S-160 steam locomotives between October 1943 and September 1944.
Nothing remains of this station and the site is occupied by a police vehicle maintenance depot.
The main entrance was however situated approximately at the end of Hilda Street, Trefforest - some steps still remain.
