DMUs were gradually introduced to services from 13th January 1958, using Class 116s. The 6 ½ mile branch also saw some through trains to places such as Pontypridd, Cardiff Queen Street and Cardiff Bute Road.
The rear of the Improved Services leaflet was a map.
The passenger service on the branch ended in June 1964, but it remained open for colliery traffic, allowing a number of DMU railtours to run over the line.
In the Passenger Services Western Region timetable it was Table 126 (0.3 mb pdf).
