The Rhymney line is probably most well known for the 37/0 and /4 operated services during the early 21st Century. This era is when this route would be set. As well as the main part of the route from Penarth to Rhymney, the short branch off to Cardiff Bay as well as the 3 mile Coryton branch would be included. At the time the majority of services in the area were operated by the infamous Class 142/143 'Pacers'. The Cwmbargoed Colliery would also be included with Class 66's operating most if not all services to and from the colliery.
