Croeso, Llinellau Craidd y Cymoedd!

A couple of hours ago, we released our latest map of the Core Valley Lines, covering the branches to Treherbert, Aberdare and Merthyr Tydfil, with services operated by Transport for Wales. The route to Treherbert is currently closed and will be opening in early 2024, but the rest of the routes show signal aspects, route indications and importantly, train movements.

These routes are signalled and maintained by TfW from the Core Valley Lines Integrated Control Centre, the CVLICC, at Taffs Well. The operation is similar to other parts of non-Network Rail infrastructure such as the East London Line, where train movement and signalling status indications are sent to Network Rail’s systems.

We are starting work on adding the routes to Rhymney and Coryton, including Cardiff Queen Street in to a separate map.
