Valley Lines (Cardiff Railway): former routes and current operators
Valley Lines was the former Cardiff-area suburban railway brand, operated through the Cardiff Railway franchise. Its network forms an important part of the ancestry of today’s Transport for Wales services and South Wales Metro.

Operator history and changes
The Cardiff Railway franchise started in 1996 under Prism Rail. Passengers generally knew its services as Valley Lines: a network centred on Cardiff and the valleys to the north, with links towards the coast. It was a separate franchise from Wales & West, even though the two businesses connected at Cardiff and later shared an owning group.
National Express took over Prism’s rail interests, and Valley Lines was brought into the interim Wales & Borders business formed in October 2001. Arriva subsequently took over the wider Wales and Borders franchise in December 2003. The Valley Lines name therefore identifies a particular stage in the organisation of the Cardiff railway, rather than a second train company operating alongside Transport for Wales today.
Former routes and principal stations
Historical Cardiff and valley routes
The former network connected Cardiff with valley communities. A map of these branches is useful historical context, but should not be used as a present through-service diagram.
Historical coastal and city connections
Services also linked Cardiff with nearby coastal destinations and the bay branch. Interchanges and termini must be checked against the current timetable.
Travelling on these routes today
Use Transport for Wales for present journey planning. The South Wales Metro programme has changed infrastructure, trains and service arrangements, so select your actual travel date rather than reproducing an old Valley Lines connection. Cardiff Central and Cardiff Queen Street are separate stations with different roles: confirm which one appears in the itinerary, particularly when connecting from an intercity train to a valley branch.
Tickets and journey choices
Valley Lines fares and local promotions are archived material. Check the current validity of any local rail, multimodal or concessionary product, including the stations and times it covers. A product described as valid in the valleys does not automatically cover every onward journey across South Wales or every connecting bus.
Accessibility and assistance
Use current TfW station and assistance information, including notices about Metro engineering work. Check the accessible route through the particular Cardiff interchange and whether replacement transport is involved. Historic descriptions of diesel trains or platform facilities cannot establish the boarding arrangements for today’s trains.
