Train disruption

There is a train strike planned for Saturday, September 2 and rail companies recommend checking your journey before you set out as there could be some alterations and cancellations to services on Sunday.

Please note that journey planners will be up-to-date around seven days before travel. Please visit the respective train companies’ websites for the latest information, including

There are no Transport for Wales (TfW) services all day between Treherbert and Pontypridd due to engineering work for the South Wales Metro. The rest of the TfW timetable will be operating as normal but trains between Newport, Cardiff and Swansea are expected to be busier than usual as a result of the industrial action taking place at other operators.

TfW is advising people only to travel by rail if their journey is essential on the South Wales main line between Carmarthen and Newport and between Cardiff and Lydney. Please plan ahead and check full times on the TfW website and online journey planners before you travel. Where services are running, they may be subject to late-notice changes.


Bus services will be diverted while the city centre road closures are in place. Please visit the relevant bus operator's website for more information about your specific bus routes.

National Express coaches will use Sophia Gardens as usual. 

Can you cycle or walk?

Those who live locally in Cardiff may want to travel by bicycle or walk. Research shows that 52% of car trips made in the Welsh capital are less than 5km. This is a distance that can be comfortably cycled in 20 minutes.

We also know that 28% of Cardiff residents who currently do not cycle would like to do so.When the roads are congested this makes cycling an even more attractive option as travel by bicycle would be quicker than a car during rush hours or during big events.

Shopping Parking

Shoppers are advised to use the city centre car parks: North Road Car Parks, St David's Shopping Centre, John Lewis, Capitol Shopping Centre, and NCP (Adam Street, Dumfries Place and Greyfriars Road.)

Disabled parking

Disabled drivers are advised to use Sophia Gardens. Disabled parking is also available at various private car parks. Please check individual websites for availability.


St Mary Street taxi rank (outside the old House of Fraser store) will not be affected by these events.
