Train disruption

The biggest rail union, the RMT, has announced strike action that will affect rail services on Saturday, September 2, and Aslef has announced a strike for Friday, September 1.

On strike days, a reduced, revised timetable will operate across several train operators, including GWR. Many parts of the GWR network will have no service at all. Services will only operate for a limited period, starting later in the morning and finishing much earlier in the evening

Those travelling to and from Cardiff should note there will be no GWR return services on Saturday evening and customer should seek alternative means of travelling. Visit for more details.

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.

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 make use of the dedicated Shopping Park & Ride sites at Pentwyn or County Hall. City centre car parks are also available: 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.
