GWR steps in to rescue stranded coach passengers as M4 closure set to cause chaos

With the closure of the M4 motorway set to cause chaos for the next two weekends, train operator Great Western Railway (GWR) has stepped in to rescue National Express bus passengers, with an offer of free, fast train transport.

A 13 mile stretch of the key M4 road corridor between London, South Wales and the West of England will be closed from 9pm Friday 12 May to 6am Monday 15 May.

The major road works are also expected to cause further chaos for road users between 9pm Friday 19 to 6am Monday 22, and again for a long weekend in mid-June.

Those wishing to avoid the slow road, and holding a valid National Express ticket purchased before Tuesday 2 May for travel on any of the dates affected between London and the West of England (passengers will need to show proof of purchase), will be able to travel on any equivalent GWR rail service. Visit for full terms and conditions.

GWR Head of Communications Dan Panes said: “Even with significant infrastructure work continuing in preparation for new Intercity Express Trains later this year, the GWR network is still very much open for business as usual. Don’t be a slowcoach, come and join us and get to your destination quicker.”

*Advance single fares on GWR are still available between:

  • Bath and London Paddington for £17
  • Bristol Temple Meads and London Paddington for £17.50
  • Bristol Parkway and London Paddington for £17.50
  • Cardiff and London Paddington for £22
