Train passengers are urged to check before they travel this weekend, as Great Western Railway warns services will be busier than usual as music fans head to London for big- events, and with industrial action also taking place, services between Swansea and Pembroke Dock have also been cancelled on Saturday (July 7).

GWR is warning customers heading in and out of London for this weekend’s big-ticket music events it expects trains to be busier than usual, with no additional services operating after 2300.

Customers heading home from the capital are being urged to travel on as early a service as possible, with engineering works and industrial action short of a strike restricting the number of late-night trains it is able to operate from London Paddington.

The industrial action by the Aslef union means services will be subject to late-notice cancellations and alterations.

Customers are advised to check before they travel and, to help people leaving London Paddington, tickets will be valid for travel on earlier services.

GWR Director of Performance and Train Service Delivery, Daryn McCombe, said: “If you’re travelling back from London Paddington either tonight, Saturday or Sunday night, please do catch an earlier train home if you can.

“Industrial action short of a strike and engineering works mean we’re not able to operate additional trains as we might normally and we’re expecting our later trains from Paddington to be extremely busy.

“The industrial action also means services will be subject to late-notice cancellations and alterations, so we would urge customers to check before they travel throughout the weekend.”

British Summer Time Hyde Park continues with Billy Joel tonight, Bruce Springsteen tomorrow night and Lana Del Ray on Sunday. Over the next two nights, Blur play Wembley Stadium, Iron Maiden are at the O2 and The Weekend at the London Stadium.

Elsewhere on the network, Castle Cary station is expected to be busy as music fans head for the NASS Festival (until Sunday), while those attending Bristol Pride Day tomorrow are reminded about engineering works affecting journeys between Gloucester and Yate.

“Industrial action short of a strike means we’ve also had to cancel services between Swansea and Pembroke Docks tomorrow,” added a spokesperson for GWR.
