GWR will operate nine additional services following Bruce Springsteen and the E Street Band’s evening gig on Sunday 5 May, however trains are expected to be very busy immediately after the event..
Three services will run to Swansea from 10.44pm, with six services to Newport travelling on to either Bristol Temple Meads or Swindon from 10.40pm.
In a repeat of the queueing system in place for other large-scale concerts such as Harry Styles in 2023, people travelling east towards Newport will be asked to queue on the square in front of Cardiff Central station, rather than from Riverside Car Park.
GWR Customer Service & Operations Director, Richard Rowland, said: “Principality Stadium is expecting nearly 50,000 people to attend the Bruce Springsteen concert this Sunday, many of whom will choose to do so taking advantage of the ease of travelling by train.
“Previous events on this scale have shown that our trains get extremely busy, and people will need to queue outside the station to board trains safely..
“We encourage all who are using these services to check journey times and connections at gwr.com/check and allow sufficient time to complete your journey home.”
Transport for Wales will also provide additional capacity where possible on routes in/out of Cardiff, but services are expected to be very busy.
Gates to the Principality Stadium open at 4.00pm and the concert is expected to finish around 10.30pm.
