Rail operator Great Western Railway (GWR) will provide more than 40 trains and nearly 20,000 seats after Ed Sheeran's three concerts at the Principality Stadium later this week.
GWR will operate 15 services from Cardiff Central after 22.45 on both Thursday and Friday night this week and a further 10 services on Saturday night.
Based the queueing system for this year’s Six Nations fixtures, people travelling to Newport after the game will be asked to queue on the square in front of Cardiff Central Train Station, rather than from Riverside car park.
The train company is advising passengers keep checking social media for the latest information on queuing times.
On Thursday and Friday, GWR will run six services to Swansea from 22.53, two inter-city express services to Newport at 22.56 and 23.25, plus seven services to either Bristol Temple Meads or Bristol Parkway from 23.13.
On Saturday it will operate four services to Swansea from 23.00, two services to Newport at 22.58 and 23.09, and four services to both Bristol Parkway and Bristol Temple Meads from 23.22.
With band My Chemical Romance playing at the nearby Sophia Gardens Cricket Ground on Saturday night, this will put further demand at Cardiff Central.
GWR customer service and operations director, Richard Rowland, said: “We’re doing all we can to help customers home following these concerts and we are pleased to be able to provide these additional services.
“But Cardiff Central is going to be especially busy after the gigs and we would encourage customers to check journey times and allow sufficient time to queue to board trains safely.”
Transport for Wales planning and performance director, Colin Lea, said: “With more than 50,000 people expected at the Principality Stadium each night, services in and around Cardiff will be very busy, so we kindly ask people plan ahead, check the latest timetables and leave plenty of time for journeys.
“We’ve paused evening improvement works on the Valleys lines to help more customers to get home by train after the event and we are strengthening services where we have trains and crew available.
“Colleagues will be working hard to assist everyone to get home safely and we would advise customers to familiarise themselves with the post-event queuing system and make sure they are prepared for the possibility of extended waiting times.”
