Lumo still aiming at December 2027 for Carmarthen to Paddington
Five Hitachi trains are on order. Five return trips a day are promised. GWR will still be on the same metals. Tickets are not on sale yet.
Lumo, FirstGroup’s open access brand, says the Carmarthen to London Paddington service will start in December 2027. The first five of 14 Hitachi Class 80x units ordered for First’s open access work are earmarked for this route. First Rail open access managing director Stuart Jones told Modern Railways in the spring that those five had to come first “because we have to get that operating as quickly as possible.”
The pattern is five trains each way a day. Stops listed are Carmarthen, Llanelli, Gowerton, Cardiff Central, Newport, Severn Tunnel Junction, Bristol Parkway and Paddington. One class of seating, free wifi, catering on board. First has talked about 100 direct jobs and about 50 million pounds of annual revenue after two years. Track access rights run to the end of 2037. They came with Grand Union Trains, which won the paths from the regulator in 2022 after a fight with GWR, then sold the rights to First in December 2024.
What you have now
Until those units arrive, west Wales still uses GWR and Transport for Wales. GWR already runs Paddington trains through Swansea to Llanelli, Pembrey and Burry Port and Carmarthen. TfW covers the local stops and the Heart of Wales line the other way. A cheap TfW hop Carmarthen to Llanelli can still be four pounds if you book it right. That is not London. London is still a change at Swansea or a GWR through train with GWR fares.
Lumo’s pitch is the same one it used on the East Coast: undercut the incumbent, fill empty paths, one class, no first class carriage taking up seats. Whether a Carmarthen departure can stay cheap once GWR answers is the test in 2028, not in a press line from 2026.
What it will not do
It will not call at Pembrey, Kidwelly, Ferryside or Whitland. It will not go to Milford Haven or Pembroke Dock. Labour’s Senedd manifesto talked about a separate Milford to London idea and money on the Milford to Carmarthen line. That is not this service. Gowerton gets a London train it does not have today. Llanelli gets a second operator on the long haul. Carmarthen becomes a London terminus again in name, 16 years after Arriva’s through trains faded from memory.
Open access lives on paths the regulator allows. GWR opposed Grand Union the first time. It will compete on price and paths when the Hitachi sets appear. TfW has also talked about its own trains toward Bristol. Three operators on the South Wales main line is better for a passenger in Llanelli than one. It is also three sets of delay attribution when a freight train fails at Newport.
When to look again
No public timetable exists yet. No tickets. Watch for a First or Lumo booking page in 2027, and for which of the five diagrams actually start in the December timetable change rather than slipping into 2028. The Chronicle will report the first reserved path and the first fare, not the brochure.
