Great Western Railway has partnered up with Seatfrog to launch Secret Fares, which will offer huge savings of up to 50% for passengers.

The trial offers mystery departure times between London and South Wales at reduced prices.

Passengers can set their preferred date and time window (morning, afternoon, or evening) and will receive train details 24 hours before departure.

Some example fares include:

  • London Paddington to Cardiff: £15
  • London Paddington to Newport: £15
  • London Paddington to Swansea: £23

Tickets can be booked 3 months in advance and up to 5 days ahead of travel.

Passengers should be aware that tickets are not refundable and railcard discounts do not apply.

The trial will be running until the 31st March 2026, and provided it is successful, it will be rolled out to other locations.

For further information, passengers can visit Great Western Railway’s website.

Secret fares can be booked here or through the Seatfrog app.

“At Seatfrog, we believe in giving people the best journey for their money. With this partnership with GWR, we’re taking our mission a step further – unlocking huge savings on popular routes between London and South Wales, simply by offering flexibility. It’s about giving people more choice: pick a date, a time-window, and enjoy travel that’s kinder to your wallet – no compromise on the experience. We’re excited to partner with GWR to make rail travel more accessible, more affordable, and more in tune with what passengers really want.”
