How to book cheap train tickets from Cardiff to Swansea

Travelling in off-peak train times

Taking advantage of Off-Peak train tickets is another effective way to save on your train journey from Cardiff to Swansea. These tickets are generally cheaper and can be used during quieter periods, typically outside of morning (06:30-09:30) and evening (16:00-19:00) rush hours on weekdays.

Using the Railcard for 1/3 off

Railcards offer discounts of up to 1/3 on most tickets. There are various types of Railcards catering to different types of travellers, such as the 16–25 Railcard, the Family & Friends Railcard, and the Senior Railcard. For more information on Railcards and how they can help you save, visit Railcards here.

Split Tickets to save an average extra 30%

Another option to consider is splitting your tickets, which can save you around extra 30% on fares. Instead of purchasing a direct ticket from Cardiff to Swansea, you can split the route into two legs: A to C and C to B. This often turns out to be more affordable than buying a direct ticket, and you won’t even need to leave the train… or often your seat!.

Book in advance to save an average of 61%

Advance Tickets are typically released up to 12 weeks before the travel date and can offer significant savings compared to tickets purchased closer to departure. By planning your trip from Cardiff to Swansea ahead of time and booking your tickets early, you can potentially save up to 61% on your travel expenses.

Group travels to save 1/3
