How to book cheap train tickets from London to Carmarthen

Season Tickets for frequent travel

If you frequently travel between London and Carmarthen, a Season Ticket allows unlimited travel between these stations and is available for various durations, such as weekly, monthly, annual, or flexi. Enjoy the convenience of not having to buy a ticket for each journey, as well as significant savings.

Network Railcard for South East England

For only a small annual fee, you can save 1/3 on most fares in South East England, including routes in and out of London, with the Network Railcard. Covering both standard and off-peak tickets, this railcard is particularly beneficial for those who travel regularly within this region.

Traveling in off-peak train times

We recommend buying train tickets from London to Carmarthen during off-peak hours. These times are usually before 06:30, between 09:30 and 16:00, and after 19:00 on weekdays, as well as all day on weekends and bank holidays. Choosing Off-Peak train tickets means benefiting from cheaper fares and less crowded trains, making your journey more enjoyable.

Get 1/3 off with a Railcard

You can choose a Railcard to help you save up to 1/3 on fares from London to Carmarthen for various reasons, such as your age (including the 16–25 Railcard or Senior Railcard) or options geared towards group travel (Family & Friends Railcard and Two Together Railcard). Discover more here.

Split tickets to save an average extra 30%

Another option to consider is splitting your tickets, which can save you around an extra 30% on fares. Instead of purchasing a direct ticket from London to Carmarthen, 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%

Did you know that purchasing Advance Tickets can significantly reduce your travel expenses? On average, these tickets can save you an impressive 61% on fares. The best part is that the earlier you book (ideally up to 12 weeks in advance), the greater the savings!

Travel in a group to save 1/3
