Discount Cardiff - Portsmouth train tickets

The best way to spend less on your Cardiff Portsmouth train ticket must be to have a railcard. While regional railcards exist in some areas, National railcards enable you to make savings on most rail fares across the United Kingdom. Everyone is eligible to at least one of the railcard, even non-UK citizens. National railcards available: 16-25 railcard, Senior discount card, Two together railcard, Family and Friends discount card and Disabled persons railcard.

The main benefit of purchasing a railcard is that you only need a few trips to break even.

You will need to buy at least £88 of train tickets in a year for the railcard to be worth the investment. It corresponds to the price of the card, thirty pounds, divided by the saving, thirty four percent. On every train that you purchase after that, you will spare money.

The price to buy a Disabled persons railcard is £20 while it will cost you £30 to have the 16-25, Two together, Family and Friends or the Senior railcard. All of them enable you to save 34% off most adult fares for one year.
