Railcards are discount cards that help reduce train travel costs in the United Kingdom, and they are very popular with expats who use trains regularly. For expats, railcards typically offer around one-third off most rail fares and are available for different groups, such as adults aged 16–25, people over 60, families, couples, or frequent travellers. Expats in the UK can usually buy a railcard online or at train stations, and most cost an annual fee that quickly pays for itself after a few trips. Railcards can be used when booking tickets online, at ticket machines, or at ticket counters, but they must be carried (physically or digitally) when travelling. Expats in the UK should note that railcards often have restrictions during peak hours, especially on weekday mornings. Using a railcard is one of the easiest ways for expats to reduce the high cost of UK train travel.
