These tickets can be purchased well in advance, often at a discounted rate if you're strategic with your timing. There are numerous online platforms and railway websites that allow you to compare prices, ensuring that you secure the best deal. Always keep an eye out for peak and off-peak times, as this can significantly affect the price of your ticket.

The earlier you book, the better the deal you’ll likely find. If you're looking to save, avoid traveling during peak hours—typically weekday mornings and early evenings. Instead, choose a midweek journey or travel outside these congested periods.
