The first thing to do is buying early. The sooner you buy, the more likely you are to secure a cheap ticket. Train tickets are often discounted for advance sales and the price ramps up closer to the departure of the train. Buying a train ticket at the station on the day of travel is usually a sure way of paying full fare.
The second tip is to try and buy online. Online ticket providers normally have very good deals and this can represent a significant saving. It is also a very easy and time saving way to buy your cheap train ticket.
The third tip is to buy an economy or saver ticket. If you want a cheap ticket, there is no point in travelling first class!
The fourth tip is to travel at non-peak times. Peak time travel is often more expensive because commuters who are travelling to work are out in force. Often travelling after 9.30am is cheaper then before. And it’s a lot more comfortable with less crowded trains.
And finally, try and buy a ticket with a fixed time. Open or flexible tickets are normally charged at a premium. Tickets with a fixed departure time are normally cheaper. Just don’t miss the train!
