Frequently asked questions
Is it better to buy on Trainline or on Renfe's official site?
If you are only travelling with Renfe, buying direct in its official app is usually cheaper because there is no service fee. Trainline is better when you want to compare Renfe with Ouigo or iryo in the same search, or when you are crossing several European countries with different operators, even though it may add a small fee.
Which app finds the cheapest high-speed tickets in Spain?
Trainline is the one to use for comparing prices, because it shows Renfe, Ouigo and iryo fares for the same route on a single screen. Prices swing a lot depending on how early you book and the time of day, so buy weeks ahead and stay flexible on departure time if you want the lowest fare.
Can I buy train tickets for the whole of Europe with these apps?
Yes. Trainline and Omio cover hundreds of train and bus operators across Europe, not just Spain, which makes them ideal for planning an Interrail trip or a journey through several countries. Renfe's official app, by contrast, only handles Renfe trains within Spain.
