Hi, a train reservation consists of two different fees - a train reservation fee and a booking fee. 

• The train reservation fee: prices are per traveller and vary depending on the train. See the full list of train reservation fees.
• The booking fee: when you book through our Self-Service this is 2 euros per traveller, per train.
• For reservations that are only offered as a physical (paper) ticket there is also a shipping fee. This fee is €9 per order (registered mail).

Example: These are the costs for a 1st class reservation for 2 travellers on the Thalys high-speed train from Paris to Amsterdam: 2x € 2 booking fee + 2 x € 35 train reservation fee.
