If you book a train that requires mandatory seat reservations, the point-to-point ticket price already includes the reservation fee. Seats will be automatically assigned by the system during booking, but passengers cannot choose their seats manually.  

Reminder:  

• If two or more people are traveling together, please make sure to book all tickets in a single order with the correct number of passengers. This gives the system a chance to assign seats together (subject to availability).  
• If tickets are booked separately or added later, the system may assign seats in different cars or locations, and sitting together cannot be guaranteed.
