Tickets are sold on the official Srbija Voz site. The form is in Serbian only, so every field is explained here — step by step.

Children
Children under 6 travel free and do not count as passengers, provided they do not take a seat. If the child has their own seat, the ticket costs the same as for children up to 14.
Payment
The form shows Visa, Mastercard, Maestro, American Express and DinaCard.
