How to modify my ticket

Electronic tickets can be modified by us only if modification request is submitted no later than three business days before departure. Passed this deadline, ticket modification is not guaranteed.
If you need to modify your tickets after the deadline, you will need to book new tickets and to return the old tickets at the train station to claim a refund. If you are requesting to change your tickets before the deadline, but new tickets are not available, we will hold the original tickets until further instructions from you.
