No, it is not possible. Once the official departure time has passed, your ticket automatically loses its validity and cannot be exchanged or cancelled.

If you need to continue your journey, you will need to purchase a new ticket for the next available time. You can check upcoming departures and book your seat instantly via our Alsa App, the website, or at the station's ticket machines and offices.
