Either on the website or at an international ticket office in Russia.
Ticket returns abroad are subject to the production of a paper ticket previously obtained in the Russian Federation. That said, only seat returns are possible; refund policy is as follows:
If a ticket was issued for travel to the CIS countries and the Baltic states or Abkhazia, you must go to a ticket office in Russia within six months of the train departure date and produce:
- seat return form;
- your unused ticket;
- the passenger’s identity document.
If a ticket was issued for travel to non-CIS countries, you must go to an international ticket office in Russia within one month of the train departure date and submit:
- your ticket marked as unused (specifying the passenger’s inquiry date and time);
- a refund application.
