Electronic reservation of seats/berths and electronic production of travel documents - Exchange of messages

IRS 90918-1 describes the regulations and procedures to be observed when exchanging messages between a RU that issues travel tickets and reservation tickets and the electronic system of the RU which manages the necessary data for the issue of these tickets, in particular the inventories of seats available for reservation. It is supplemented by the following two leaflets/IRS:

• IRS 90918-0 which deals with the general arrangements for electronic seat reservation and the electronic preparation of travel documents;
• UIC Leaflet 918-2 which describes the standard RCT2 that applies to all the travel documents prepared electronically (the only people allowed access to this IRS are the correspondents whose names are on the list held by the UIC Passenger Department);
• ERA TAP TSI Technical Document B.6 which describes the standard RCT2 that applies to all the travel documents prepared electronically;
• ERA TAP TSI Technical Document B.7 which describes the standard for home-printed tickets to be used in international carriage by train.

The arrangements contained in these IRS enable a RU to reserve seats from an inventory managed by another RU and to issue any travel document (in particular seatreservations and combined tickets) produced electronically from data transmitted by the electronic system of another RU.

Note: the term "seat" in this IRS is used to identify the group of services e.g. berth, bicycle, seats, etc. but can also be used to address a seat.
