UIC Leaflet918-1 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:
UIC Leaflet 918-0 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 Leaflet are the correspondents
whose names are on the list held by the UIC Passenger Department)
The arrangements contained in these Leaflets enable a RU to reserve seats from an inventory
managed by another RU and to issue any travel document (in particular seat reservations and
combined tickets) produced electronically from data transmitted by the electronic system of another
RU.
Note: the term "seat" in this leaflet is to identify the group of services e.g. berth, bicycle, seats, etc
but can also be used to address a seat.
