This Technical Specification provides in Clause 2 new and changed Glossary items needed to define Indirect Fulfilment and its characteristics and to support the changes to the TAP-TSI and Technical Document B5. It defines in Clause 3 the layout formats used for international rail services fulfilled using the ticket-on-departure and print-at-home ticket methods. Clause 4 provide the changes to Technical Document B5 that are required to provide the generic Indirect Fulfilment framework, covering ticket-on-departure, print-at-home and e-ticket fulfilment methods, although the main use of the specification is expected to be for ticket-on-departure. Clause 5 provides the analysis of the security requirements of Indirect Fulfilment, and the conclusion that no rail-specific specifications are needed.
