Division 2.2.1 Interoperability

This TSI defines the functions, interfaces and performance requirements to ensure the achievement of technical interoperability. Technical interoperability is the prerequisite for operational interoperability, in which the driving is based on consistent information displayed in the cabs and is in accordance with unified operational requirements defined for the trans-European high speed network. This TSI also contains functions that are needed to achieve operational interoperability (see section 4.3.1 Interface to the Subsystem Traffic Operation and Management).
