TAF TAP TSI
The TAF/TAP TSI (Technical Specification for Interoperability relating to Telematics Applications for Freight/Passenger Services) aim to define the data exchange between individual Infrastructure Managers (IMs) and also between IMs and Railway Undertakings (RUs).
In addition to data exchange, the TAF TSI describes business processes involving IMs and RUs. For this reason the TAF TSI deeply impacts existing international rail infrastructure business processes. The TAF, or at least the IT interfaces with other partners, must be implemented in a similar way by all TAF TSI partners, including the IMs. More information is available on the TAF TSI joint Sector Group webpage.
The TAF TSI functions define data processing regarding the following variables:
- When (at which point in time)
- What (which kind of information and content) has to be sent to
- Whom (partner or partners) and
- How (in which format) the data must be exchanged.
A mandate to coordinate the IMs within the TAF/TAP TSI framework was given to RNE by its General Assembly in May 2008 and renewed in May 2012. Since that time, RNE has provided strong support by coordinating and organising the implementation of the TAF & TAP.
TAF TSI Timeline
TAF TSI Master Plan and Implementation
Today the RNE systems, CCS, TIS and PCS, are already compliant with TAF and TAP TSIs; they are even viewed as front-runner systems for TAF and TAP. RNE has taken over the TAF TSI Common Components in January 2015. Therefore RNE is coordinating the rollout of the Common Interface and the publication of the Reference Files including the primary location code. In RNE’s TIS application, the TAF standard has been in use in the production environment for every new data exchange since summer 2013. PCS is used as the key system for the TAF TSI Short Term Path request pilot. Thus, the Rail Sector is already exchanging several million messages within the TAF/TAP TSI framework every month.
RNE would like to thank the European Commission (INEA) for its financial contribution to projects carried out by RNE and its Members, the most recent ones being ‘Study on the implementation and establishment of Rail Freight Corridors including pilot interventions and telematics applications for TSI implementation’ (2012-EU-94031-S), which ended in December 2015, and the follow-up project ‘Coordinated and harmonised implementation of the rail freight corridors and the telematics applications for freight and passengers’ which ends in December 2017.
