Raw data exchange between IMs based on the TAF/TAP TSI framework is already in place with large companies running international railway businesses such as Eurostar, SBB Cargo Int, DB Schenker Rail, BLS Cargo etc.. The filtered exchange of data makes the process more efficient and the user’s maintenance efforts could thus be reduced significantly.

The filtering function for selecting required information for the data exchange is based on:

• Company (IM, RU, Points…)
• Mutual/general agreements between companies involved in the train run
• Functional criteria (points, incoming trains, outgoing trains, delayed trains, etc.)
• TAF TSI reference system for testing of messages within the TAF/TAP TSI framework.
