Exchange of data concerning the running of international passenger and freight trains between Infrastructure Managers for the purpose of quality analysis
Every Infrastructure Managers (IM) (see List of abbreviations - page 26) bears a heavy responsibility
for the reliability of the train movements on his network.
Punctuality is one of the vital factors in the quality of train service.
The purpose of this Leaflet is therefore to enable the IM and any other bodies involved in international
traffic to acquire uniform data on the reliability of international passenger and freight train movements.
The data is collected using uniform methods and definitions.
On the basis of the data provided, it should be possible to identify weak points and then to take the
organisational steps or apply the technical measures necessary, or else to arrange rescheduling.
The Leaflet allows for the collection, preparation and transmission of data either manually or by
computer. The standardisation of the data and the rules governing its electronic transmission and
processing are covered by UIC Leaflet 407-1 (see Bibliography - page 27).
The contents of the Leaflet are binding on all IMs involved in the execution of international quality
analysis. Those areas which are merely recommended are expressly indicated as such in the text.
