UIC OR 450-2-2009 Assessment of the performance of the network related to rail traffic operation for the purpose of quality analyses - delay coding and dilay cause attribution process
This Leaflet is intended to ensure that Infrastructure Managers, Railway Undertakings and other organisations involved in quality analysis of international railway traffic are in possession of uniform data on the reliability of international passenger and freight trains, thus enabling them to analyse and steer punctuality on all the services.
With this in view, the Leaflet establishes a common coding system for identifying the causes of delays and not provided services. Furthermore it specifies unified methods and concepts intended for recording, transmitting and analysing the necessary data.
