Disruption

When some disorder on the rail network leads to disruption of the rail services provided by IMs to RUs, and consequently to train services provided by RUs to their customers. It is an unplanned, uncontrolled event disrupting train operations on the network that requires operative treatment of trains. The term in Handbook is not linked to Eurostat/ITF/UNECE definition: "Extensive disruption to traffic" occurs when train services on at least one main railway line are suspended for more than six hours.
