Annotation

This IRS classifies lines for the purpose of track maintenance.
Traffic loads are one of the key factors that have a direct bearing on track maintenance.
In order to facilitate economic studies and comparisons between the different infrastructure managers (IM), lines are classified into several groups depending on the type of traffic and on the loads they carry.
For this purpose, a notional traffic value should be used, allowing for the speed factor and the relative wear effect of axle-loads. The method used for calculating the notional traffic value for tracks over a particular line section and the classification adopted are specified below.
