This document specifies the minimum requirements to meet by measuring systems fitted on track geometry measuring trolleys and manually operated devices to give an evaluation of track geometry quality when using one or more of the parameters described in EN 13848 1. It sets out the acceptable differences from EN 13848 1 when using track geometry measuring trolleys and manually operated devices to measure track geometry.
It applies to all track geometry measuring systems fitted to track geometry measuring trolleys and manually operated devices after the date of implementation of this document.
In the case of lightweight devices working at a speed higher than walking speed, or in the case of track geometry measuring systems installed on track recording cars but not measuring in loaded conditions as defined in EN 13848 1, the test procedure defined in EN 13848 2 is applicable.
