Railway applications. Track. Track geometry quality - Measuring systems. Manual and lightweight devices1 Scope This part of this European Standard specifies the minimum requirements that shall be met by measuring systems fitted on track geometry measuring trolleys and manually operated devices to give an evaluation of track geometry quality when measuring one or more of the parameters described in EN 138481: 2003+A1: 2008. It sets out the acceptable differences from EN 138481: 2003+A1: 2008 when using track geometry measuring trolleys and manually
