1 Scope This European Standard specifies the minimum requirements for measuring principles and systems in order to produce comparable results. It applies to all measuring equipment fitted on dedicated recording vehicles, or on vehicles specifically modified for the same purpose, after the coming into force of the standard. It also defines the requirements of measurement. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13848-1, Railway applications – Track – Track geometry quality – Part 1: Characterisation of track geometry Other informative references concerning the environmental conditions (refer to 5.2) are provided in the Bibliography.
3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 track recording vehicle self propelled or hauled vehicle with fixed, dedicated, measuring equipment and systems, used for the measurement, assessment and recording of track geometry parameters under loaded conditions, which measures and produces consistent results, to the requirements of EN 13848-1 3.2 sensor device which detects, measures and translates characteristics of track geometry into quantities that can be used for further data processing 3.3 repeatability degree of agreement between the values of successive measurements of the same parameter made under the same conditions (speed, direction of measurement), where the individual measurements are carried out on the same section of track subject to the following controls:  same measurement method;  same vehicle orientation;  same method of interpretation;  similar environmental conditions;  short period of time between successive runs.

validation set of tests for determining if a track recording vehicle complies with the requirements of this standard 3.7 calibration set of procedures for adjusting the measuring devices of track recording vehicles in order to meet the requirements of this standard 3.8 event record of a track or line-side feature that can be either technical, physical or natural 3.9 localisation information required to locate events and the measured track geometry 3.10 reference track track with known characteristics necessary to allow adequate testing of the track geometry recording system 4 Symbols and abbreviations For the purposes of this European Standard, the following symbols and abbreviations apply.

5 Track recording vehicle 5.1 General description For the purpose of this standard, the track geometry recording system of the vehicle is divided into several units as represented in Figure 1 below:
Figure 1 — Track geometry recording system MEASURING SYSTEM / DEVICE (5.5) DATA OUTPUT (5.7) DATA STORAGE (5.8) TRACK FEATURES INPUT (5.3) DATA LOCALISATION (5.4) DATA PROCESSING (5.6)

An increase in the number of input signals as well as of the number of calculations made shall be foreseen in the system design. 5.6.2 Parameter generation The signals processed in 5.5.3 shall be calculated in order to obtain parameters complying with requirements of EN 13848-1.
