PD CEN/TR 16513:2014CEN/TR 16513:2014 (E) 4 1 Scope CEN/TC 256/SC 1/WG 28 “Railway applications/Infrastructure/Track geometry quality“ conducted a survey of the geometric quality of track across European railw
13、ay networks. This was to get an understanding and overview of the track geometry across Europe in order to support the definition of track geometric quality classes for the writing of EN 13848-6. This Technical Report describes the methodology used for the survey and gives the results. 2 Terms and d
14、efinitions For the purposes of this document, the following terms and definitions apply. 2.1 track quality index TQI value that characterises track geometry quality of a track section based on parameters and measuring methods compliant with the EN 13848 series 2.2 track quality class TQC characteris
15、ation of track geometry quality as a function of speed and expressed as a range of TQIs 2.3 re-colouring algorithm which converts one signal into a different signal and which is used in the EN 13848 series to convert a chord measurement signal into a D1 or D2 measurement signal 3 Symbols and abbrevi
16、ations For the purposes of this document, the following symbols and abbreviations apply. Table 1 Symbols and abbreviations Symbol Designation Unit AL Alignment mm D1 Wavelength range 3 m 230 km/h). This can be observed for both longitudinal level and alignment. For a given speed class, this spread i
17、s also wider for longitudinal level than for alignment. When comparing the survey results with QN1 and QN2 levels, it was found that: for most speed classes, QN1 and QN2 do not match the 50 % and 90 % values of the corresponding distributions for both alignment and longitudinal level (see Figures 1
18、and 3); for all speed classes up to 230 km/h, QN2 is lower than the 90 % values of the SDLLdistribution, however they are within 20 % except for lines up to and including 80 km/h (see Figure 1); for all speed classes, the 50 % values of the SDLLdistribution are better than QN1 levels (see Figure 1);
19、 for all speed classes above 80 km/h, the 50 % values of the SDALdistribution are better than QN1 levels (see Figure 3), it is not practical to have a realistic track quality distribution that fits both QN1 and QN2. This is due to the closeness of their values. Positioning QN1 and QN2 on the cumulat
20、ive frequency distributions for all speed ranges leads to results presented in Table 3.

21、ion of the results to EN 13848-6 The definition of the TQCs in EN 13848-6 is based on the cumulative distribution of the weighted average of all the networks participating in the European track quality survey. The five TQCs are defined as follows: Class A below 10 % of the distribution corresponding
22、 to the best 10 %; Class B between 10 % and 30 % of the distribution; Class C between 30 % and 70 % of the distribution; Class D between 70 % and 90 % of the distribution; Class E above 90 % of the distribution corresponding to the worst 10 %.
