EN 13848-5:2008 (E) 4 1 Scope This European Standard defines the minimum requirements for the quality levels of track geometry, and specifies the safety related limits for each parameter as defined in EN 13848-1. This standard covers the following topics: description of quality levels; relative importance of parameters; immediate action limit; considerations on other quality levels. This European Standard applies to high-speed and conventional plain line of 1 435 mm and wider gauge railways provided that the vehicles operated on those lines comply with EN 14363 and other vehicle safety standards. For lines covered by the high speed infrastructure TSI, the requirements stated in the HS INS TSI prevail. Any track geometry parameter not covered by the HS INS TSI needs to be compliant with this European Standard. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 nominal track gauge reference value for track gauge used by individual networks 3.2 design track gauge design value of track gauge for a given track section, which might be different from the nominal track gauge 3.3 QN1 level refer to EN 14363 3.4 QN2 level refer to EN 14363 3.5 QN3 level refer to EN 14363 SIST EN 13848-5:2008

5 Background The importance of knowing the track geometric quality arose in the middle of 20th century, when European infrastructure managers developed their own track recording vehicles allowing a continuous measurement of track geometry and based on this, their own track geometry quality evaluation standards. These independent developments resulted in different measuring and evaluation methods which are no longer adequate in the light of the requirements of European railway interoperability. This is because it is difficult to compare the track geometry conditions of various European infrastructures. Yet, at least for safety reasons, it is necessary to make such comparisons. The main purpose of the standard is to define a minimum track geometry quality to ensure safe operation of trains based on the experience of various European infrastructure managers. 6 Overview This European Standard sets out quality levels, in particular immediate action limits, with the aim of harmonising European track geometry quality standards. It can be significant in: optimisation of track geometry maintenance works; optimisation of vehicle ride quality and dynamic loading of the track; SIST EN 13848-5:2008
EN 13848-5:2008 (E) 6 harmonising vehicle acceptance procedures. Requirements given in this European Standard should be taken into account: by infrastructure managers; by track maintenance managers; by vehicle manufacturers; by track contractors; by regulatory authorities; for research purposes. The values stated in this European Standard are based on the values prescribed by various European railways. Furthermore, this standard takes into account, as far as possible, the previous studies made on this topic: Annex C of EN 14363:2005; TSI for high-speed line infrastructure; ORE Question B55 report N.o 8 (1983). 7 Assessment of track geometric quality All the parameters as defined in EN 13848-1 are encompassed in this European Standard; their respective importance and their influence on vehicle behaviour are described in Annex A. Three indicators can describe the track geometric quality: extreme values of isolated defects; standard deviation over a defined length, typically 200 m; mean value. NOTE 1 Consideration should be given to successions of isolated defects because they could generate resonance effects, and to combinations of defects in several parameters at the same location (see Annex A). Three main levels have to be considered: Immediate Action Limit (IAL): refers to the value which, if exceeded, requires taking measures to reduce the risk of derailment to an acceptable level. This can be done either by closing the line, reducing speed or by correction of track geometry; Intervention Limit (IL): refers to the value which, if exceeded, requires corrective maintenance in order that the immediate action limit shall not be reached before the next inspection; Alert Limit (AL): refers to the value which, if exceeded, requires that the track geometry condition is analysed and considered in the regularly planned maintenance operations. SIST EN 13848-5:2008
EN 13848-5:2008 (E) 7 These values are given as a function of speed, which is an important factor for the evaluation of track geometry quality. Parts 2, 3 and 4 of EN 13848 give measuring methods for track geometry whereby track geometry quality can be assessed. The values in the tables are given for a loaded track as defined in EN 13848-1. When the measurements are made on unloaded track, the difference in the measured values that may result need to be taken into account. The normative part of the standard gives IALs for isolated defects and for mean track gauge. The informative part of this European Standard gives ILs and ALs for isolated defects and mean track gauge, and ALs for standard deviations. The track geometry limits AL, IL and IAL differ from the 3 vehicle acceptance levels QN1, QN2 and QN3 used in EN 14363. More particularly QN3 is quite different from IAL because, according to EN 14363, it characterises track sections which do not exhibit the usual track geometry quality. Quality level QN3, however, does not represent the most adverse but still tolerable maintenance status which still allows regular train operations. NOTE 2 A further quality level of track geometry can be used for track works acceptance (see EN 13231-1). NOTE 3 The intervention limit depends on the corrective maintenance policy, the frequency of inspection and defect growth rate. 8 Immediate action limits 8.1 Introductory remarks The immediate action limit values given in this standard are derived from experience and from theoretical considerations of the wheel-rail interaction as physical tests with different vehicles up to the point of derailment are not practicable. Exceeding these immediate action limit values requires specific measures to be implemented to reduce the risk of derailment or other hazards to an acceptable level. The wavelength range D3 is not taken into account in the following, as it is not directly linked with safety, but more with vehicle ride quality. The immediate action limits given in the following tables and figures are normative. With the exception of track gauge, all values stated are absolute. 8.2 Track gauge The values provided in the following tables apply to the nominal track gauges 1 435 mm, 1 524 mm and
1 668 mm. Networks using other nominal track gauges shall adjust the values accordingly. The reference for the track gauge in the HS INS TSI is 1 435 mm. NOTE The minimum and maximum values in Table 2 and Table 3 are independent from the design track gauge. SIST EN 13848-5:2008

The mean, in the table above, is calculated over a length of at least twice the higher wavelength in the D1 or D2 range. In practice the mean will be close to zero and therefore zero to peak values may be used. Special attention should be paid to short wavelength defects which, although unlikely, can become dangerous when their amplitude is high. NOTE For speeds less than or equal to 40 km/h, the limit can be relaxed to 31 mm. 8.4
