BSI, as a member of CEN, is obliged to publ

2、ish EN 16432-1:2017 as a British Standard.Attention is drawn to the fact that during the development of this European Standard, the UK committee identified issues relevant to the UK implementation of the Standard.It is the view of the UK committee that further clarity is necessary for designers and

3、practitioners within the UK. The area for clarification is Section 5 Railway Traffic Loading.Users are advised that: Load model 71 alone may not represent the most onerous case for aspecific project and designers should seek to identify all relevant loadmodels for application. Attention is drawn to

4、the need to determine the worst-casecombination of vertical, lateral and longitudinal loads. No information is provided concerning fatigue analysis and itsapplication. Clause 5.1.2.2 omits to mention that load model 71 excludesrepresentation of passenger trains at speeds 200 km/h. The formula stated

5、 in Clause 5.1.3.2 equates to the use in otherStandards of Nosing Loads combined with centrifugal effects. Users are directed to SPARK in T1073 Phase 1 Summary Report forfurther detailed information concerning loading.The UK participation in its preparation was entrusted to Technical Committee RAE/2

42、of this document, the following abbreviations apply. CWR Continuous Welded Rail EMC Electromagnetic Compatibility UV Ultra Violet (radiation) ECB Eddy Current Brake 5 External actions 5.1 Railway traffic loading 5.1.1 General The main function of the track is to safely guide the vehicle and to distr

43、ibute the loads through the ballastless track system to the substructure. The ballastless track system shall carry the loads from the railway traffic over the design life within the specified operational and safety limits. Loads are generated by: static or quasi static actions; dynamic actions; exce

44、ptional actions. Other loads associated with construction, maintenance and emergency access shall be considered as necessary. 5.1 of this standard describes the requirements of railway traffic by vehicles that run on the rails of the ballastless track system. NOTE Other vehicles that run during cons

45、truction, maintenance or during an emergency or at level crossings on the track surface beside the rails are not in the scope of this standard. 5.1.2 Vertical loads 5.1.2.1 General If no specific information is available regarding the vertical loading then load model 71 shall be applied as static ve

46、rtical load for railway traffic to design the rail supporting structure. If specified, the ballastless track system may also be designed for vertical loads which are of short duration or are applied only infrequently during the design life according to the line category. Also models representing rea

47、l vehicles may be used. 5.1.2.2 Load model 71 The rail traffic covered by load model 71 according to EN 1991-2:2003, 6.3.2, represents all types of vehicles and European standard railway traffic up to 250 kN axle load. 5.1.2.3 Load model according to line category If specified by the customer, verti

48、cal load models according to the line categories in EN 15528 shall be applied for the design of the ballastless track system. BS EN 16432-1:2017EN 16432-1:2017 (E) 9 5.1.2.4 Real vehicle model If specified by the customer, a real vehicle load model representing the conditions of traffic operation fo

49、r the line (e.g. for specially dedicated rolling stock running on self-contained railways with uniform traffic and limited variation in vehicle type over the design life) shall be used for the design of the ballastless track system. 5.1.2.5 Additional vertical loads Vertical static loads act unequally on the inner and outer rails due to centrifugal effects in curves or non-uniform load distribution. Such effects shall be determined on the basis of the applied vehicle model, taking into account of track alignment parameters such as cant and cant d
