is the UK implementation of EN 16432-1:2017 BSI, as a member of CEN, is obliged to publish 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 practitioners within the UK The area for clarification is Section Railway Tra ffic Loading Users are advised that: • Load model 71 alone may not represent the most onerous case for a specific project and designers should seek to identi fy all relevant load models for application • Attention is drawn to the need to determine the worst-case combination of vertical, lateral and longitudinal loads • No information is provided concerning fatigue analysis and its application • Clause 5.1.2.2 omits to mention that load model 71 excludes representation o f passenger trains at speeds >200 km/h • The formula stated in Clause 5.1.3.2 equates to the use in other Standards o f Nosing Loads combined with centri fugal e ffects • Users are directed to SPARK in T1073 Phase Summary Report for further detailed information concerning loading The UK participation in its preparation was entrusted to Technical Committee RAE/2, Railway Applications - Track Membership o f the subcommittee Ballastless

applications up to 250 kN axle load The requirements of this standard apply to: — plain line track, switches and crossings and rail expansion joints; — various substructures like embankments and cuttings, tunnels, bridges or similar, with or without floating slabs; — transitions between different substructures; — transitions between different ballastless track systems; — transitions between ballasted and ballastless track systems NOTE Requirements for characterization of the substructures listed above are included in this standard Design of the substructures is covered by other European

rolling stock Terms and definitions For the purposes of this document, the following terms and definitions apply 3.1 design life assumed period for which a ballastless track system, or part of it, is to be used for its intended purpose with planned maintenance but without major repair 3.2 Electromagnetic Compatibility EMC ability of equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment 3.3 floating slab track system where a designed elasticity is introduced between the ballastless track system and substructure EXAMPLE For vibration mitigation 3.4 substructure earthworks (embankment, cutting or at-grade) or bridges (or similar civil structures) or tunnel floor that lie below the ballastless track system 3.5 static action action that does not cause significant acceleration of the structure or structural members 3.6 quasi-static action dynamic action represented by an equivalent static action in a static model 3.7 dynamic action action that causes significant acceleration of the structure or structural members 3.8 exceptional load infrequent load which exceeds the limit for the relevant operational conditions 3.9 track stability resistance of the track to buckling BS EN 16432-1:2017 EN 16432-1:2017 (E) A.2.2 Heating of the rail It is considered that all the force of braking of the eddy current brake is dissipated in heat in the rail such as: (A.1) F = C ì ì T where F is the braking force (by length of rail) in kN; µ is the mass of the rail per unit of length in kg m -1 ; C is the heat capacity of rail steel in kJ × kg-1 K-1 the value used is C = 0,460 kJ × kg-1 K-1 ; δT is the heating variation of the rail in K For the rail 60E1 the characteristic value is δT/F = 0,0360 K/kN A.2.3 Cooling of the rail For the rule of cooling of the rail the following equation applies: δT = δ n Tn − × − t /τ (A.2) where δT is the initial heating of the rail in K; τ is the reference time, e.g 476 in s for rail profile 60 kg/m; t is the time between two trains in s; n is the number of trains that have passed n −1 A.2.4 Example of calculation Hypothesis: F= 180 kN the braking force (by length of rail) in kN; t= 620 s (27 min) Rail 60E1 τ time between two trains in s δT /F = 0,0360 K/kN 476 s reference time for rail profile 60 kg/m Calculation: Just after the 1st train, δT = δT = 0, 0363 × F = 6, 48 K After 27 (1 620s) and just after the 2nd train, δT ( = δT + δT )×2 − t /τ = 10, 60 K ( δ T2 = 6, 48 + 6, 48 × −1620 / 2476 ) After 27 (1 620 s) and just after the 3rd train, δT ( = δT + δT )×2 − t /τ = 13, 21 K ( δ T3 = 6, 48 + 10, 60 × −1620 / 2476 ) 21 BS EN 16432-1:2017 EN 16432-1:2017 (E) After 27 (1 620 s) and just after the 4th train, δT ( = δT + δT )×2 − t /τ = 14, 88 K ( δ T4 = 6, 48 + 13, 21 × −1620 / 2476 ) etc After 27 (1 620 s) and just after the 18th train, δT 18 22 ( = δT + δT 17 )×2 − t /τ = 17, 77 K ( δ T18 = 6, 48 + 17, 76 × −1620 / 2476 ) BS EN 16432-1:2017 EN 16432-1:2017 (E) Annex B (informative) Examples of loop-free and zones with limited metal content to ensure EMC B.1 Track circuit bond The
