The Customer shall provide the following parameter values:  wheel back-to-back (see Figure 1);  axle spacing;  number of axles;  clearance of middle axles, if applicable;  bogie spacing and minimum curve radius for vehicles. 3.5 Rail and track The key parameters related to the track geometry which are used in calculations for wheelset guidance are shown in Figure 2 and listed below:  centreline radius (R);  track gauge (G);  dimension for nose protection (check gauge) (F);  wing flangeway (D).

Key 1 Highside 2 Wing 3 Check 4 Lowside Figure 2 — Key track dimensions and the following shall be provided by the Customer:  maximum permissible check rail height above running table (H). 3.6 Tolerances and wear It is necessary to consider tolerances and wear in order to design correctly. These are alternatively referred to as manufacturing tolerances and service tolerances. If the Customer provides worn wheel profiles or amounts of wear, then these should be used. Otherwise the assumptions made by the Supplier shall form the basis for design, and these shall be stated. Examples of key areas of wear are:  back of wheel flanges;  front of wheel flanges;  false flanges;  flange angle. Locations of typical lateral wheel and track wear are shown in Figure 3. These must be taken into account when designing flangeway gaps. See clause 4. SIST EN 13232-3:2004+A1:2012

See clause 5. False flanges are to be avoided as they will increase wear as well as the rate of damage to switches and crossings. 3.7 Contact zone For switch and crossing design, there are issues which shall be verified during design. These are as follows. 3.7.1 Contact profile The relative radii of wheel and rail shall be taken into account. 3.7.2 Contact danger zone The wheel profile supplied by the Customer shall indicate the danger zone for guidance contact, which is that part
