21、pean Standard (EN 13232-7:2006) has been prepared by Technical Committee CEN/TC 256 “Railway applications”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by
22、 September 2006, and conflicting national standards shall be withdrawn at the latest by September 2006. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association to support Essential Requirements of EU Directive 96/48/EC
23、of 23 July 1996 on the interoperability of the trans-European high-speed rail system amended by the Directive 2004/50/EC of the European Parliament and of the Council of 29 April 2004. For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standar
24、d. This series of standards “Railway applications Track Switches and crossings” covers the design and quality of switches and crossings in flat bottom rails. The list of parts is as follows: Part 1 : Definitions Part 2 : Requirements for geometric design Part 3 : Requirements for wheel/rail interact
25、ion Part 4 : Actuation, locking and detection Part 5 : Switches Part 6 : Fixed common and obtuse crossings Part 7 : Crossings with moveable parts Part 8 : Expansion devices Part 9 : Layouts Part 1 contains terminology used throughout all parts of the standard. Parts 2 to 4 contain basic design guide
26、s and are applicable to all switch and crossing assemblies. Parts 5 to 8 deal with particular types of equipment, including their tolerances. These use parts 1 to 4 as a basis. Part 9 defines the functional and geometrical dimensions and tolerances for layout assembly. The following terms are used w

30、, Uncontrolled Copy, (c) BSIEN 13232-7:2006 (E) 6 Introduction The requirements of crossings with moveable parts are that they are capable of performing their intended purpose, which is to allow a vehicle to pass the area where the two rails cross with a continuous running edge. That means the wheel
31、s of the vehicle are fully supported and guided in the whole crossing area, either in the facing or trailing direction. The main criteria for the selection of crossings with moveable parts are: improvement of ride comfort; reduction of noise and vibration; reduction of maintenance; mixed traffic con
32、ditions (e.g. train/tram); security against derailment. This last point is particularly important (critical) in diamond crossings. Effectively, as the wheel diameter and the obtuse crossing angle decrease, the distance without guidance (EN 13232-3:2003, 4.2.5) increases. Therefore, to assure the saf
33、ety of running of the wheel set over the diamond crossing, it is sometimes necessary to design the obtuse crossing as moveable. Rules and recommendations for security against derailment in diamond crossings are set down in part 9 of this standard. The crossings with moveable parts shall be designed
34、to withstand all external forces from rolling stock, thermal influences etc. The customer shall specify the maximum strains or stresses due to external thermal forces that the crossing with moveable parts has to withstand. Operating, signalling systems, heater systems, load bearing supports, maintai
35、nability and safety are all major factors which should be taken into account during the design. The performance criteria shall be based on information given by the customer. The design and selection of types of crossings with moveable parts will be influenced by axle loads, frequency of traffic and
36、speed.

37、nd their constituent parts, and identify the main types; to list the minimum informative requirements for the manufacture of crossings with moveable parts and/or their constituent parts; to formulate codes of practice for inspection and tolerances for crossings with moveable parts and/or their const
38、ituent parts; to establish the limits and extent of supply; to list the method by which crossings with moveable parts and their constructional parts should be identified and traced; to list the different and varying ways by which crossings with moveable parts can be described, using the following pa
39、rameters: geometry of crossings; types of construction; performance requirements; design criteria; tolerances and inspection. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

45、veable parts There are two major types of common crossing with moveable parts. These are crossing with moveable point (see Figure 1) and crossing with moveable wing rails (see Figure 2). In both cases: The wings and vee support can be: saddle (cast, welded, machined); assembled (made of different ra
46、il profiles, e.g. standard rail, asymmetric low section, symmetric thick web section etc.). The vee can be: monobloc (cast, welded, machined); assembled (made of different rail profiles, e.g. standard rail, asymmetric low section, symmetric thick web section etc.). Rail profiles shall be according t
47、o EN 13674-1 and EN 13674-2. In the case of a crossing with moveable point: point may or may not contain a longitudinal sliding area; vee of point and splice rail may be coupled by bolting, welding or fabricated out of a monobloc and welded to their respective adjacent legs. For example see Figures
48、3, 4 and 5. In the case of a crossing with moveable wing rails a longitudinal sliding area is not required. Other types of construction and their requirements shall be agreed between customer and supplier. 3.2 Obtuse crossings with moveable parts The main type of obtuse crossing with moveable parts
49、is the switch diamond crossing (see Figure 6).
