EN 13232-8:2007 (E) 5 Introduction An expansion device is a device which permit longitudinal relative rail movement of two adjacent rails, while maintaining correct guidance and support. These longitudinal movements may be required in: a) interrupted CWR (continuously welded rail); b) structure movement; c) or a combination of both.



EN 13232-8:2007 (E) 6 1 Scope This part of EN 13232 covers the following subjects: to establish a working terminology for expansion devices, for their constituent parts and for the types; to specify the minimum manufacturing requirements for expansion devices and their constituent parts; to formulate codes of practice for inspection and tolerances; to define the method by which expansion devices and their parts should be identified and traced. 2 Normative references The following referenced documents are indispensable for the application of this document.

With check rails, there may be two LH or two RH half sets, see Figure 6, or opposite hand half sets 3.1.2 hand (of half set) – expansion switch LH half set or a RH half set when viewed standing in the track gauge and facing the toes of the expansion switch 3.1.3 expansion capacity C maximum permissible relative longitudinal movement between the two rails, where: C = Dmax – Dmin

EN 13232-8:2007 (E) 13  train speed;  nominal track gauge;  direction of traffic;  track geometry. In addition the customer shall decide:  the type of expansion device to be applied;  the expansion capacity of the expansion device as well as the maximum displacement rail/support. If the latter is not provided, it shall be estimated to be half the expansion capacity of the device;  the basic rail section and grade;  the rail inclination to be applied through the expansion device;  the fastening system to be applied;  the nominal support spacing;  type of support structure, e.g. bearer, slab track;  special requirements, e.g. limits of vertical and horizontal end rotations, limits of local vertical and horizontal radii of track, limits of uplift movements on rail supports adjacent to the gap between the structure and the abutment or between the structures. The following elements shall be agreed between customer and supplier:  the special rail profiles to be applied for the construction (if applicable);  the constructional length;  the machining details of the rail sections;  the maximum support spacing in service. 4.2 Design rules 4.2.1 General rules 4.2.1.1 Support panel In the case where 1 side is moveable, a number of bearers shall be restrained from moving. This is normally a minimum of four bearers. The incoming rails shall have low resistance fastenings on the restrained bearers to permit movement of the moveable rails. All restrained bearers are linked to each other. This can be achieved by the use of a bearer strap, guard rail, continuous base plate etc. In the case when both sides are moveable, the bearers shall be restrained from moving by means of a steel strap. This is to ensure bearer distance does not change and prohibits the bearers from moving from their nominal position during operation and/or maintenance.



EN 13232-8:2007 (E) 14 4.2.1.2 Low restraint fastenings The fastening restraint shall in any case be smaller than the longitudinal restraint of the bearer in the ballast. The creep resistance shall be between 0 and 5 kN per base plate. This resistance shall be checked in accordance with EN 13146-1. 4.2.1.3 Slide chairs The slide chair shall permit the movement of one or both rails, while offering guidance to the switch and/or stock rail depending on the type used, with resistance in the range 0 to 5 kN. The resistance shall be checked in accordance with EN 13146-1. 4.2.1.4 Total longitudinal r
