prEN 13232-7:2014 (E)
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 wheels 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 conditions (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 safety 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 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, maintainability 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 speed.
prEN 13232-7:2014 (E)
1 Scope
The scope of this part is:
to establish a working terminology for crossings with moveable parts, which means crossings with
moveable parts to close the gap of the running edge, and 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
constituent 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 parameters:
geometry of crossings;
types of construction;
performance requirements;
design criteria;
tolerances and inspection.

3 Types of crossing with moveable parts
3.1 Common crossings with moveable 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 rail 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 to 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 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 is the switch diamond crossing (see Figure 6).
The wing and switches rails support can be:
saddle (cast, welded, machined);
assembled (made of different rail profiles, e.g. standard rail, asymmetric low section, symmetric thick web
section etc.).
The wing rail can be:
prEN 13232-7:2014 (E)
monobloc (cast, welded, machined);
assembled (made of different rail profiles, e.g. standard rail, asymmetric low section, symmetric thick web
section etc.).
Switch diamond crossings can be used in obtuse crossings with or without single or double slips.
Rail profiles shall be according to EN 13674-1 and EN 13674-2.
3.3 Materials
The materials used shall be defined at least by their respective European Standard or by their mechanical and
chemical characteristics in the non-existence of a European Standard.
The grade and specification of rails to be used shall be specified by the customer and shall comply with
EN 13674 (all parts). All bolts and other fixing devices shall be minimum grade 5.6. All other blocks and fittings
shall be manufactured to minimum grade 200. The use of other materials shall be agreed between customer
and supplier.
3.4 Geometry
The geometry of the crossing at the running edges (straight or curved) shall be in accordance with the general
layout according to prEN 13232-2:2014 and prEN 13232-9:2014.
3.5 Inclination of the running table
The running table of the crossing may or may not be inclined.
Inclination of any running table in the crossing and location and length of any twist (change of inclination) shall
be defined.
3.6 Construction
If a transition from special rail profile to standard rail profile is required, the transition can either be located in
the fixed part or in the moveable part. In case of a weld, in the moveable part, the weld shall be secured by
fishplating.
3.7 Relationship with the adjacent track
The crossing can be joined to the adjacent track:
by fishplates;
by glued fishplates;
by welding.
