5 Geometry
The infrastructure manager shall ensure that the values for the geometric characteristics of the overhead
contact line are as shown in Table 2 and Table 3.
The pantographs of the train shall fulfil the geometric characteristics as shown in Table 4, according to
the type of infrastructure on which it will circulate under the rules of free access.
5.1 Overhead contact line characteristics
For free access the parametric requirements to achieve interaction that are dependent on the geometry of
the overhead contact line (see EN 50119) are as follows:
• contact wire height;
• gauge;
• permissible contact wire gradient;
• permissible lateral deflection of the contact wire under action of cross wind;
• contact wire uplift at the support;
• neutral section.
According to the Directive 96/48/EC, newly built European high-speed lines shall allow the circulation of
vehicles complying with GC as defined in UIC leaflet 506. For line speed AC 4 the contact wire height
shall not exceed a certain limit for aerodynamic reasons, which excludes gauges higher than GC (as for
piggyback services). The requirements for the contact wire uplift at the support are defined in
EN 50119:2001, subclause 5.2.1.3. The permissible contact wire gradient is also defined in
EN 50119:2001, subclause 5.2.8.2. The wind speed to be considered will be defined by the infrastructure
manager.
The functional requirements of neutral sections are defined as follows:
• trains shall be able to move from one section to an adjacent one (which is fed from a different phase
or system) without bridging the neutral section;
• the neutral section shall be designed in such a way that trains with several pantographs at an overall
distance of maximum 400 m can cross with their pantographs up;
• power consumption of the train shall be brought to zero when entering the phase separation section.
See also EN 50388;
• the infrastructure manager shall provide adequate means to allow a train that stops underneath the
phase separation section to restart;
• in the case of trains with several pantographs, the pantographs shall be lowered for the entire length
of the neutral section if some of the above requirements cannot be met. Technical or operational
measures shall be taken to meet safety and availability requirements.
For compatibility between neutral sections and pantographs arrangement, see 5.2 and A.1.

m and/or curved track this value shall be adjusted in accordance with A.3.

The overhead contact line shall conform to EN 50119.
5.2 Pantograph characteristics
The geometry of the pantograph is characterised by the following major interaction parameters:
• geometric profile of pantograph head;
• range of working height;
• length of contact strips;
• maximum width;
• skew of pantograph head.
For a current collection without interruption, functional requirements are described in this clause. These
requirements are related to the geometric profile of the pantograph head and to the dynamic behaviour of
the vehicle (i.e. kinematics envelope) and ensure that at least one contact wire is always inside the
conducting range of pantograph head (including all tolerances).
The permissible value for the skew of pantograph head is 60 mm.
The maximum lateral deviation of the European pantograph head is specified in A.3.
Additional characteristics, related to the train, shall also be implemented as follows:
• automatic dropping device;

---------------------- Page: 11 ----------------------

- 11 - EN 50367:2006
• minimum and maximum spacing between two operating pantographs;
• an electrical connection between operating pantographs in a.c. systems shall not be used;
• lowering times under normal conditions. From the moment of initiation, the pantograph shall lower to
the minimum voltage insulating distance in less than 3 s. The pantograph shall lower to the housed
position in less than 10 s.
NOTE 1 The limits for maximum width are important for the correct operation of sectioning devices. The limits for distances
between operating pantographs are important for the correct operation of neutral sections. See A.1.
NOTE 2 For d.c. systems, when an electrical connection between operating pantographs exists, a device to interrupt this
connection should be provided.
The design of the pantograph shall ensure performance in accordance with Clause 7 for the speed range
and a contact wire height according to Table 2 and Table 3. The maximum value of working height shall
be 6,5 m.
For compatibility between pantographs arrangement and neutral sections, see A.1.

6 Material interfaces
The wear of contact wire and contact strips as well as the permissible current at the contact point depend
significantly on the materials of these two components. In order to achieve a satisfactory performance the
characteristics of contact wire and contact strips shall be in accordance with 6.1 and 6.2.
6.1 Contact wire
The contact wire shall comply with the requirements of EN 50149 and shall be used in accordance with
EN 50119.
Permissible materials of contact wire are copper and copper-alloy.
NOTE  If other materials are used it is recommended to furnish proof that the characteristics are equal to or better than the
characteristics of the permitted materials.

---------------------- Page: 12 ----------------------

EN 50367:2006 - 12 -
6.2 Contact strips
The contact strips shall comply with the requirements of EN 50206-1. The type of contact strip used shall
be in accordance with the following properties:
– current capacity;
– contact force;
– contact strip material.
The material of the contact strips shall be subject to acceptance by the infrastructure manager.
Recommended material for the contact strips is plain carbon, if necessary impregnated with added
material.
For the use of other materials it is necessary to furnish proof that the characteristics are equal to or better
than the characteristics of the recommended materials.
NOTE 1 Commonly used other materials for contact strips are
– copper-steel, copper alloy, copper,
– copper-clad carbon,
– sintered material.
The operation with different contact strip material on the infrastructure network (see Table C.1) shall be
based on an agreement between infrastructure manager and transport company.
NOTE 2 If mixed materials for contact strips in the networks are used, the wear of contact strips and/or contact wire could
increase. For the results of investigation see Table C.2.
The contact strips material shall conform to EN 50405.
Additional tests for d.c.-systems see A.4.
7 Interaction performance
The performance of the overhead contact line and pantograph interface shall be subject to the approval
by the infrastructure manager.
7.1 Current capacity
The current in the overhead contact line depends on speed, train weight, distance between trains, line
gradient, overhead contact line construction. The properties of pantograph and contact wire shall be such
that overheating does not occur.
The maximum current depends on the following parameters:
• number and material of contact wires;
• number and material of contact strips;
• actual contact forces at the contact point;
• train speed;
• environnemental conditions.
The current demand of the train shall comply with the working limits of the overhead contact line. See
EN 50388,Table 2.
The static contact force should be adjustable for safe current collection at standstill.

A static contact force at standstill of 70 N for a.c. systems and 90 N for d.c. systems 1,5 kV
− 10 N − 20 N

and 110 N for 3 kV shall be used.
− 20 N
For some d.c. systems it may be necessary to use a static contact force around 140 N to improve the
contact of carbon collector strips with the contact wire to avoid a hazardous heating of the contact wire
when the train is at standstill with its auxiliaries working.
The maximum current at standstill is given in Table 5.

 1,5 kV 3 kV
Maximum current at standstill 80 300 200
per pantograph (A)

7.2 Interaction dynamic performance
Safety and performance of train operation, wear of the contact strips and contact wire are influenced by
the dynamic interaction between the pantograph and the overhead contact line.
The dynamic behaviour depends on the characteristics of the pantograph and overhead contact line and
the operating conditions. The principal operating conditions to be considered are the train speed, the
number, the distance and the position of the pantographs.
The acceptable number of pantographs and their minimum spacing are limited by the dynamic
performance of pantograph and overhead contact line.
For the safe operation of the system the necessary space for contact wire uplift at the support is required
in accordance with EN 50119, Subclause 5.2.1.2.
Good quality dynamic interaction performance with minimum wear is assured by consideration of quality
of current collection. This can be evaluated by
– F ; σ,
m
– percentage of arcing (NQ).
The infrastructure manager shall decide which measurement system will be used. The acceptance criteria
are considered to be met, if F ; σ or percentage of arcing and uplift at the support is fulfilled.
m
The values shall be measured in accordance with EN 50317.
For the qualification of the performance with more than one pantograph, the pantograph which shows the
most critical values shall be considered. The worst performing pantograph should be determined by
simulation in accordance with EN 50318 or testing in accordance with EN 50317.
In Table 6 values for interaction performance are shown. These values shall be respected for any
pantograph also in case of trains with multiple pantographs simultaneously in operation.
