TECHNICAL CRITERIA FOR THE INTERACTION
BETWEEN PANTOGRAPH AND OVERHEAD LINE
(TO ACHIEVE FREE ACCESS)
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

5 Geometry
5.1 General
The infrastructure manager shall ensure that the values for the geometric characteristics of
the overhead contact line are as shown in Table 1 and Table 2.
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.
5.2 Overhead contact line characteristics
For free access, the parametric requirements to achieve interaction that are dependent on the
geometry of the overhead contact line 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.
Newly built high-speed lines shall allow the circulation of vehicles complying with GC as
defined in UIC leaflet 506. For line speed more than 250 km/h, 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
---------------------- Page: 11 ----------------------
– 10 – 62486 © IEC:2010
defined in 5.2.1.3 of EN 50119:2001 in Europe. The permissible contact wire gradient is
defined in 5.2.8.2 of EN 50119:2001 in Europe. 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, except in case of changeover
section, when entering the phase separation section. See also IEC 62313;
– the infrastructure manager shall provide adequate means to allow a train that stops
underneath the neutral section to restart. See also IEC 62313;
– 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 pantograph arrangements, see 5.2 and Clause
A.1.
Range of nominal contact wire height shall be in accordance with Table 1.
Minimum contact wire height shall be calculated in accordance with 5.10.4 of EN 50119:2001
in Europe.
Table 1 – Overhead contact line characteristics for a.c. and d.c. systems

Range of nominal contact wire height 5,0 up to 5,75 5,0 up to 5,5 5,00 up to 5,3
Maximum contact wire height a.c. 6,2 6,0 5,5
Maximum contact wire height d.c 6,2 6,2 5,3
The wind speed and the pantograph length to be considered will be defined by the
infrastructure manager.
Maximum lateral deviation of the contact wire from the track centre line under action of a
cross wind is calculated for pantographs 1 450 mm, 1 600 mm.
The permissible contact wire deviation under the action of a cross wind shall be calculated for
contact wire heights above 5300 mm and/or on curved track. It shall be calculated using the
half-width of the dynamic envelope of the pantograph passage, L . L shall be calculated in
2 2
accordance with Clause A.3.
The smaller value of either 0,4 m or (1,4 – L ) m for 1 600 mm pantograph.

62486 © IEC:2010 – 11 –
5.3 Pantograph characteristics
The geometry of the pantograph is characterised by the following major interaction
parameters (see Table 2):
• 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 the pantograph head (including all
tolerances).
The permissible value for the skew of the pantograph head is 60 mm.
The maximum lateral deviation of the pantograph head is specified in Clause A.3.
Additional characteristics, related to the train, shall also be implemented as follows:
• automatic dropping device;
• minimum and maximum spacing between two operating pantographs;
• an electrical connection between operating pantographs in a.c. systems shall not be used
(except in case of changeover section);
• 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 Clause
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 1. The maximum value of working
height shall be the value which has sufficient margin to infrastructure.
For compatibility between pantographs arrangement and neutral sections, see Clause A.1.
