Overview

EN 50367:2020/A2:2025 (CLC) - "Railways applications - Fixed installations and rolling stock - Criteria to achieve technical compatibility between pantographs and overhead contact line" defines the technical compatibility requirements that allow free access of rolling stock to the European railway network. This consolidated European standard (includes Amendment A1:2022 and A2:2025) covers geometry, materials, interaction performance and assessment procedures for the interface between pantographs and overhead contact lines (OCL) to ensure reliable current collection and interoperability.

Key Topics and Requirements

• Geometry and clearances
  • Requirements for infrastructure gauge, contact wire height, gradient, lateral deviation and uplift to ensure safe pantograph passage.
  • Specific pantograph head profiles and conducting ranges are included (annexes provide profiles for head lengths of 1 600 mm and 1 950 mm).
• Interface materials
  • Criteria for contact wire and contact strip materials to achieve reliable electrical contact and acceptable wear behaviour.
• Interaction performance
  • Static contact force, current capacity and dynamic behaviour metrics that affect quality of current collection.
  • Tests and visualisation methods for mean contact forces and quality of current collection.
• Operational requirements
  • Rules for minimum/maximum distances between operating pantographs and arrangement of multiple pantographs on a train.
  • Neutral section design and arrangements to manage electrical phase changes.
• Assessment and testing
  • Procedures for assessing OCL designs and pantograph designs, plus requirements for integrating assessed components into networks and vehicles.
  • Additional DC standstill test methods and specimen calculations (informative annexes) for network evaluation.

Applications and Who Uses It

EN 50367:2020/A2:2025 is essential for:

• Infrastructure managers designing and maintaining overhead contact systems to guarantee network access for interoperable rolling stock.
• Rolling stock manufacturers specifying pantograph geometry, head profiles and contact materials for new vehicles.
• Systems integrators and test laboratories performing dynamic interaction tests, contact force measurements and certification activities.
• Interoperability engineers and procurement teams ensuring vehicles meet network entry conditions and regulatory interoperability requirements.

Practical uses include design checks for OCL layout, selection and assessment of pantograph types, establishing test regimes for current collection quality, and documenting compliance for cross-border operation.

Related Standards

• This EN is published under CENELEC/CLC and complements other European electrotechnical and interoperability standards for railway electrification and rolling stock interfaces. Consult national electrotechnical committees or the CEN‑CENELEC Management Centre for the full suite of related standards and national implementations.

5 Geometry
5.1 General
!This Clause provides requirements for geometric limits of pantographs preventing dewirement and
allowing for adequate interaction performance.
The overhead contact line shall be designed and built in accordance with the geometric characteristics
given in 5.2. The pantograph(s) shall be designed and manufactured in accordance with the geometric
characteristics given in 5.3 and compatible with the type of infrastructure on which it will operate."
The requirements in Clause 5 !apply" to standard gauge applications in accordance with
EN 15273-1:2013+A1:2016, EN 15273-2:2013+A1:2016 and EN 15273-3:2013+A1:2016. These
requirements can be adapted to other track gauges.
5.2 Overhead contact line characteristics
5.2.1 General
The following geometric parameters of the overhead contact line are defined in order to assess technical
compatibility with pantographs whose geometric characteristics are defined in 5.3
• kinematic gauge;
• contact wire height;
• contact wire gradient;
• lateral deviation of the contact wire from the track centre line under action of a crosswind;
• free and unrestricted contact wire uplift at the support;
• neutral section arrangements.
The overhead contact line shall conform to the requirements set out in EN 50119:2020, 5.10.
5.2.2 Infrastructure gauge for free passage of pantograph
The design of the overhead contact line shall allow the operation of vehicles compliant to the appropriate
vehicle gauge for the route. This gauge shall be calculated in accordance with EN 15273-1:2013+A1:2016,
EN 15273-2:2013+A1:2016 and EN 15273-3:2013+A1:2016.
The gauge for free and unrestricted passage of pantographs shall be calculated based on the kinematic
gauge for pantographs in accordance with EN 15273-3:2013+A1:2016, Clause 11. Electrical clearances
requirements shall be as set out in EN 50119:2020, 5.1.3.
EN 50367:2020 (E)
NOTE 1 This calculation covers the lateral movement of the pantograph, the encroachment of the pantograph, the
track gauge and the tolerances.
The design of infrastructure gauge shall allow for unrestricted passage of pantographs with profiles as set
out in Figure A.6 or pantographs with either insulating or conductive horn as set out in Figure A.7.
The determination of the minimum height of structures above the contact line shall be in accordance with
EN 15273-1:2013+A1:2016, 8.1.2. For this, the encroachment of the pantograph head above the contact
plane defined in 5.3.1, !may" be reduced by taking into consideration the maximum possible lateral
position at this location.
NOTE 2 As an example, for bridges the maximum encroachment can be adjusted if the nominal position of contact
wire is at the track centre line.
5.2.3 Contact wire height
The nominal contact wire height shall be chosen inside the ranges given in Table 1.
The contact wire may be higher in certain cases such as level crossings, loading areas, etc. In these cases,
the maximum design contact wire height shall not be greater than 6,20 m.
The maximum contact wire height shall not exceed 6,50 m.
The contact wire height may be lower than the nominal contact wire height in certain cases related to
structure gauges such as bridges and tunnels. Contact wire height shall be within the limits calculated in
accordance with EN 50119:2020, 5.10.
NOTE Aerodynamic effects could necessitate to limit the contact wire height for speed higher than 250 km/h in
order to achieve technical conformity for new traction units.

5.2.4 Contact wire gradient
The permissible contact wire gradient and change of gradient shall be in accordance with Table 1.
The contact wire gradient specified in Table 1 may be exceeded on an exceptional basis, where a series
of restrictions on the contact wire height such as level crossings, bridges, tunnels, etc., prevents compliance.
In this case the assessments requirements of 7.3 shall be replaced by the limits as set out in Table 4 of
EN 50119:2020.
5.2.5 Lateral deviation of contact wire
5.2.5.1 General
The permissible lateral deviation of the contact wire from the track centre line is calculated based on the
working zone of pantograph head for serviceability and on the limit of dewirement (the limit of stability for
lateral interaction).
NOTE 1 Under standard conditions the contact between contact wire and pantograph is inside the limits of
serviceability.
NOTE 2 Under worst conditions, contact inside the limits of dewirement can occur without damages with catastrophic
consequences.
EN 50367:2020 (E)
For checking the stability against dewirement, the permissible lateral deviation of contact wire from track
centre line (d ) shall be calculated in accordance with 5.2.5.2.
lstab
For checking the lateral deviation for serviceability, the permissible lateral deviation of contact wire from
track centre line (d ) shall be calculated in accordance with 5.2.5.3.
lserv
The permissible lateral deviations shall be calculated in accordance with EN 15273-1:2013+A1:2016,
EN 15273-2:2013+A1:2016 and EN 15273-3:2013+A1:2016, considering the movements of pantographs
and track gauge using the reference values set out in EN 15273-1:2013+A1:2016, Table G.1 and
EN 15273-3:2013+A1:2016, Table B.1.
For pantographs according to 5.3, the maximum limit for permissible lateral deviation of the contact wire
from the design value for track centre line, under the action of cross wind shall be defined as minimum of:
— d (5.2.5.2)
lstab
— d (5.2.5.3) and
lserv
— the limit given in Table 2.

NOTE 3 These limits are defined based on long term experiences of the different railways when defining
interoperability.
In the case of a mixed-gauge track (track with three rails), the requirement shall be fulfilled for each p
