COMMISSION IMPLEMENTING REGULATION (EU) 2025/2064

of 14 October 2025

amending Regulation (EU) No 321/2013 concerning the technical specification for interoperability relating to the ‘rolling stock – freight wagons’ subsystem of the rail system in the European Union (‘WAG TSI’)

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Directive (EU) 2016/797 of the European Parliament and of the Council of 11 May 2016 on the interoperability of the rail system within the European Union (1), and in particular Article 5(11) thereof,

Whereas:

(1)	Commission Regulation (EU) No 321/2013 (2) lays down the technical specifications for interoperability relating to ‘rolling stock – freight wagons’ subsystem of the rail system in the Union (‘WAG TSI’).

(2)	Commission Delegated Decision (EU) 2017/1474 (3) sets out specific objectives for the drafting, adoption and review of technical specifications for interoperability.

(3)	Pursuant to Article 5(4) of Delegated Decision (EU) 2017/1474 the WAG TSI are to ensure consistency and avoid any overlap with the Regulations concerning the International Carriage of Dangerous Goods by Rail (4) (‘RID’) as regards technical requirements applicable to vehicles.

(4)	To achieve that objective, the European Union Agency for Railways (ERA) identified technical requirements needing to be transferred from RID to TSI WAG as well as initiated a risk analysis to identify new requirements to be addressed.

(5)

In order to harmonise the responsibilities and competences for vehicle authorisation, enhance transparency, improve the quality of the assessment and streamline administrative processes, those RID vehicle requirements should be transferred from RID to the WAG TSI. The assessments of the vehicle prior to authorisation should be performed by a notified body.

(6)

Following several incidents due to a failure to properly secure semi-trailers to the pocket wagon carrying it, several actions to develop solutions ensuring the safe loading, safe transport and overall safe operation involving semi-trailers carried on pocket wagons were initiated. Newly developed technical requirements such as a new interoperability constituent ‘device to secure semi-trailers on pocket wagons’, values and procedures to assess the locking force, indicators showing the locking status, as well as the respective marking on the wagon, should be included in the WAG TSI.

(7)

To ensure safe operation in high crosswind scenarios, it is also necessary to verify the newly developed requirement relating to the vertical upward locking force for the existing and already authorised wagons. This measure was identified by the ERA impact assessment as the least impactful because in case of lack of verification of the locking force for existing wagons, the resulting impact would be the need to exchange the device to secure semitrailers and, if this is not possible, to use another vehicle for the transport of goods other than semi-trailers. The compliance should be marked on the vehicle easily visible for respective parties monitoring or supervising the retroactive application.

(8)

As technologies specifically developed for freight rolling stock, such as the digital automatic coupling, provide different mechanical characteristics as well as digital functions, relating to freight monitoring but also to train protection and train control, it is essential that all requirements related to compatibility with trackside train detection equipment are complied with.The arrangements for integrating possible future requirements, such as the introduction of digital automatic coupling, to carry dangerous goods and equally non-dangerous goods with equivalent or higher safety level should therefore be laid down.

(9)	Furthermore, the Swedish specific case related to hot axle box detectors was reduced in scope, which enhances common requirements at EU level and thus benefits the vehicle authorisation process.

(10)

Under Delegated Decision (EU) 2017/1474, TSIs should indicate whether the conformity assessment bodies which were notified on the basis of a previous version of the TSI need to be re-notified, and whether a simplified notification process should be applied. The amendments introduced by this regulation do not require specific new competences for the conformity assessment and therefore no re-notification of the conformity assessment bodies for the purposes of Regulation (EU) No 321/2013 is necessary.

(11)	The measures provided for in this Regulation are in accordance with the opinion of the Committee referred to in Article 51 of Directive (EU) 2016/797,

HAS ADOPTED THIS REGULATION:

Article 1

The Annex to Regulation (EU) No 321/2013 is amended in accordance with the Annex to this Regulation.

Article 2

The TSI amendments introduced by this Regulation do not require the re-notification of conformity assessment bodies that were notified on the basis of this TSI.

Article 3

This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.

This Regulation shall be binding in its entirety and directly applicable in all Member States.

Done at Brussels, 14 October 2025.

(B) Requirements to comply with point 7.1.2.1.2 of RID

Wagon equipment

The wagon shall be fitted with spark arresters as defined in ERA Technical Document ERA/TD-2024/Spark Arresters version 1.1.

The conformity assessment procedure is set out in point 6.2.2.8.1 of this TSI. This point covers the requirements for WE 6 in accordance with the provisions of RID.

Any wagon intended to be used in potentially explosive atmospheres shall comply with a suitable level of protection which depends on the zones where such wagon is intended to be used.

The zones referred to in the first paragraph of this point are defined in Directive 1999/92/EC of the European Parliament and of the Council (*3).

The level of protection corresponding to the selected equipment group and equipment category is set out in Directive 2014/34/EU of the European Parliament and of the Council (*4). The level of protection for which the wagon is assessed shall be reported in the wagon’s technical file.

(D) Requirements to comply with point 7.1.2.1.4 of RID

Tank-wagons intended for the carriage of dangerous goods shall be built and equipped in such a way as to withstand the impact of collisions that produce stresses exceeding those that occur during normal operating conditions as set out in the specification referenced in Appendix D Index [1].

Construction requirement

The minimum distance between the headstock plane and the most protruding point at the shell extremity on tank-wagons shall be at least 300 mm. This requirement shall not apply to tank-wagons equipped with a central end automatic coupler in accordance with point E.1.2 of this Appendix.

Wagon equipment

This point covers the requirements for WE 1 (D.1) and WE 2 (D.2) in accordance with the provisions of RID.

D.1

Wagons for which code WE 1 is required shall be fitted with devices limiting the impact of collision. Those devices shall be capable of absorbing energy by means of elastic deformation of defined components of the subframe.

The minimum elastic deformation for which the wagon has been assessed shall be recorded in the technical file.

The dynamic energy capacity and assessment procedure depend on the coupler type as specified below:

D.1.1 – Wagons fitted with manual Union Internationale des Chemins de fer (UIC) end coupling system

Minimum dynamic energy capacity: 70 kJ per buffer.

The requirements of this special provision shall be deemed to be met by fitting Category C buffers as set out in the specification referenced in Appendix D Index [32].

This provision shall not apply to wagons fitted with absorption elements in accordance with point D.2.1.

D.1.2 – Wagons fitted with a central end automatic coupler

Minimum dynamic energy capacity: 140 kJ per coupler.

This provision shall not apply to wagons fitted with absorption elements in accordance with point D.2.2.

D.2

Wagons for which code WE 2 is required shall be fitted with devices limiting the impact of collision. Those devices shall be capable of absorbing energy by means of elastic or plastic deformation of defined components of the subframe or by means of a similar procedure (e.g. crash elements).

Both the minimum elastic and plastic deformation capacity for which the wagon has been assessed shall be recorded in the technical file.

The total energy absorption capacity and assessment procedure depend on the coupler type as specified below:

D.2.1 – Wagons fitted with manual UIC end coupling system

Minimum dynamic energy capacity: 30 kJ per buffer.

Minimum total energy absorption capacity (reversible and irreversible): 400 kJ per buffer.

The requirements of this special provision shall be deemed to be met by fitting Category AX buffers as set out in the specification referenced in Appendix D Index [32].

D.2.2 – Wagons fitted with a central end automatic coupler

Minimum dynamic energy capacity: 75 kJ per coupler.

Minimum total energy absorption capacity (reversible and irreversible): 675 kJ per coupler.

(E) Requirements to comply with point 7.1.2.1.5 of RID

Wagon equipment

The fulfilment of Section E.1 or E.2 of this point shall cover the requirements for WE 3 in accordance with the provisions of RID.

E.1 – Prevention of wagon overriding

E.1.1 – Wagons fitted with manual UIC coupling system

The wagon shall be protected against the overriding of buffers by equipment that:

(1)	withstands a vertical force (upwards or downwards) of 150 kN;

(2)	is designed and assessed in such a way that it can prevent the overriding even if the wagon equipment is fitted on only one of the colliding wagons;

(3)	does not increase the overhang for fixing the wagon equipment by more than 20 mm;

(4)

has a width that is at least as big as the width of the buffer head (except for the wagon equipment to protect against the overriding of buffers located above the left-hand footboard, which shall be tangent to the free space for the shunter, although the maximum width of the buffer must be covered);

(5)	is located above every buffer;

(6)	is built in such a way that the risk of penetration of the tank end is not increased in the event of a shock.

E.1.2 – Wagons using a central end automatic coupler

It shall be demonstrated that the central end automatic coupler prevents overriding by remaining in a coupled position and by remaining fixed to the coupled wagons when one side of the coupler is subject to a vertical force of 150 kN transmitted by the wagon upward and downward while the other part of the coupler is maintained in a fixed position.

If this requirement cannot be met, then the consequences of overriding shall be limited by fitting a protective shield at each end of the wagon in accordance with the specification set out in point E.2.2.

E.2 – Wagon equipment limiting the impact from an overriding wagon on the substances being carried when overriding occurs

E.2.1 – Wagons using manual UIC end coupling system

The wagon shall be equipped with a protective shield at each end of the wagon to limit the consequence of overriding buffers.

The width of the protective shield shall:

(1)	be at least as wide as the distance defined by the outside edge of the buffer heads;

(2)	cover the width of the tank.

The height of the protective shield, measured from the top edge of the headstock, shall cover either of the following:

(1)	two thirds of the tank diameter;

(2)	at least 900 mm, provided that in addition the protective shield is equipped at the top edge with an arresting device for climbing buffers.

A protective shield made of mild steel or reference steel with a minimum wall thickness of 6 mm shall provide presumption of conformity.

Reference steel means a steel with a tensile strength of 370 N/mm2 and an elongation at fracture of 27 %.

Mild steel means a steel with a tensile strength between 360 N/mm2 and 490 N/mm2 and an elongation at fracture in % not less than:

If other materials are used, the equivalent thickness shall be calculated in accordance with the following formula:

equivalent thickness = 6

where Rm1 is the tensile strength of the intended material and A1 is the elongation at fracture of the intended material.

The values of Rm1 and A1 to be used shall be the specified minimum values in the standards defining the material properties.

The protective shield shall be shaped and attached in such a way that the possibility of the tank ends being penetrated by the protective shield itself is minimised.

E.2.2 – Wagons using central coupling other than central end automatic coupler not meeting the requirements of point E.1.2.

The wagon shall be equipped with a protective shield at each end of the wagon.

In this case, the protective shield shall cover the tank end to a height of at least 1 100 mm, measured from the top edge of the headstock, the couplers shall be fitted with anti-creep devices to prevent unintentional uncoupling and the protective shield shall be at least 1 200 mm wide over the entire height of the shield.

A protective shield made of mild steel or reference steel as defined in point E.2.1 with a wall thickness of 12 mm shall provide presumption of conformity.

If other materials are used, the equivalent thickness shall be calculated in accordance with the following formula:

equivalent thickness = 12

where Rm1 is the tensile strength of the intended material and A1 is the elongation fracture of the intended material.

The values of Rm1 and A1 to be used shall be the specified minimum values in the standards defining the material properties.

The protective shield shall be shaped and attached in such a way that the possibility of the tank ends being penetrated by the protective shield itself is minimised.
