IEC 61375-1:2026 applies to the architecture of data communication systems in open trains, i.e. it covers the architecture of a communication system for the data communication between vehicles of the said open trains, the data communication within the vehicles and the data communication from train to the ground. The applicability of IEC 61375-1 to the train network technologies allows for interoperability of individual vehicles within open trains in international traffic. The data communication systems inside vehicles are given as recommended solutions to cope with the said TCN. In any case, proof of compatibility between a proposed train backbone and a proposed consist network will have to be brought by the supplier. IEC 61375-1 might be additionally applicable to closed trains and multiple unit trains when so agreed between purchaser and supplier. This fourth edition cancels and replaces the third edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Extension of train backbone topologies: aggregated and segregated topology; b) Added independent consist orientation check with segregated train backbone topology; c) Introduction of wireless technologies: wireless train backbone and wireless consist network; d) Possibility of virtual networks; e) Definition of data classes and protocol requirements suitable for the OMTS domain; f) New clause about cybersecurity in train communication networks.

This document establishes definitions and evaluation methods for the following wheel-rail contact geometry parameters influencing the vehicle running dynamic behaviour: the rolling radius difference between the two wheels of a wheelset (Δr-function) which serves as a basis for all further calculations; the equivalent conicity function from which are derived: a single equivalent conicity value for a specified amplitude, which is relevant for the assessment of vehicle running stability on straight track and in very large radius curves; the nonlinearity parameter, which characterizes the shape of this function and is related to the vehicle behaviour, particularly in the speed range close to the running stability limit; the rolling radii coefficient, which is used to describe the theoretical radial steering capability of a wheelset in a curved track. Additional information is given about the relationship between the contact angles of the two wheels of a wheelset (Δtanγ-function) and about the roll angle parameter. NOTE Out of the presented parameters only those related to the contact angle are relevant for independently rotating wheels of wheel pairs. Descriptions of possible calculation methods are included in this document. Test case calculations are provided to achieve comparable results and to check the proper implementation of the described algorithms. To validate alternative methods not described in this document, acceptance criteria are given for the equivalent conicity function. This includes reference profiles, profile combinations, tolerances and reference results with tolerance limits. This document also includes minimum requirements for the measurement of wheel and rail profiles as well as of the parameters needed for the transformation into a common coordinate system of right-hand and left-hand profiles. This document does not define limits for the wheel-rail contact geometry parameters and gives no tolerances for the rail profile and the wheel profile to achieve acceptable results. For the application of this document some general recommendations are given.

This document specifies the characteristics for suspension diaphragms to achieve, together with applicable inspection and test methods to be carried out for verification. An air spring system usually consists of a diaphragm (subject of this document) and additional components such as either emergency or additional springs, or both, and other assembly parts. This document does not detail the other components of air suspension or control systems such as air reservoirs, air piping, levelling system, frames, stiffeners, emergency suspension systems or elastic supports (such as series springs), etc., which will affect the diaphragm performance. This document applies to suspension diaphragms (inflated with air) designed to be fitted on railway vehicles and similar vehicles running on dedicated tracks with permanent guide systems, whatever the type of rail and the running surface. These parts are typically made with elastomer, textile fabrics and metallic beads.

This document specifies measurement methods and conditions to obtain reproducible and comparable exterior noise emission levels and spectra for all kinds of vehicles operating on rails or other types of fixed track, hereinafter conventionally called “unit”.
This document is applicable to type testing of units.
It provides measurement procedures for vehicle exterior noise (in general, a vehicle type test is carried out using only a selected subset of these tests):
—     when the vehicle is moving at constant speed;
—     when the vehicle is accelerating or decelerating;
—     when the vehicle is stationary in different operating conditions.
It does not include all the instructions to characterize the noise emission of the infrastructure related sources (bridges, crossings, switching, impact noise, curving noise, etc.).
This document does not apply to
—     the noise emission of track maintenance units while working,
—     environmental impact assessment (collection of data to be used in a prediction method for environmental assessment),
—     noise immission assessment,
—     guided buses, and
—     warning signal noise.
The results can be used, for example
—     to characterize the exterior noise emitted by units,
—     to compare the noise emission of various units on a particular track section, and
—     to collect basic source data for units.
NOTE            Additional guidance is provided in Annex E for measurements in the specific case of urban rail vehicles.

IEC 63341-1:2025 applies to fuel cell power systems installed onboard rolling stock for railway applications (e.g. light rail vehicles, tramways, streetcars, metros, commuter trains, regional trains, high speed trains, locomotives). Fuel cell power systems specified in this document are used for the traction power and the auxiliary supply of railway vehicles such as hybrid vehicles, and in case of use as an auxiliary onboard power source. This document applies to the fuel cell technology called proton exchange membrane fuel cell (PEMFC), with the use of hydrogen as fuel source and the use of air as oxidant source. This document does not apply for hydrogen fuel system which is specified in IEC 63341-2, as HFS is not within the scope of this document. This document does not apply for power conversion equipment which is specified in IEC 61287-1 and is not within the scope this document.
This document specifies:
- the scope of supply and the description of the interfaces (fluidic, electrical, thermal and mechanical) of the fuel cell power system;
- the description of the environmental conditions;
- the specification and description of all the requirements to ensure the fuel cell power system conformance with a railway application;
- the process to validate the fuel cell power system sizing required for a specific load profile;
- the safety, reliability and protection requirements to design the fuel cell power system for a railway application;
- the marking and labelling requirements;
- the requirements related to storage, transportation, installation and maintenance;
- the tests (type, routine and investigation) required to validate the fuel cell power system.
