IEC 61375-2-3:2015

IEC 61375-2-3:2015 defines requirements for the Train communication network (TCN) communication profile within electronic railway equipment. For engineering teams, test laboratories, and procurement or compliance specialists, it serves as a focused technical reference for evaluating how train communication functions are structured and assessed. IEC 61375-2-3:2015 is particularly relevant where documentation, verification activities, and technical review must align around predictable network behavior and operational consistency in rail applications.

Overview of IEC 61375-2-3:2015

This document addresses the communication profile used in the Train communication network defined for electronic railway equipment. It is intended to support technical assessment of how communication is organized and applied across train systems, helping teams compare designs against a common compliance reference. In practical workflows, it may be used during engineering documentation review, conformity assessment planning, and product evaluation where network behavior, interface consistency, and system integration need to be checked against a clearly defined railway communications profile.

Compliance applications of IEC 61375-2-3:2015

IEC 61375-2-3:2015 is commonly consulted when railway suppliers, system integrators, and testing organizations need to verify communication-related requirements for onboard equipment and connected train subsystems. It can support laboratory evaluation, design validation, procurement review, and technical compliance checks for projects using train communication network architectures. The document is also useful when preparing engineering specifications or verification plans, especially where consistent communication behavior and documented evaluation are important to the acceptance process.

Importance of compliance with IEC 61375-2-3:2015

Using IEC 61375-2-3:2015 as part of a compliance workflow helps reduce technical risk by providing a defined basis for interoperability and verification. In railway projects, consistent communication profiles can support safer integration, clearer testing criteria, and stronger quality assurance across development and acceptance stages. It may also streamline conformity assessment preparation and procurement decisions by giving stakeholders a shared technical reference for review, validation, and documentation control.

• Communication profile reference for Train communication network planning and review
• Useful for engineering validation, test specification development, and documented evaluation
