Overview

EN 15437-2:2012/prA1 is a draft amendment (prA1, May 2021) to EN 15437-2:2012 prepared by CEN/TC 256. It updates the Part 2 requirements that cover performance and design of on‑board systems for axlebox temperature monitoring. The amendment revises the normative references (Clause 2) and replaces Annex ZA to align the standard with Directive 2016/797 on interoperability of the rail system and the relevant Technical Specifications for Interoperability (TSIs).

This draft is distributed for enquiry and, if adopted, will modify the original standard. It is intended to provide a voluntary means to demonstrate conformity with relevant TSI requirements for freight wagons and locomotives & passenger stock within the limits of the standard's scope.

Key Topics

• Scope: On‑board systems for temperature monitoring of axleboxes as part of axlebox condition monitoring and interfaces with vehicle systems.
• Normative references updated: The amendment replaces Clause 2 references to include key railway standards such as EN 50121‑2:2017 (EMC), EN 50125‑1:2014 (environmental conditions), EN 50126‑1 (RAMS), EN 50128:2011, EN 50129:2018 (safety-related systems), EN 50155:2017 (electronic equipment), EN 61373:2010 (shock & vibration) and EN 61508 (functional safety).
• Annex ZA revision: Establishes the relationship between this standard and the Essential Requirements of Directive 2016/797/EC and clarifies presumption of conformity when cited in the Official Journal for specific TSIs (Freight Wagons and LOC&PAS).
• Status and compliance: The draft highlights that adoption confers a presumption of conformity only while the standard is cited in the OJ and warns about other applicable Union legislation.

Applications

This amendment supports practical deployment and use of axlebox temperature monitoring systems with emphasis on:

• Early fault detection to reduce risk of bearing failures.
• Predictive and condition-based maintenance to optimize lifecycle costs and reduce unplanned downtime.
• Safety and interoperability by aligning performance and interface requirements with TSIs and EU interoperability rules.
• System engineering and verification through referenced RAMS, EMC, environmental, shock/vibration and functional safety standards.

Benefits to railway operators and manufacturers include improved asset reliability, clearer compliance pathways for TSI requirements, and harmonised design expectations across member states.

Related Standards

Relevant standards and regulations referenced or aligned in the amendment include:

• EN 50121-2:2017 (EMC)
• EN 50125-1:2014 (Environmental conditions)
• EN 50126-1 (RAMS)
• EN 50128:2011 and EN 50129:2018 (safety software/electronic systems)
• EN 50155:2017 (Rolling stock electronic equipment)
• EN 61373:2010 (Shock & vibration)
• EN 61508 (Functional safety)
• Commission Regulations / TSIs: Freight Wagons (N° 321/2013 and amendments) and LOC&PAS (N° 1302/2014 and amendments)

For implementers: consult the final adopted text and the Official Journal citation for presumption of conformity, and review the full normative clauses for specific technical obligations once the amendment is published.
