Introduction
Failed axle bearings on rolling stock create a hazard to the safe operation of the railway. If an axle
bearing fails whilst rolling stock is in-service there is the potential for a catastrophic event. A
catastrophic event may result in fatalities, severe damage to rolling stock and/or the infrastructure and
a risk that rolling stock may derail and/or a fire may develop.
One indication that a bearing is about to fail is a rise in the heat generated by the bearing. Bearings that
are about to fail may therefore be detected by monitoring their temperature to identify an unacceptable
rise.
World-wide experience shows that one way of managing the risk is by installing trackside Hot AxleBox
Detectors (HABDs) to monitor the in-service temperature of rolling stock axleboxes.
The sensors of a trackside HABD measure the thermal radiation emitted from the axleboxes of in-
service rolling stock. The level of thermal radiation is influenced by the emmissivity of the axlebox
surface, which is influenced by the material, design, surface finish and operational conditions (dust,
rain, etc). Even though operational conditions are continually changing the surface emmissivity of the
axlebox, long term experience indicates that such changing conditions can be tolerated.
This part of EN 15437 covers the monitoring of axlebox temperature by trackside HABD. It was
developed by Working Group 35 "Hot Box Detection" of CEN Technical Committee 256 Railway
Applications. It defines the minimum requirements for the interface between a trackside HABD and
rolling stock, to ensure that the system works. It is important to note that Clause 1, Scope, sets out the
minimum requirements for the interface.
The requirements set out in this document are based on long term existing rules, practices and
procedures developed and currently in use by European member railway undertaking’s (RUs) and
infrastructure managers (IMs).
The following principles have been applied:
a) The railway system requires technical rules in order to ensure an acceptable interface between
rolling stock and trackside HABD.
b) In view of the increasing significance of international traffic, the standardisation of this interface is
required.
c) It is of particular importance that the existing level of safety and reliability is not compromised.
d) The Cartesian co-ordinate system is used to define dimensions and positions, that is X is
longitudinal, Y is lateral and Z is vertical.
Some rolling stock, according to their performance or design, is fitted with on-board equipment to
monitor axle bearings for potential overheating. However, in most cases, axle bearings continue to be
monitored by trackside Hot Axle Bearing Detectors which is the subject of this standard.
!EN 15437-2:2012+A1:2022 covers on-board temperature monitoring of axle bearings."
Alternative technology is available, or being developed, to monitor the condition of axle bearings, using
vibration sensors, thermocouples, etc. and may in the future be addressed by additional parts to this
standard.
1 Scope
This part of EN 15437 defines the minimum characteristics for the interface between a trackside Hot
Axlebox Detector (HABD) and Rolling Stock (RST) that comply with the European Directives for
Interoperability to ensure that the minimum functional requirement of the interface is achieved.
The minimum requirements of the interface apply to:
a) Rolling stock conforming to standard European railway gauge, that is 1 435 mm;
b) Rolling stock axles fitted with outboard bearings;
NOTE 1 The design of rolling stock axles fitted with inboard bearings should respect the requirements set
out in Note 2 of 5.2.
c) !Rolling stock with a maximum design speed lower than 250 km/h";

NOTE 2 Interoperable rolling stock !with a maximum design speed higher than or equal to
250 km/h" are mandated to have on-board equipment for axlebox condition monitoring. The requirements
for on-board equipment are described in !EN 15437-2:2012+A1:2022".
