This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 256.

This draft amendment A1, if approved, will modify the European Standard EN 15624:2021. If this draft becomes an amendment,
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of
this amendment into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

European foreword
This document (EN 15624:2021/prA1:2023) has been prepared by Technical Committee CEN/TC 256
“Railway applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
The main changes compared to EN 15624:2021 are:
a) Scope has been modified: G/P changeover device has been included and other informative content
has been moved to new Introduction;
b) new 4.11 “Colours” has been added;
b) the content of Annex B has been modified and changed to normative;
c) new normative Annex C “G/P changeover device” has been added;
d) Annex ZA has been updated.

1 Creation of an Introduction
Add an introduction as follows:
“The purpose of empty-loaded changeover devices is the generation of a load-related signal which
causes the brake performance to be adjusted to the current vehicle mass.
The manually operated empty-loaded changeover devices change their output signal according to the
position of the handles which together with the associated changeover plates serve as interfaces. The
changeover plates read the required information for the operation of the empty-loaded changeover
devices, i.e. brake weights for each position and the relevant changeover mass of the vehicle.
Automatic empty-loaded changeover devices sense a certain load threshold of the vehicle to
automatically adjust the output signal when the mass of a vehicle reaches a defined value. This
threshold is the changeover mass. Below this mass the vehicle’s brake system provides a reduced brake
force. For the changeover mass or more the high brake force applies.
In addition, Annex C of this document contains information on the G/P changeover device, which was
originally covered by EN 15877-1 but is about to be removed from that document. It is intended to
develop a new standard for brake position change over devices, which will adopt these requirements.”
2 Modification to the Scope
Change the scope from
“This document is applicable to empty-loaded changeover devices. The purpose of such devices is the
generation of a load-related signal which causes the brake performance to be adjusted to the current
vehicle mass.

This document specifies the requirements for the design, testing and quality assurance of empty-loaded
changeover devices.”

“This document specifies the requirements for the design, testing and quality assurance of empty-
loaded changeover devices.
This document is applicable to empty-loaded changeover devices.
This document specifies the shape and measures of the G/P changeover device’s plate and handle.”
3 Modification to order of subclauses in Clause 4, “Design and manufacture”
Move the subclause
“4.8. Compressed air quality”
below Table 1, becoming
“4.5 Compressed air quality”.

4 Creation of a new subclause 4.11, “Colours”
Add a new subclause 4.11, “Colours” with the following content.
“The empty-loaded changeover devices of new vehicles shall have the following colours:
— white background of the changeover plate;
— red frame covering the edges of the changeover plate;
— braked weights, the changeover mass and their symbols or describing texts, limit stops and handle
in red.
Deliberately there is no reference to the RAL colour chart to define the colour exactly. Any white or red
may be used.
The empty-loaded changeover plate should contrast from its background and surroundings. This is best
with direct surroundin
