4 Requirements
4.1 General
Doors and hatches of freight wagons shall be designed to be closed and locked.
This remains valid while the freight wagons are in a moving train (unless this is part of the procedure for
discharging the payload).
Suitable and clear instructions for use shall be applied near each locking device and shall be visible by the
operator.
The freight wagon shall bear inscriptions in one or more languages or pictograms showing the relevant
information for safe operation.
Wagons fitted with special equipment (automatic discharging, opening roof, etc.) shall have instructions
concerning operation of this equipment and the safety precautions to be taken, placed in a prominent
position in several languages. If this is not possible these instructions shall be accompanied by
appropriate pictograms.
Specifications regarding such pictograms and information shall be in accordance with EN 15877-1:2024.

This includes forces during loading/unloading (e.g. by gravity loading and unloading).
c
Definition of types of devices, see Clause 3.
For all types of covered freight wagons with sliding side doors, they shall be equipped with suitably
dimensioned devices to prevent any unintended disengagement. The devices shall limit the vertical play
and shall take effect in any operating condition.
4.2 Stresses acting on devices
The closing and locking devices, when closed and locked, shall withstand a force from the inside of the
wagon outwards, representing the forces produced by the payload as well as by additional loads during
operation.
No permanent deformation or loss of functionality shall occur, either on the closing device itself
(discharge door, sliding wall and framework) or on the locking, sliding or guiding components as a result
of these loads except where other pass-fail-criteria are defined.
The load cases shall be in accordance with Annex A.
Stresses acting on devices are:
— stresses which are caused by the payload under normal, regular conditions, by static pressure (bulk)
of the payload and shift of the payload when the payload has been displaced in a foreseeable manner
(see Table 1, Category 1);
— loads which can affect freight wagons during operation. This can be caused during the shunting
process or while the train is moving as well as by pressure differences resulting from aerodynamic
forces during operation (particularly during passing of two trains or at the entrance of tunnels).
NOTE Information for possible additional aerodynamic loads in tunnels is given in EN 14067-3 and
EN 14067-5.
4.3 Safety and operation related requirements
4.3.1 Safeguards of movable protecting devices
Movable items (i.e. doors, sliding walls, sliding roofs, flaps, hoods) shall be provided with automatic safety
devices to avoid any wrong movement in the course of opening and closing operations.
Movable items, (i.e. doors, walls, roofs) shall be designed to be secured against unintentional movement
when placed in their defined position (open, close intermediate) by safeguard devices which shall work
automatically.
The final positions are to be fitted with fixed stops.
Movable items shall be secured positively in their final closing position against unintentional opening by
forces from inside the loading space or exterior forces.
Locking devices shall be used whose status (open/closed) is recognizable. Locking devices shall indicate
their status in a way that can be checked from outside of the freight wagon.
The locking devices shall be designed to be secured against unintentional opening during running.
4.3.2 Actuating of closing and locking devices
The forces, which are needed to actuate the closing and locking devices, shall be of a magnitude that can
be applied by an operator without additional tools. Exceptions are allowable when additional tools are
specifically made available or when motor driven systems are used.
The manual forces, which are needed to actuate the closing and locking devices, shall be of a magnitude
that can be applied by an operator without additional tools. Exceptions are allowable when additional
tools are specifically made available or when motor driven systems are used.
The requirements of EN ISO 13854:2019 shall apply.
Guidance concerning the determination of the maximum permissible manual forces is given in Annex B.
For this, locking devices shall be used which indicate their status (open/closed) and they shall be visible
by an operator outside the train.
4.4 Strength of sliding walls and their locking devices
The sliding walls and their locking devices, when closed and locked, shall resist the load cases in
accordance with Annex A.
4.5 Environmental conditions
The closing and locking devices shall fulfil as a minimum the environmental conditions applicable to the
complete freight wagon in accordance with EN 50125-1:2014.
4.6 Recycling
The closing and locking devices shall be designed to maximize the use of recyclable materials.
5 Maintenance/repair
Wear, failures and other damage may influence the operational safety of freight wagons. Depending on
the wear behaviour, the utilization parameters and the current condition of the railway vehicles, a
maintenance system shall be set up to ensure that the safe functional performance is always achieved.
This shall be included in the rail vehicle maintenance documentation.
The closing and locking systems shall be inspected at defined maintenance periods and remedial action
taken if signs of damage or malfunction are found.
Areas subject to wear shall be accessible for inspection and repair.
Documentation shall be provided on the areas to be inspected and the intervals of inspection.
Maintenance procedures and inspection requirements shall be specified in the maintenance file of the
wagon.
Annex A
(normative)
Strength requirements for freight wagon components and systems for
payload protection
A.1 General
Annex A provides the requirements for the design of freight wagon components and systems for payload
protection against environmental influences and exterior forces. The requirements shall be adopted only
where they are appropriate to the intended application.
The closing, rolling, guiding and locking devices shall withstand the forces transferred to them during the
tests, detailed below.
At the centre of the door a force of 8 kN applies over a 1 m × 1 m area. At each attachment point a force
of 5 kN applies over 300 mm × 1 300 mm area.
No permanent visible deformation or deterioration of the elements for closing, rolling, securing, guiding
and locking shall result from the application of these test loads.
A.2 Strength of sliding walls
a) Sliding walls which are less than 2,5 m long shall meet the same load cases as sliding doors.
b) Sliding walls from 2,5 m to 5 m long shall have a 20 kN load applied at mid-wall over a 1 m × 1 m
area.
