on-track machines and infrastructure inspection machines
Note 1 to entry: A similar definition is given in EN 17343:2023, 3.1.7.8.1.
3.2
on-track machines
OTM
machine specially designed for construction and maintenance of the track and infrastructure and used in
different modes: working configuration, travelling configuration, running configuration as a self-
propelled vehicle, or running configuration as a hauled vehicle, when:
— it is running on its own rail wheels,
— it is designed to have characteristics necessary for the operation of track based train detection
systems
Note 1 to entry: A similar definition is given in EN 17343:2023, 3.1.7.8.1.1.
3.3
infrastructure inspection machine
machine used to monitor the condition of the infrastructure which, with the exception of machines which
are incorporated into passenger trains, are considered to be on track machines
Note 1 to entry: Infrastructure inspection machines designed to be incorporated into passenger trains are not
considered as railbound construction machines and will meet passenger car standards.
Note 2 to entry: A similar definition is given in EN 17343:2023, 3.1.7.8.1.2.
3.4
demountable module
removable unit which is capable of being attached with dedicated fastening system to a machine, to
perform a specific function
3.5
semi-permanently coupled machines
machines which require a workshop environment to couple and uncouple (because there is no
operational need or requirement to couple or uncouple between the machines)
3.6
running mode
configuration of a machine when it allows movement along the track, all moveable parts stowed within
the applicable gauge, with the machine interacting with the signalling and control systems
3.7
travelling mode
configuration of a machine when it allows movement along the track closed for work, all moveable parts
stowed (but not secured) within the applicable gauge, and when the machine does not require to interact
with the signalling and control systems (in this condition there is no need to ensure operation of
signalling systems or for cab based signalling equipment)
Note 1 to entry: A machine in travelling mode does not need to meet the operational requirements for the
movement of trains on the railway network.
3.8
working mode
mode when the machine is used to perform any of its permitted designed working tasks
3.9
handrail
barrier used to demark edge of platform or assistance on steps, as shown in Figure E.2
Note 1 to entry: Handrails are also referred to as ‘guard rail’ in prEN 14033-3.
4 Machine categorization
4.1 General rules
The application of all requirements of this document is not possible in every case because of the
differences in the design of machines. The machines are therefore divided into seven categories as shown
in Table 1.
In order to use this document, it is necessary to identify to which category the machine belongs. The
corresponding requirements for each category are defined in Annex A.
Table 1 — Machine categories by maximum running speed

formation
with a speed
< 100 km/h –- Category 4 Category 5
(v) of
Cannot be incorporated
–- Category 6 Category 7
c
into a hauled formation
a
These categories of machines could have restrictions for their position in a train or may
require a protection wagon.
b
These categories of machines are permitted to have a self-propelling function in
travelling and working mode only.
c
These categories of machines only move by themselves or coupled to category 6 or 7
machines
Note 1 The categories are aligned with commission implementing regulation (EU) 2019/773.
Note 2 The Category 1 would be better as v > 100 km/h and categories 2, 4 and 6 v “less than and equal to”
100 km/h (a request has been made to update the EU document).
When a machine is restricted to have a specific position within a hauled formation this shall be described
in the documentation, see 20.4, Table 10, Line a).
4.2 Demountable modules
A demountable module shall be checked for conformity as part of the machine to all relevant clauses in
all parts of EN 14033 when any of the following apply:
a) It has been manufactured or modified to suit the particular machine or type of machine.
b) It is used to carry personnel during running or travelling.
c) It is positioned on the machine by other than gravity or twist locks.
d) It has electrical, pneumatic or hydraulic connections to the machine.
e) It is connected to the machine by twist locks and is used for lifting any load.
f) It is connected to the machine by twist locks and has moveable components which are able to exceed
the gauge profile of the machine.
5 Rolling stock gauge
5.1 General rules
The maximum dimensions of the machine shall correspond to the rules of EN 15273-2:2013+A1:2016 in
accordance with the basic principles set up in EN 15273-1:2013+A1:2016.
The associated rules for each gauge, the corresponding reference profile (e.g. G1) and the critical points
near the limits of this gauge shall be shown in the documentation in accordance with EN 15273-
2:2013+A1:2016, Annex R.
The machine reference profile as shown in EN 15877-2:2013, 4.5.35 shall be marked on both sides of the
machine.
Machines intended to run on infrastructures with a gauge different to the kinematic gauge G1 from
EN 15273-2:2013+A1:2016 shall conform to the specific rules of those infrastructures and the
corresponding restrictions shall be shown in the documentation.
NOTE The G1 profile in EN 15273-2:2013+A1:2016, Figure A.4, meets the cross acceptance gauging
requirements for the majority of mainland European countries.
The details of the running gauge including calculation of the reductions at critical points shall be declared
in the documentation see 20.2, Table 8 Line a) and Line b). All critical points shall be detailed and
dimensioned, an example diagram is given in Annex C.
5.2 Stowing of moveable machine parts in running positions
5.2.1 Component locks
Except as shown in 5.2.2 all moveable parts of the machine that can exceed the gauge defined in 5.1,
including those parts that are prevented from abnormal movement by their operating mechanism safety
features, shall be stowed and held by efficient red painted locks. It is not permitted to paint the machine
red in the areas of the locks. The locks shall be designed so that foreign objects such as pieces of ballast
cannot prevent their locking function. There shall either be two independent locking devices or the
devices shall be designed as a failsafe concept. The locking arrangement shall be described in the
documentation, see 20.2, Table 8, Line c).
When in use all locks shall withstand the foreseeable forces encountered during normal operation or
exceptional operation of the equipment being retained.
The operation of component locks should preferably be controlled from the operator’s working or
running position.
5.2.2 Exemption from locking
Pantographs used for traction and insulated pantographs used for measuring are permitted not to have
locks.
5.2.3 Secondary support
Where a part is able to fall onto the track, slings, chains or similar devices shall
