4 Modes of operation
4.1 Introduction
Before explaining the various generic types of machines it is useful for the reader to understand the
three basic operating modes of a machine on the railway as described in this report, as they have a
significant effect on the type of machine and its compliance process.
4.2 Working mode
When in working mode the machine is protected from interference with all traffic (for example,
passenger and freight trains, locomotives) by operational controls applied to the rules of the
Infrastructure Manager. It is possible, but not always the case, that signalling systems will not be
operational. Safety protection during work is described in more detail in EN 16704-1.

3 limiting infrastructure gauge (tunnel, etc.) 7 vehicle mounted signalling equipment (off)

Figure 1 — Schematic representation of working mode
In working mode a machine is permitted to exceed the vehicle gauge of the track it is on. Planning will
be undertaken to avoid damage to the infrastructure by the machine which may need devices to limit its
movement and/or other operational controls. Another area of planning is whether passenger and
freight trains will be allowed to pass the work site on the adjacent track.
When self-propelled a machine will be operated by a driver/operator who has to fulfil the
Infrastructure Manager’s requirements for the line it is on.

CEN/TR 17498:2020 (E)
4.3 Travelling mode
Where the machine needs to move from one worksite to another worksite, but only on the sections of
track out of service by operational controls applied to the rules of the Infrastructure Manager, then the
machine needs to be within gauge for the line but does not necessarily need to react with signals. This is
called travelling mode. Where the machine is self-propelled it will be operated by a driver/operator
who has to fulfil the Infrastructure Manager’s requirements and the driver/operator needs to be able to
see far enough ahead of the machine to enable the machine to stop within the sighting distance.

3 limiting infrastructure gauge (tunnel, etc.) 7 vehicle mounted signalling equipment (off)
4 signalling block sections 8 train stop for passenger and freight trains
Figure 2 — Schematic representation of travelling mode
4.4 Running mode
This is where the machine is operated under the same rules as a comparable standard railway vehicle.
Not every machine has a running mode. A machine in running mode will be expected to behave and
react to the railway signalling and control systems on the track it is running on in the same way that a
passenger or freight train would be scheduled for operational service.
In running mode a machine can either be self-propelled or towed. When self-propelled it will be driven
by a train driver who has to comply with the signalling systems on the line it is running on, e.g. the
driver has to be able to see and react to the signals, machine is fitted with in cab signalling, etc. When a
machine is not self-propelled in running mode it will be towed and needs to behave with the signalling
system in the same way that is expected for a railway wagon.

3 limiting infrastructure gauge (tunnel, etc.) 7 vehicle mounted signalling equipment (active)
4 signalling block sections
Figure 3 — Schematic representation of running mode
In addition to signalling, machines also need to comply with other infrastructure based control and
detection systems. When in running mode, the machine has to be within, and remain within, the gauge
of the line it is running on to avoid collision with infrastructure or trains/machines on adjacent tracks.
Machines that have a running mode will have similar features to conventional rolling stock (e.g.
locomotives, wagons or multiple units). When a machine is in running mode it will have to be
compatible with the interfaces of the railway it is running on. It should always be considered there will
be differences between machines and railway vehicles, which are discussed in this technical report. The
primary purpose of a machine is the working processes which are different from those for vehicles for
the transportation of passengers and freight.
5 Generic types of machine
5.1 Introduction
5.1.1 Classification - general
The range of machines that are used for railway infrastructure work is extremely varied. Some
examples are shown in Annex A, but these are a small selection and new models are continually being
created. However, there are a few basic principles that can be used to decide what generic type of
machine any particular machine falls into. Principally there are four generic types of machine, and each
machine will ultimately be one of these:
a) Railbound machines;
b) Road-rail machines;
c) Demountable machines and trailers (including road rail trailers);
d) Trolleys and portable machines.
11

---------------------- Page: 13 ----------------------
SIST-TP CEN/TR 17498:2020
CEN/TR 17498:2020 (E)
By a relatively simple series of decisions it is possible to clarify which generic type the machine belongs,
see 5.2.5.
5.1.2 Railbound machines
5.1.2.1 Introduction
Railbound machines tend to be the larger machines and, as the name suggests, remain on the railway
line, i.e. they are delivered to their place of work by use of the railway line. As will be discussed later (in
part 6) this generic type of machine is within scope of the Loc&Pas TSI. In that TSI railbound machines
are referred to as ‘special vehicles’ and it is explained that such machines include infrastructure
inspection machines and on-track machines (OTM).
5.1.2.2 OTM
Railbound machines are built to be able to interact with the signalling and control system for the
railway line they are being used on. If the railbound machine is self-propelled in running mode then it
will need to be fitted with all the in cab signalling systems that a passenger or freight train is fitted with
on that line; for example Indusi, TVM430, AWS, ERTMS, etc. If the machine is hauled in running mode
then it still needs to react with the signalling and control systems in the way that a freight wagon is
expected to; for example, the axle weights and wheel spacing will need to be compatible with the
signalling system, the axle bearings will need to be in a position to be monitored by the hot box
detection systems, etc.
Railbound machines can be self-propelled in running and travelling/working modes, or hauled in
running mode and self-propelled in travelling/working modes, or hauled in both running and
travelling/working modes.
5.1.2.3 Infrastructure inspection machines
The requirements for infrastructure inspection machines within the Loc&Pas TSI are ambiguous, but
the ERA Application Guide to this TSI makes it clear that the manufacturer can decide whether such a
machine should meet the requirements of coaches/wagons or for OTM. It is recommended that
infrastructure inspection machines that are designed to be incorporated into passenger trains should be
considered railway vehicles rather than machines and should comply with the standards applicable to
passenger vehicle(s) concerned. Self-propelled infrastructure inspection machines are similar to OTMs
and it is recommended they should be constructed in compliance with EN 14033 series. This
interpretation aligns with the definition set out in EN 14033-1:2017 3.3.
Additionally there is equipment that is attached to railway vehicles which is used to monitor the
condition of the infrastructure, such as unattended measurement systems. This monitoring equipment
is not considered in the series of standards referred to in 7.2.
5.1.2.4 Converted railway vehicles
Converted railway vehicles where this involves components moving out of vehicle gauge or generating
asymmetric/abnormal wheel loads are now considered as machines and will need to be reassessed as
machines. This is applicable to all new and existing wagons and coaches that are modified by the
fitment of equipment or machines to carry out work on the railway infrastructure.
5.1.3 Road-rail machines
Road-rail machines have the ability to move on their own power on railway track and on the ground. In
general they approach the railway track by land based means and then are used on the track to fulfil
their function. These machines move on the ground by means of either road wheels or caterpillar
tracks. It should be noted that machines which use only sliding rams to get onto the track are not
considered road-rail (and would be classified as a demountable machine). There are examples of
12

---------------------- Page: 14 ----------------------
SIST-TP CEN/TR 17498:2020
CEN/TR 17498:2020 (E)
machines with road wheels that get near to the track and then use sliding rams to position themselves
onto the rails; these are road-rail machines because of the fitment of road wheels (or caterpillar tracks).
A machine that is able to move on the ground should not be taken as meaning that the machine has the
ability (or necessity) for use on a public road. So in some respects the name road-rail is slightly
confusing because it does not confer rights or ability to use a “road”.
Some rail-road machines are designed, intended and permitted to be used on the railway line without
special protection for them, i.e. they have a running mode, these will need to react with the signalling
and control systems as explained in 5.1.2.
5.1.4 Demountable machines and trailers
This generic type of machine is always used in an area separated from passenger or freight trains by
operational means as specified for the railway line it is on. They do not therefore need to interact with
all the signalling and control systems. This means that the machines have to be brought to near the
intended railway worksite and then lifted onto the railway track. Once on the railway track
demountable machines are self-propelled and trailers are hauled along the track.
Road rail trailers have the ability to be moved on railway track and on the ground. In general they
approach the railway track by land based means and then are used on the track to fulfil their function.
The method of movement on the ground is normally by either road wheels or caterpillar tracks. The

Introduction
This document is intended as an explanatory guide to machines that are fitted with rail wheels. It is
written to clarify the complex variety of machines that are used for the construction, maintenance,
inspection, repair and renewal of railway infrastructure. It is intended to be used as an introduction to,
and application guide for, the suite of standards for rail mounted maintenance and infrastructure
inspection machines. It is an aid to clarify which standard to use for a particular machine. This
document does not introduce any new requirements.
Machines are designed and intended for a specific working purpose and their ability to operate as a
railway vehicle is considered as an additional function.
There are various standards which apply to the machines in scope of this document:
— EN 13977
— EN 14033 series
— EN 15746 series
— EN 15955

1 Scope
This document covers machines fitted with rail wheels that are used for the construction, maintenance,
inspection, repair and renewal of railway infrastructure. It is also applicable to machines used for
emergency rescue purposes on railway infrastructure.
NOTE Inspection of the infrastructure includes measurement
This document explains the different modes of operation, classification of machines and which standard
covers the technical requirements. There is also guidance on the compliance process provided to
explain the design review process of different legislation, how these can be combined into one process
(to avoid duplication) and achieve a common understanding of what the design review is achieving.

4 Modes of operation
4.1 Introduction
Before explaining the various generic types of machines it is useful for the reader to understand the
three basic operating modes of a machine on the railway as described in this report, as they have a
significant effect on the type of machine and its compliance process.
4.2 Working mode
When in working mode the machine is protected from interference with passenger and freight trains by
operational controls applied to the rules of the Infrastructure Manager. It is possible, but not always the
case, that signalling systems will not be operational. Safety protection during work is described in more
detail in EN 16704-1.

3 Limiting infrastructure gauge (tunnel etc) 7 Vehicle mounted signalling equipment (off)
4 Signalling block sections 8 Train stop for passenger and freight trains
Figure 1 — Schematic representation of working mode
In working mode a machine is permitted to exceed the vehicle gauge of the track it is on. Planning will
be undertaken to avoid damage to the infrastructure by the machine which may need devices to limit its
movement and/or other operational controls. Another area of planning is whether passenger and
freight trains will be allowed to pass the work site on the adjacent track.
When self propelled a machine will be operated by a driver/operator who has to fulfil the Infrastructure
Manager’s requirements for the line it is on.

FprCEN/TR 17498:2020 (E)
4.3 Travelling mode
Where the machine needs to move from one worksite to another worksite, but only on the line that is
protected from interference with passenger and freight trains by operational controls applied to the
rules of the Infrastructure Manager, then the machine needs to be within gauge for the line but does not
necessarily need to react with signals. This is called travelling mode. Where the machine is self
propelled it will be operated by a driver/operator who has to fulfil the Infrastructure Manager’s
requirements and the driver/operator needs to be able to see far enough ahead of the machine to
enable the machine to stop within the sighting distance.

3 Limiting infrastructure gauge (tunnel etc) 7 Vehicle mounted signalling equipment (off)
4 Signalling block sections 8 Train stop for passenger and freight trains
Figure 2 — Schematic representation of travelling mode
4.4 Running mode
This is where the machine is operated under the same rules as a comparible standard railway vehicle.
Not every machine has a running mode. A machine in running mode will be expected to behave and
react to the railway signalling and control systems on the track it’s running on in the same way that a
passenger or freight train would be scheduled for operational service.
In running mode a machine can either be self propelled or towed. When self propelled it will be driven
by a train driver who has to comply with the signalling systems on the line it is running on, eg the driver
has to be able to see signals, machine is fitted with in cab signalling etc. When a machine is not self
propelled in running mode it will be towed and needs to behave with the signalling system in the same
way that is expected for a railway wagon.

Figure 3 — Schematic representation of running mode
In addition to signalling, machines also need to comply with other infrastructure based control and
detection systems. The machine when in running mode has to be within, and remain within, the gauge
of the line it is running on to avoid collision with infrastructure or trains/machines on adjacent tracks.
Machines that have a running mode will have similar features to conventional rolling stock (eg
locomotives, wagons or multiple units). When a machine is in running mode it will have to be
compatible with the interfaces of the railway it is running on. It should always be considered there will
be differences between machines and railway vehicles, which are discussed in this technical report. The
primary purpose of a machine is the working processes which are different to vehicles for the
transportation of passengers and freight.
5 Generic types of machine
5.1 Introduction
5.1.1 Classification - general
The range of machines that are used for railway infrastructure work is extremely varied. Some
examples are shown in Annex A, but these are a small selection and new models are continuously
created. However there are a few basic principles that can be used to decide what generic type of
machine any particular machine falls into. Principally there are four generic types of machine, and each
machine will ultimately be one of these:
a) Railbound machines
b) Road-rail machines
c) Demountable machines and trailers (including road rail trailers)
11

---------------------- Page: 13 ----------------------
kSIST-TP FprCEN/TR 17498:2020
FprCEN/TR 17498:2020 (E)
d) Trolleys and portable machines
By a reletaively simple series of decisions it is possible to clarify which generic type the machine
belongs, see 5.2.5.
5.1.2 Railbound machines
5.1.2.1 Introduction
Railbound machines tend to be the larger machines and, as the name suggests, remain on the railway
line, ie they are delivered to their place of work by use of the railway line. As will be discussed later (in
part 6) this generic type of machine is within scope of the Loc&Pas TSI. In the TSI they are referred to as
‘special vehicles’ and it is explained that such machines include infrastructure inspection machines and
on-track machines (OTM).
5.1.2.2 OTM
Railbound machines are built to be able to interact with the signalling and control system for the
railway line they are being used on. If the railbound machine is self propelled in running mode then it
will need to be fitted with all the in cab signalling systems that a passenger or freight train is fitted with
on that line; for example Indusi, TVM300, AWS, ERTMS, etc. If the machine is hauled in running mode
then it still needs to react with the signalling and control systems in the way that a freight wagon is
expected to; for example the axle weights and wheel spacing will need to be compatible with the
signalling system, the axle bearings should be in a position to be monitored by the hot box detection
systems etc.
Railbound machines can be self propelled in running and travelling/working modes, or hauled in
running mode and self propelled in travelling/working modes, or hauled in both running and
travelling/working modes.
5.1.2.3 Infrastructure inspection machines
The requirements for infrastructure inspection machines within the TSI are ambiguous, but the ERA
Application Guide to the Loc&Pas TSI makes it clear that the manufacturer can decide whether such a
machine should meet the requirements of coaches/wagons or for OTM. It is recommended that
infrastructure inspection machines that are designed to be incorporated into passenger trains should be
considered railway vehicles rather than machines and should comply with the standards applicable to
passenger vehicle(s) concerned. Self propelled infrastructure inspection machines are similar to OTMs
and it is recommended they should be constructed in compliance with EN 14033 series. This
interpretation complies with the definition EN 14033-1:2017 3.3.
Additionally there is equipment that is attached to railway vehicles which is used to monitor the
condition of the infrastructure, such as unattended measurement systems. This monitoring equipment
is not considered in the series of standards referred to in 7.2.
5.1.2.4 Converted railway vehicles
Converted railway vehicles where this involves components moving out of vehicle gauge or generating
assymetric/abnormal wheel loads are now considered as machines and will need to be reassessed as
machines. This is applicable to wagons and coaches that are modified with equipment or machines to
carry out work on the railway infrastructure.
5.1.3 Road-rail machines
Road-rail machines have the ability to move on its own power on railway track and on the ground. In
general they approach the railway track by land based means and then are used on the track to fulfil
their function. These machines move on the ground by means of either road wheels or caterpillar
tracks. It should be noted that machines which use only sliding rams to get onto the track are not
12

---------------------- Page: 14 ----------------------
kSIST-TP FprCEN/TR 17498:2020
FprCEN/TR 17498:2020 (E)
considered road-rail (and would normally be a demountable machine). There are examples of machines
with road wheels that get near to the track and then use sliding rams to position themselves onto the
rails, these are road-rail machines because of the fitment of road wheels (or caterpillar tracks).
The ability of the machines to move on the ground should not be taken as the machines have the ability
(or necessity) to use on a public road. So in some respects the name road-rail is slightly confusing
because it does not confer rights or ability to use a “road”.
Some rail-road machines are designed, intended and permitted to be used on the railway line without
special protection for them, ie they have a running mode, these will need to react with the signalling and
control systems as explained in 5.1.2.
Road-rail machines are commonly referred to by the initials RRV. They are no longer referred to as
road-rail vehicles but are still known as RRVs.
5.1.4 Demountable machines and trailers
This generic type of machine is always used in an area seperated from passenger or freight trains by
operational means as specified for the railway line it is on. They do not therefore need to interact with
all the signalling and control systems. This means that the machines have to be brought to near the
intended railway worksite and then lifted onto the railway track. Once on the railway track
demountable machines are self propelled and trailers are hauled along the track.
Road rail trailers have the ability to be moved on railway track and on the ground. In general they
approach the railway track by land based means and then are used on the track to fulfil their function.
The method of movement on the ground is normally by either road wheels or caterpillar tracks. There
are examples of trailers with road wheels that get near to the track and then use sliding rams to
position themselves onto the rails, these are road-rail trailers because of the fitment of road wheels (or
caterpillar tracks). A roa
