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 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.

2 moveable component outside machine gauge 6 track mounted signalling equipment

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.
---------------------- Page: 11 ----------------------
SIST-TP CEN/TR 17498:2020
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.

Key
1 machine 5 signal (with a cross means may be isolated)
2 moveable component within machine gauge 6 track mounted signalling equipment

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.

1 machine 5 signal

2 moveable component locked in machine gauge 6 track mounted signalling equipment

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.
---------------------- 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

---------------------- 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.

2 Moveable component outside machine gauge 6 Track mounted signalling equipment

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.

kSIST-TP FprCEN/TR 17498:2020
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.

2 Moveable component within machine gauge 6 Track mounted signalling equipment

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.

3 Limiting infrastructure gauge (tunnel etc) 7 Vehicle mounted signalling equipment (working)

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. 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)
---------------------- 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

---------------------- 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
