PANDROL QTrack®Vibrations mitigation
PANDROL QTrack Umanjenje vibracija
Many metros and trains run along urban environments though
tunnels. The vibrations transmissibility to the foundations of the
buildings above the tunnel might be controlled to limit the structure
born noise.
The PANDROL QTrack® system can be adjusted to the requirements
in terms of vibration mitigation by adjusting the stiffness of the strip
located below the rail foot. Different levels of stiffness are available:
QTrack® SP (Standard Performance): 1-2 dBv
QTrack® HP (High Performance): 3-5 dBv
QTrack® XP (eXtra high Performance): 8-12 dBv
QTrack® HP on floating slab > 20dBv

PANDROL QTrack® Electrical isolation
PANDROL QTrack Elektro izolovanost
The aims of the electrical isolation are: Cilj elektro izolovanosti je:
Increasing the rail-rail resistance to guarantee the good working of the signaling system / Povećanje izolovanosti
šine kao garant za dobar rad signalnog sistema
Reduce the stray currents which are causing unwanted corrosion / Smanjenje lutajućih struja koje uzrokuju
koroziju
STRAY CURRENTS. CONTEXT / LUTAJUĆE STRUJE. NASTAVAK
Tram, metro & Train powered by electricity Rails are used as conductors for returning traction current
Some current leaks through the ground rather than travelling to the substation via the rails = Stray current
Excessive stray current from track to ground causes problems:
Corrosion of rails, steel reinforcement…
Problem of electro-corrosion of close networks (gas, etc.)

STANDARDS
EN 13146-5:2012 and EN 13481-5:2012 – Railway applications. Track
EN 13146-5 deals about the test methods and procedures whilst EN 13481-5 determine the requirements.
These apply to a complete fastening assembly and it is relevant to signalling currents, not to stray currents control
EN 50122:2010 – Railway applications. Fixed installations. Electrical safety, earthing and return circuit
Part 1: Protective provisions relating to electric shock and safety – nothing to do with stray currents control
Part 2: Provisions against the effects of stray currents caused by DC traction systems
This norm defines a maximum average intensity on the stray current of 2,5 mA/m. This is the unique functional
requirement to avoid electro corrosion in the long term1.
The current is the consequence of an average rail potential, URE divided by an averaged track-to-earth resistance,
RRE
TRACTION SYSTEM DESIGN PART: The average rail potential (voltage) must be lower than 1V averaged
TRACK DESIGN PART: The track-earth resistance must be higher than 0,4 Ω·km
1EN 50122-2 §5.2 Criteria for the protection of the tracks : Experience proves that there is no damage in the tracks over a period of 25
years, if the average stray current per unit length does not exceed the following value: I’max = 2,5 mA/m average stray current per
length of a single track line

QT ELEC SOLUTION / Rešenje QT ELEC
The QT ELEC is an electrical insulation film that provides and improve on the stray current protections and helps to cope
with all the current international standards in terms of electrical resistivity. / QT ELEC je izolaciona folija koja pobojšava
zaštitu od lutajućih struja i u skladu je sa svim standardima koji se odnose na elektro otpornost
There are three QT ELEC levels to be applied depending on the required stray current protection and used rubber
encapsulation:
QTrack® encapsulation
with no additional stray
current treatment
QTrack® encapsulation with
ELEC-L treatment
QTrack® encapsulation with
ELEC-M treatment
QTrack® encapsulation with
ELEC-H treatment
The use of the QT ELEC has been fully tested in different weather conditions by Pandrol CDM Track, both in lab and via insitu measurements, with total satisfaction of several customers
The rail-rail resistance value for signaling purposes is not influenced by the use of the QT ELEC solution

TESTING ON STRAY CURRENTS
EN 50122-2 requires a test in situ over 50m track section:
Difficult to perform for all encapsulations
Difficult to get the results from customers
Limited measurements to construct a robust database.
Pandrol CDM Track has developed an internal procedure to reproduce track
conditions in lab environment:
Small blocks:
Block immersed in water for 72h
Measured in DC voltage
Relation: Rtrack-earth = Rrail-earth/2 + correction to block length
Faster to produce + Larger number of measurements
Different encapsulations with different QT ELEC protection levels are tested
Different conditions are reproduced: dry / wet / 1 day-drying / 3 days-drying
Real track measurements are used to benchmark lab results on small blocks

PANDROL QTrack® Depots, yards and ports (I)
PANDROL QTrack Depoi - Tehn. putničke i kargo stanice, luke (I)
Modern depots and yards are designed to be clean and comfortable open space areas. The running rails are elastically
supported and fastened while embedded into a maintenance-free slab structure for a clean and easy access of both
personnel and different maintenance equipment / Moderni depoi su projektovani kao objektin u slobodnom prostoru.
Koloseci su ugradjeni u konstrukciju ploče, elasticno oslonjeni i pričvršćeni sistemom bez održavanja. Koloseci su lako

The PANDROL QTrack® Embedded Rail System offers the perfect marks to accomplish this purpose:
The system, because of its nature, is a ballastless system in which the ballast bed is substituted by a strong
monolithic and durable slabtrack with no needs of regular maintenance operations like tamping, etc. / Sistem
koloseka je ugrađen u monolitnu ploču koja ne zahteva održavanje kao što je podbijanje.
In addition to this, the QTrack® encapsulation provides a continuous fastening without any discrete clips that
may need possible re-tightenings in the future. / Sistem se bazira na kontinualnom pričvršćenju, bez
pojedinačnog pričvršćenja, te tako nema potrebe za pritezanjem u budućnosti.
The rail is embedded making of the depot a clean and friendly work space area with free and safe movement of
workers and maintenance vehicles. / Utopljene šine čine radnu površinu lako pristupačnom i bezbednom za

PANDROL QTrack® Applications: Tunnels (I)
PANDROL QTrack® Primena: Tuneli (I)
The design of new metro and train projects in tunnels suppose many constraint factors to be taken into consideration: Novi
projekti metroa i tunela za vozove, trebaju uzeti u obzir mnoge faktore ograničavanja :
SAFETY / BEZBEDNOST
Most of the new projects in tunnels should be equipped with a track infrastructure allowing multimodal use (rolling
stock, emergency vehicles...) and an easy evacuation by passengers in case of an accident or disruption
(emergency).
VIBRATIONS MITIGATION / UBLAŽAVANJE VIBRACIJA
The inherent characteristic of the continuous support leads to a smoother distribution of the train loads along the
rail, minimizing the vibrations transmissibility and the structure born noise through the foundations of the buildings in
urban environments
INCREASED TRACK AVAILABILITY / POVEŽANA EKSPOATACIONA RASPOLŽIVOST KOLOSEKA
Metros and suburban systems call for a more and more demanding availability of the track for service, whilst
reducing the window time for maintenance operations. Thanks also to the effect of the continuous support of the
QTrack® system there is a direct reduction of the rail corrugation growth and therefore a reduction of needs of rail
grinding

PANDROL QTrack® Primena: Tuneli (II)
LIMITED DIAMETER OF TUNNEL INVERT / OGRANIČENJE VISINE TUNELSKOG SVODA
There are some cases that the height left for fitting of the track superstructure is limited by diameter of the
tunnel invert. The absence of anchors/dowels in the PANDROL QTrack® system makes possible the rail to be
accommodated within a super reduced slab thickness with only 100mm below the lowest part rail.

PANDROL QTrack® Applications: Stations
PANDROL QTrack® Primena: Stanice
More and more, new stations are becoming part of the culture of the cities as relevant trendsetting architecture buildings.
Among the several properties of the PANDROL QTrack®, the system perfectly integrates into this kind of architecture: Sve više i
više, nove stanice postaju deo kulture gradova i predstavljaju relevantne arhitektonske objekte u trendu. Među nekoliko svojstava
PANDROL Qtrack, sistem se savršeno integriše u ovu vrstu arhitekture:
The track is almost disappearing in the slab, providing an aesthetic and clean finishing aspect / Kolosek skoro nestaje u
ploči, pružajući estetski i čist izgled završne obrade
The system is totally maintenance-free / / Sistem je potpuno bez održavanja
The track surface is easily washable and resistant to industrial waste / Površina koloseka se lako pere i otporna je na
industrijski otpad
35

36.

PANDROL QTrack® Applications: Level crossings
PANDROL QTrack® Primena: Ukrštaji u nivou
There are many train alignments running on ballasted track, most of them in the
outer of the cities. These are still intersecting traffic roads in areas that should
still be compatible for running trains and traffic vehicles.
The use of the PANDROL QTrack® system is intelligently matching the demanding
constraints for both track and traffic operation:
From the trains operation point of view, the design of the track system can be
tuned to meet the required stiffness values. No tamping nor any other disruptive
track maintenance operations are needed
On the road traffic side, the rails are embedded in a slab with strong and durable
road finishing
36

37.

PANDROL QTrack® Maintenance (I)
PANDROL QTrack® Održavanje (I)
RAIL CORRUGATION / NABIRANJE ŠINA
The corrugation is the repetition of a rail wear pattern that leads to a reduced rail and wheel
lifetime as well as to an increase of rolling noise and potentially higher levels of vibration emission.
The use of continuous vertical soft and horizontally rigid embedded rail solutions as the PANDROL
QTrack® have been proven by third and independent studies to be a very effective approach to
control the corrugation growth rate
Corrugation is controlled when δ/y < 3%
Measurements performed after 7/70/700 days of operation have demonstrated this phenomena
