TIFLEX LIMITED: Your partner in research,
development and production of rail pads, baseplate pads, undersleeper pads and ballast
mats for the reduction of vibration in rail track. Tiflex Limited has specialised since
1946 in the manufacture of resilient track support materials and other components which
are designed to reduce ground borne vibration from rail track. We have test apparatus
specially designed and dedicated to the examination of polymers for use in the rail track.
We can examine in detail the response of rail pads to wheel flat impacts. Baseplate pads
and Undersleeper pads are tested at large amplitude and high frequencies (typical of the
track situation) so that the vibration insertion loss can be determined accurately.
Tiflex Limited have some
of the most advanced elastomer testing equipment available anywhere in the world, and our
research is dedicated to finding the most cost-effective solutions for our railway
partners and providing them with the best possible advice, designs and materials.
The quality of our products and dedication to customer service are fundamental
requirements throughout the Tiflex organisation. Tiflex anti-vibration products are
manufactured from the highest quality raw materials with strict quality control at every
stage.
The Tiflex quality management system is assessed regularly and is approved to BS EN ISO
9002. Tiflex is also an authorised and approved supplier to many key railway organisations
both in the U.K. and overseas. 
Rail Pads
The selection of rail pads is an important decision as the rail pad is the only
resilient element in the track which can protect sleepers from damaging impact forces
caused by wheel and rail imperfections.The consistent performance of Tiflex rail pads
provides resilience even under the most unfavourable conditions.
TRACKELAST
FC584 (complies with
Railtrack specification RT/CE/S/052 and UIC 864/5)
This highly resilient grade is available in thicknesses of up to 10.5mm. It is often
used on high speed track where the reduction of impact forces is most important.
Trackelast FC584 is also frequently specified for use on tramwav and mainline
applications.
TRACKELAST FC9
(complies with UIC specification 864/5)
Trackelast FC9 is a little stiffer than FC584 and
is available in thicknesses up to 1Omm. It is primarily specified for use on lower speed
main line tracks.
TRACKELAST FC846 (complies with Railtrack specification
RT/CE/S/052 and UIC 864/5)
An extremely hard wearing grade, Trackelast
FC846 has a relatively high stiffness and is resistant to oil. It is used under very arduous conditions, often on switches and
crossings, and can be used with rigid fasteners.
TRACKELAST FC887 (complies with Railtrack specification
RT/CE/S/052)
Trackelast FC887 can be adapted to suit any
environment. It combines the strength and toughness of ethylene vinyl acetate (EVA) with
the resilience of cork particles in a unique process. The resulting pads are very tough
and durable and resistant to oils. These pads are used on both low and high speed tracks
in thicknesses of up to 1Omm.
TRACKELAST FC128 (complies with Railtrack specification
RT/CE/S/052)
A range of pads made from ethylene
vinyl acetate in either eared or lipped configuration is available. FC128 is a
non-resilient pad installed in areas requiring a very tough and durable material.
Baseplate
Pads
Tiflex Limited have manufactured baseplate pads for
more than 40 years and have a wide range of materials available to suit almost every
application from switches and crossings to vehicle washing plants.
TRACKELAST FC5
FOR TIMBER SLEEPERS
Trackelast FC5 is available in thicknesses up to 1Omm depending upon the degree of
resilience required. Trackelast FC5 is designed to remain unaffected by timber
preservatives.
TRACKELAST FC6 FOR CONCRETE SLEEPERS
Trackelast FC6 is designed to provide a resilient interface between baseplate and concrete
sleeper. Similar to FC5 in stiffness, Trackelast FC6 is also available in thicknesses of
up to 1Omm.
TRACKELAST FC10 FOR OIL RESISTANCE
Trackelast FC10 is recommended for use where there is moderate contamination with
lubricants or fuel oils. Thickness range 5mm to 20mm.
TRACKELAST FC16 FOR ELECTRICAL RESISTANCE
Trackelast FC16 is designed for supporting ceramic electrical insulators. Its high
electrical resistance makes it ideal for use in third rail applications.
TRACKELAST FC26 FOR HEAVILY CONTAMINATED AREAS
Trackelast FC26 is specially formulated to resist attack from aggressive chemicals and
fuel oils. This makes it ideal for use in maintenance bays and vehicle washing plants.
TRACKELAST FC897 BASEPLATE HEIGHT ADJUSTMENT
SHIMS
Trackelast FC897 is a relatively incompressible shimming material. Available in a wide
range of thicknesses, it is used for setting baseplated track to line and level.
Undersleeper Pads
Following pioneering work by Tiflex in 1976, the use of
Trackelast undersleeper pads to reduce vibration from normal ballasted track is now well
established.
Tiflex undersleeper pads are more effective than
baseplated track at reducing vibration because there are no fixed anchoring points In
addition, the rigidity of the sleeper assembly allows greater track deflections without
compromising track stability. Tiflex undersleeper pads typically provide up to 12dB
reduction in vibration transmission at the 63Hz band. Many thousands of these pads are now
in use either on new projects or have been retro-fitted in locations throughout the world.
Tiflex are pleased to provide technical assistance and advice for fitting Trackelast
undersleeper pads into any railway environment.
Ballast Mats
When Tiflex ballast mats are installed under the ballast,
they isolate the track structure from the supporting foundation or substrate and can
attenuate the transmission of vibration by 2OdB or more in most cases.
Trackelast ballast mats are designed to give the optimum static and dynamic properties for
use with main line, urban, light rail and metro axle loads. They are proven to give
reliable performance over a very long service life under any climatic conditions.
Floating SlabTrack Bearings
Being one of the world's foremost suppliers of floating slab
track bearings, Tiflex have a wealth of experience with this technology.
There are two principal designs for Tiflex floating slab track bearings. Discrete bearings
can be installed under pre-cast concrete slabs in the traditional manner. Alternatively, a
soft continuous layer of resilient material, similar to a ballast mat, can be installed.
Concrete can then be cast on top of this layer to create the slab. Tiflex lead the way
with a comprehensive service which includes the design, production and testing of floating
slab track bearings. Our experienced technical staff are pleased to offer advice on any
aspect of their use.
