Effectively
isolatingvibrations

Throughout the world, railways help
improve connections between people
and facilitate trade. As the diversityand density of rail traffic grows, so do
the requirements with regard to availability, comfort and environmental
friendliness.

ne of the main problems in railtransportation is posed by the vibrations that are transmitted into theenvironment from the track superstructure, which we perceive as vibrations or structure-borne noise. Anothermain problem is the maintenance expenses that arise from material wearO

due to insufficiently elastic tracks.
Highly elastic products and systems forvibration isolation significantly reducewear-related expenses for superstructure components and vehicles. For almost 50 years, Getzner has developed
technically advanced solutions forvibration isolation.

he product brands Sylomer® andSylodyn® represent the standard
for elasticity in railway superstructures.
The polyurethane materials developedby Getzner are critical components in
the industry for elastic superstructures.
They perfectly satisfy the full range ofrequirements in railway applications,from local traffic to the transport ofheavy goods.

TThe experts at Getzner Werkstoffe work
together with customers to create individual and economical solutions basedon the most recent technical advancements. The sleeper boot systems, railfastenings and refurbishment recommendations for existing track sections
are only a few examples of the trendsetting work in railway superstructures.

Supports for mass-spring systems

Under ballast matshigh level of track elasticity isachieved through installation ofGetzner under ballast mats. The reasons for installing these mats range
from reducing secondary air-borne
noise or providing vibration protection
to preserving the ballast.

AThe respective technical vibration requirements must be carefully considered in selecting the appropriate mat
type. The high effectiveness of Getzner
mats is based on the adapted dynamic
stiffness. They also stand out in termsof quality and economy. They are easy
to handle, can be installed quickly andcan be driven over by heavy construction vehicles. Getzner mats have also
proven themselves well in retrofitting
projects through a special installation
process.
The economic and technical performance of Getzner under ballast matscan be seen around the world in themore than 5 million m2 that havebeen installed so far in:— High-speed lines— Standard-gauge lines— Urban rail systems

Insertion pads forsleeper boots
lab track systems must have sufficient elasticity in order to activate
the load-distributing effect of the rails.
A wide range of options exist for thearrangement of elastic components.

SOne advantage offered by an elasticallysupported sleeper block is reduced
emission of air-borne sound because
the vibration must travel through theadditional support mass. A larger elastic support surface also results in lower
edge pressure.
A two-stage elasticity additionally reduces the pressures in the insertion
pads and saves wear on the rail fastenings. With the ability to manufacture
insertion pads of any desired stiffness,
Getzner can meet the widest possible
range of requirements. The most frequent applications for this system arefound in various types of tunnel sections.

Sleeper pads
leeper pads provide vibration protection, preserve the ballast under
the tracks and lengthen the service lifeof the track. They are used on highspeed tracks, on tracks with high axle
loads and on existing tracks during refurbishment.

SSleeper pads are already installed at
the sleeper factory using an optimized
joining system. This means that no additional work is necessary at the construction site. Installation takes placequickly regardless of the weather andwith minimal line interruptions.
Padded sleepers have proven themselves well, particularly for special track
construction methods, such as forswitches, crossings, transition areas
and expansion compensation, and havebecome the technical standard in manycountries.

odern railway lines are increasingly built as slab track systems.
Highly elastic Getzner baseplate pads
provide elasticity for such tracks. They
are installed between the grooved baseplate and the concrete support slab.

lastic rail pads are placed directly
under the rail base. They have adefined stiffness and increase the elasticity of the ballasted track.

MElastic baseplate pads preserve theload-distributing function of the rails
and reduce vibrations due to wheel andtrack irregularities. The rail head deflection during train passage can be
reduced by adapting the stiffness distribution of the baseplate pad.

EThe improved load distribution yields
greater passenger comfort and lesswear on the superstructure. The increased elasticity has a positive effecton the wearing of superstructure components and rolling stock. Getzner
Werkstoffe offers a full range of rail padin various designs and stiffness – fromstandard-gauge railways to tram lines.

continuous elastic rail base support that compensates for installation-related height differences whilestill remaining economical can be realized using the “continuous rail support”
solution developed by Getzner.

AThe stiffness and deflection of the rails
are precisely defined in advance, andappropriate selection of a material ensures that these targets are met.

Getzner Werkstoffe has successfully
met the specific requirements of projects around the world in more than 50
cities as well as on various high-speedlines.

ypical applications for rail groove
fillers include rail profiles andtracks laid in urban areas that crossroads and other individual transportation routes. The filler profiles can beused to close up the grooves required
for the rail wheel, thereby eliminating asafety hazard for vehicles crossing thetracks.

Additional applications include railroad
crossings and connecting tracks on
factory grounds. Getzner supplies rail
groove fillers for all typical rail profiles.
