The project

The Getzner solution

The ‘Tren Maya’ railway line is located in Mexico and covers a length ofover 1,500 kilometres. It connects
various important tourist sites ofMayan culture as well as cities andbeaches. From mid-2024, the trainson this railway line will transport
goods and around three million
people a year to 20 destinations in
an environment-friendly manner.

Sustainably protected

Alstom Transport is building the42 ‘X’Trapolis’ passenger trainsrequired for this on site in Hidalgo.
Up to 300 passengers per train willbe transported at speeds of up to
160 km/h on the route. In addition topassenger wagons, the trains also
have sleeping and dining wagons.
In order to offer passengers a highlevel of travelling comfort, Alstom
Transport was looking for a floating
wagon floor bearing solution. The aim
was to reliably reduce vibrations andnoise levels. In addition, the clientplaced high demands on fire protection and required the trains to be delivered within a stringent time frame.

Getzner has already equipped thecorresponding railway line in Mexico
with under ballast mats and undersleeper pads to provide lasting protection for local residents, the nature reserve and the railway superstructure
against vibrations and noise from thetrains in operation. “We are delighted
that Alstom has also opted for our vibration mitigation solutions to protect
the interior of its railway wagons,”
says Gert Rhomberg, responsible
product manager at Getzner.

Less is moreBased on the requirements set, theexperts at Getzner selected theideal material to reliably decouple
the floor board of the wagons
from the structure. The design wasoptimised to achieve maximum
vibration protection while keeping

costs, weight and construction height
as low as possible. The solution:
Sylomer® FR. “From experience, weknow that the noise level inside thewagons is reduced by up to 7 dBA
and vibrations by more than 20 dB,”states Gert Rhomberg. In addition,
the material fulfils the high fire
protection requirements with Hazard
Level (HL) 3 conformity in accordancewith DIN EN 45545-2.

Quickly delivered, quickly installed
Within just a few weeks, Getznerdelivered the first batch of elastomer
stripes, which offer a great performance. The fitters from Alstom
in Mexico were also impressedby the ease of installation: “Theinstallation of the Getzner solution
is easy, which saves Alstom a lotof time in assembling. 219 wagons
will be produced until 2026. Thus,time saving is important,” recalls

The Tren Maya line runs fromthe city of Palenque in the stateof Chiapas in south-eastern
Mexico to the tourist resort ofCancún in Quintana Roo via twodifferent routes. The total lengthis 1,500 kilometres.

the Getzner solution compensate
for tolerances in the unfinishedfloor in both length and width
during installation – without
any negative impact on thevibration-insulating properties.

Wagon costs reducedin the long term

© AlstomWith the customised design of theSylomer® FR elastomers, Getzner has
helped to cut both manufacturingand life cycle costs of the wagons.
The reduced vibrations in the interior
are not only much more pleasant for
travellers and train staff. They also
protect joints, electronic components
and sanitary facilities. And thanks tothe consistent material properties of
the Getzner solution over its entire
service life, Alstom Transport can be
sure that this will remain the case fora long time to come.

Increased passenger comfort: Until 2026, Getzner delivers theelastic floor bearings for 219 wagons of 42 Alstom trains.

The lightweight and space-saving solution provides highest comfort tothe passengers and protects electronic components in the long term.

About Getzner
We are proud to be the leading global expert in vibration isolation andprotection for the railway, construction and industry sectors. Our innovative
products are based on our proprietary materials, such as Sylomer®,
Sylodyn® and Sylodamp®, and are complemented by spring elements likeIsotop. Our applications effectively reduce vibrations and noise. They also
reduce wear, extend the service life of the bedded components and help toimprove usability, quality and comfort. We specialise in offering integrated
solutions and targeted services for sustainable vibration isolation, based on
intensive research, climate-friendly production and decades of experience.

Tren Maya is an exciting project invarious dimensions: The line will
be highly frequented and used forboth passenger and freight transport. It runs through a nature conservation area that must be specially protected from vibrations
and noise. Also, the connections
should be as comfortable as they
are reliable, so that road and air
traffic will noticeably shift to rail.
A perfect playground for Getzner
to utilise all its strengths inmaterials and applications:— Comfort for passengers
in the trains— Superstructure protection
for the track— Higher track stability and safety— Protection of the environment

We look forward to hearing from you.
