“Cool” tram extension to the Sonnwendviertel district
Categorie: SDS
“Cool” tram extension to the Sonnwendviertel districtBetween February and December 2019, 2550 meter of new track was built in the urban expansion area Sonnwendviertel in Vienna, including two new stops, making use of a track solution from edilon)(sedra, known as the Sound Damping System (SDS). The 1,1 km extension of Line D not only provides a faster connection to the U1 underground line, it also provides “cooling”. The specifically chosen green track is a significant cooling measure of the city to actively protect the climate.
Sustainable tram
The double track is located next to a park in an area densely built with houses, roads and pavements. The 43 cm thick vegetation layer, mainly consisting of native grasses and herbs, ensures that over 70 percent of the rainwater is stored. This has a very positive effect on the urban water and temperature balance.
The new generation of stray current insulation
The universal track insulation system edilon)(sedra Editack Spray – a solvent-free, thick-layered polyurethane resin liquid plastic – was also used specifically for the 1680 m of green track. The two-component material is sprayed on by machine and forms a viscoplastic and mechanically resistant layer. With a layer thickness of 1 mm, achievable drainage coatings of around 0.1 μS/km per track are possible. This value is therefore significantly lower than the permissible drainage layer of G’= 2.5 S/km per track required by the standard, which was also confirmed by on-site measurements.
Our customer “Wiener Linien” is once again convinced by a high-quality edilon)(sedra solution and the good cooperation with all parties involved. Vienna will continue to expand its public transport and now knows where to find cool track extensions.
The challenge
To design a sustainable tramway, economically as well as ecologically sound and seamlessly integrated into the existing environment. An important long-term aspect here is to best protect the existing infrastructure underground from stray currents.
The solution
edilon)(sedra Sound Damping System (SDS) combined with the unique Editack Spray.
The result
A high-performance track system with durable insulation that provides optimal protection against stray currents while also improving the water and temperature balance in the city… how “cool” is that?!

An elastic track bearing system with optimal performance – economical, ecological, stray current insulating, good structure-borne sound insulation and long service life. LCC in perfection!
Our customer Leipziger Verkehrsbetriebe (LVB) was looking for a state-of-the-art track system with continuously elastic rail bearing that met the requirements for stray current insulation in accordance with DIN-EN 50122-2 and the reduction of structure-borne noise and vibrations. LVB therefore opted for our edilon)(sedra SDS (Sound Damping System) for the tram replacement project “Karl-Liebknecht-Straße” in Leipzig.
In addition to maintaining known principles and meeting the requirements of new standards, simple installation and a good price/performance ratio were also relevant for LVB when looking for a suitable system. A prerequisite for the selection of this system was the usability certificate according to DIN 45673-8 for the entire system. An innovative feature of the tram project in Leipzig was the use of prefabricated tie bars coated with PU foam, a joint development of the LVB and edilon)(sedra, which prevents cracking in the road surface.
A total of 2200 m of track and 3 switches were installed with the modular edilon)(sedra SDS, consisting of 100% recyclable edilon)(sedra Filler Blocks for which an official Environmental Product Declaration (EPD) has been issued. In combination with the plastic-based joint grouting, edilon)(sedra Jointelast PU Extra 25, which remains highly elastic even at low temperatures, the flank adhesion could be ensured with deflection of up to 0.9 mm. All the required measured values, both for vertical rail deflection and leakage current insulation, could be successfully demonstrated in practice. The edilon)(sedra SDS system has already proven itself for more than 8 years on Karl-Liebknecht-Strasse in Leipzig.
The challenge
Development of a durable state of the art elastic track bearing system with proven fulfilment of requirements – regarding rail deflection, structure-borne noise and vibrations as well as stray current insulation.
The solution
edilon)(sedra SDS (Sound Damping System)
The result
An environmentally friendly, durable and economical elastic track bearing system.

For the new major Light Rail projects Line 2 in Kaohsiung and Ankeng Line 1 in New Taipei City, not only a variable track system was sought by the construction companies Chan Chun & Chun-Chi Construction Co., Ltd – our team particularly impressed the responsible project managers with technical know-how and teamwork.
Introduction
The holistic planning of modern track construction projects in urban areas is a comprehensive task that calls for experienced professionals and innovative products, such as our edilon)(sedra SDS-M (Sound Damping System – Modular), to take action. It is a variable track system that ranges from green tracks, sustainability requirements and visual criteria that take into account the use and demands of different road users along the entire line and generally high requirements for noise and vibration protection.
Projects Kaohsiung & Ankeng
Our team convinced by its in-depth technical advice, scientific engineering know-how, installation training and practical support from construction to logistics on site.
The modular edilon)(sedra SDS-M offers the possibility of generating different system stiffnesses and thus different superstructure resonance frequencies by means of elastic system insert strips. Especially in densely built-up and inhabited inner-city areas, this is an essential factor for the acceptance and successful implementation of construction projects. The system also offers high electrical track insulation in accordance with DIN 50122-2 (track/earth) and stands out due to a lightweight, simple and cost-effective design and installation compared to traditional track bearing systems. In Taiwan, point machines, rail drainage boxes and axle counter boxes were also insulated with the modular system after creating detailed design plans and illustrations.
The challenge
Construction work in the cities with over one million inhabitants in compliance with the required superstructure resonance frequency of ≤ 25 Hz, “fail safe” construction method, high electrical track insulation and easy installation without heavy construction machines.
The solution
edilon)(sedra SDS-M (Sound Damping System – Modular).
The result
A modular track system for variable use typically as a grass track and road track but in this project also in the area of railway crossings.
