Report on suissetraffic and the UITP World Congress in Geneva

The installation and equipping of the new Löwenstrasse through station in Zurich with the LVT system and LVT points has been in full swing since January 2013. By the middle of March, 50% of the whole station area had already been built.
Then, from around May 2013, the Weinberg Tunnel was be equipped with LVT Standard, as well as LVT HA (high attenuation) which provides the maximum protection against vibrations.

In addition, at certain spots the newly developed LVT traffic will be introduced into the Standard and HA versions. This will facilitate safe track crossing with rescue and maintenance vehicles fitted with pneumatic tyres.

The work on the slab track is scheduled to finish in December 2013. By then, a total of 13.3 km LVT Standard track and 16 points with the LVT system will have been installed.

The existing Line 7 (Flushing Line) in the Metropolitan Transportation Authority (MTA) Network in New York is extended westwards    by 2.1 km (7’000 feet).

Once opened, it will connect the prospering westside area around the Javits Convention Center (Hell’s Kitchen) to the extensive MTA network in Manhattan.

The tunnels and stations have been built
with tunnel-boring machines and are now equipped with the LVT slab track system, starting in November 2013 until mid 2013.

 Therefore 14’000 LVT supports are being installed and also a double crossover is equipped with LVT S&C supports. 

All blocks are produced by our licensee Construction Polymers through their
partner KSA in Portsmouth, Ohio, and
are also assembled there.

After the acceptance through a certified engineering company, the supports are delivered on trucks directly to the
construction site.

LVT traffic - Trafficability on ballastless track redefined

A mobility concept on rails

A new type of low vibration track (LVT) system now exists: with LVT traffic, vehicles with pneumatic tyres can also run on ballastless track.  

Modern rescue concepts are frequently based on vehicles running on pneumatic tyres going into tunnels. LVT traffic makes this possible: the combined track is realized by an additional cast-in-place concrete layer and newly developed LVT supports. These have high shoulders and can be separated from the cast-in-place concrete layer with special developed formwork covers. This means that LVT traffic displays the same exceptional behaviour in terms of track deflection and vibration mitigation as all previous LVT solutions. 

The advantages:

- With excellent vibration attenuation and dual
   level elasticity, LVT traffic has the typical
   properties of an LVT system
- All components can be easily replaced
- The solution does not depend on track
   geometry
- The track can be assembled easily and
   efficiently without precast elements
- The construction process is in line with
   conventional ballastless track construction
   methods
