|
| Royal in collaboration with Sonneville International Corporation offers design, development and construction |
|
| of low vibration track (LVT) systems for ballastless track for: |
|
| |
|
 Tunnels
Viaducts
At Grade
On floating Slab |
|
| |
|
| Performance Benefits: |
|
| |
|
|
Effective vibration attenuation. |
|
|
|
|
Exceptional lateral resistance and dynamic gauge control resulting from the deep embedment of the wide |
|
| concrete blocks in the track concrete. |
|
|
|
| Highly accurate track geometry resulting from the top-down construction method. |
|
|
|
| Unobstructed track center providing for a more aerodynamic track, a safe walkway for maintenance workers |
|
| or passengers (in case of an emergency) and easy access for cleaning. |
|
|
|
|
Absence of any direct electrically conductive link between opposite blocks. |
|
|
|
| No exposed steel components that may corrode with time. |
|
|
|
| Can be used with any type of fastenings |

| PERFORMANCE & COST BENEFITS: |
|
|
|
| Performance: |
|
|
|
| Effective vibration attenuation. |
|
|
|
| Exceptional lateral resistance and dynamic gauge control resulting from the deep embedment of the wide |
|
| concrete blocks in the track concrete. |
|
|
|
| Highly accurate track geometry resulting from the top-down construction method. |
|
|
|
| Unobstructed track center providing for a more aerodynamic track, a safe walkway for maintenance workers |
|
| or passengers (in case of an emergency) and easy access for cleaning. |
|
|
|
| Absence of any direct electrically conductive link between opposite blocks. |
|
|
|
| No exposed steel components that may corrode with time. |
|
|
|
| Easy access to all components (without the need to cut the rail) if an accidentally damaged component must be |
|
| replaced or if differential settlement of the civil works requires to re-adjust the rail level, which is achieved by |
|
| placing shims inside the rubber boots. |
|
|
|
| Cost Benefits: |
|
|
|
| Competitive component costs. |
|
|
|
| Local manufacturing of the concrete blocks. |
|
|
|
| Except in particular cases, absence of stirrups or reinforcements in the track concrete. |
|
|
|
| No need for expensive form work. |
|
|
|
| High installation rates [an average of 300 metres (1,000 ft) per 10 hour shift has been consistently achieved on |
|
| certain projects], which minimize construction time and the risk for costly schedule overruns. |
|
|
|
| Possibility to operate work trains on the track as soon as LVT has been assembled on the tunnel invert, base slab |
|
| or viaduct deck, which allows E&M and other works to proceed simultaneously with the track work. |
|
|
|
| Proven maintenance free operation, except for standard rail maintenance, resulting in a low life cycle cost. |
