Sonneville

What Sonneville does

Sonneville AG is a Swiss engineering company that develops and licenses the patented Low Vibration Track (LVT) system, a slab track technology for railway applications using booted single-block concrete ties embedded in a concrete slab with dual-level elasticity. The technology originated in a 1960s collaboration between founder Roger Sonneville and Swiss Federal Railways (SBB); Sonneville International Corporation (S.I.C.) was incorporated in 1981 to commercialize it globally, and in 2009 the company was acquired by Vigier Holding AG and relocatiated to Müntschemier, Switzerland, becoming SONNEVILLE AG within the Vigier Group. The LVT portfolio comprises eight specialized variants (Standard, HA, S&C, Traffic, Panel, SE, M, and Customized) addressing distinct operational conditions spanning metro tunnels, high-speed mainlines, heavy haul freight, switches and crossings, severe environments, rapid-renewal panels, and RFID-tagged custom configurations. The technology has been deployed across 1,817 km of track on five continents, including three of the world's five longest railway tunnels — most prominently the 114 km Gotthard Base Tunnel — and has accumulated 280 million US GT of heavy haul testing without fatigue damage or geometry drift.

Sonneville serves national railway operators, metro authorities, contractors, and manufacturers worldwide, monetizing the technology through a licensing model that combines royalties on the patented LVT block design and components with project-specific technical advisory, design, and support services. Distribution is executed through direct licensing agreements, a global licensee and agent network, and a February 2025 strategic partnership with voestalpine Railway Systems Nortrak that gives the company scaled manufacturing and market reach in the United States and Canada. Pricing is project-based and not publicly disclosed, reflecting the customized engineering nature of each slab track deployment.

The company operates with a small core team (six employees) and functions as a focused IP-and-know-how licensor rather than a manufacturer, leveraging Vigier Group sister companies such as VIGIER RAIL AG and the worldwide licensee network for execution. Its commercial leverage rests on a four-decade performance track record, multi-jurisdiction homologation, and a portfolio of flagship references (Gotthard Base Tunnel, Marmaray, LA Metro, NYCTA Line 7, Network Rail Canal Tunnel, CCR Metro Salvador, THSRC Nangang) that materially shorten the procurement cycle for new specifications.

Core offering

Sonneville AG develops and licenses the patented Low Vibration Track (LVT) system, a slab track technology consisting of booted single block ties embedded in concrete with dual-level elasticity for railway vibration attenuation. The company licenses the technology to railway companies, contractors, and manufacturers worldwide, providing design, technical know-how, and project-specific engineering support for new construction, track renewal, and specialized applications including tunnels, metros, heavy haul, and switches and crossings.

Product overview

Sonneville offers the Low Vibration Track (LVT) system, a comprehensive portfolio of slab track solutions for railway applications. The core product family includes LVT Standard (the foundational and most widely used product), LVT HA (High Attenuation for superior vibration control), LVT S&C (for switches and crossings), LVT Traffic (rescue vehicle-compatible), LVT Panel (rapid installation for track renewal), LVT SE (Severe Environment), and LVT M (Metro-specific). These products share a common booted single-block tie design with dual-level elasticity for vibration attenuation but differ in dimensions, rigidity, and specialized features for different applications. The portfolio is extended through LVT Customized, offering customer-specific dimensions, elasticity adjustments, and RFID tracking capabilities. The LVT system can be installed in tunnels, at grade, on viaducts, and accommodates various railway conditions from high-speed to heavy haul traffic.

Functional benefit

Brands

• Low Vibration Track (LVT): The LVT system is a booted single block slab track system that provides vibration attenuation for railway tracks. Includes variants: LVT Standard, LVT HA (High Attenuation), LVT S&C (for Switches & Crossings), LVT Traffic, LVT Panel, LVT SE (Severe Environment), LVT M (Metro), and LVT Customized.

Products and services

• LVT Standard The foundation of the LVT portfolio, offering tailor-made slab track solutions with low natural frequencies, excellent structure-borne noise reduction, and individual option flexibility for support rigidity and rail fastening choices. Targeted at railway operators requiring durable vibration-attenuating slab track across diverse project conditions.
• LVT HA (High Attenuation) A further development of LVT Standard with larger dimensions and significantly lower rigidity (6-7 kN/mm support stiffness), achieving performance comparable to light mass-spring systems at reduced installation and maintenance cost. Used by railway operators for projects requiring enhanced vibration attenuation such as the Canal Tunnel in London.
• LVT S&C (for Switches & Crossings) The LVT solution for switches and crossings using dual-level elasticity, offering five different LVT support variants with varying lengths and support stiffness. Each dowel position can be realized for required base plates, enabling adoption of ballasted track turnout layouts on a one-to-one basis.
• LVT Traffic Designed for modern rescue concepts in railway tunnels, enabling emergency vehicles with pneumatic tyres to drive on the track while maintaining all LVT-System advantages including vibration attenuation and providing safe escape routes. Targeted at metro and rail tunnel authorities.
• LVT Panel A solution for track renewal during short maintenance breaks, integrating four LVT supports into a precast slab that can be installed without separating rails and grouted with rapidly hardening concrete for quick trafficability. Targeted at operators needing minimal service disruption during renewal.
• LVT SE (Severe Environment) Extended LVT support with rubber gasket fixing the boot to the concrete block, preventing ingression of fine particles and liquids while maintaining optimized elasticity and vibration attenuation under unfavorable environmental influences. Targeted at installations exposed to harsh operating conditions.
• LVT M (Metro) Compact trapezoidal product for metro applications with axle loads up to 18 tons and speeds up to 100 km/h, designed for easy and economical installation with great flexibility in fastening system choice. Targeted at metro operators including Los Angeles, New York, Seoul, Salvador, and Taipei.
• LVT Customized Customer-specific solutions extending the range of existing LVT applications with individually adapted dimensions and elasticity, available in Low Profile versions reducing construction height by up to 40mm, and optionally equipped with RFID tags for component tracking and maintenance recording. Targeted at operators with constrained clearance or asset management requirements.
