Track Laying

The challenge 

As the state of infrastructure affects network performance level, operating costs and user comfort, transport authorities and track infrastructure managers must be able to depend on rail infrastructure that is reliable and safe.

The Alstom solution 

With more than 2,000km of track built throughout the world, Alstom has experience in building all forms of rail infrastructure: structures in ballast as well as in concrete, for high-speed lines, traditional lines, metros (on tyres or on metal wheels) or tramways.

Project management adapted to each phase of the building project 

  • Alstom Transport mobilises teams of specialised engineers for each phase of the project: initial concept, global project performance and detailed design (detailed calculation of vibrations for instance),
  • Engineers select the most suitable track components, combining contractual requirements and the infrastructure’s immediate environment,
  • Track laying is carried out on site with the support of local workforce, factories and building tools.

Innovative techniques to reduce disturbances caused by construction

  • Alstom has developed a range of techniques that provide efficient responses to constraints resulting from complex site environments, notably in tunnels, streets or on viaducts,
  • For all light rail building projects (tramways), Alstom proposes its AppitrackTM technology, which accelerates work on tracks and minimises the extent of work on site, reducing the disturbance to urban life.
