TSO – pionners in the railway industry

Your partner for railway solutions

With more than 90 years’ experience in France and internationally, TSO puts its expertise to work on:

  • track construction, renewal and maintenance
  • electrification and catenary upgrades
  • survey and rail software development
  • rail safety
  • rail signalling

 

THE STRENGTH OF A CORPORATE GROUP

TSO prioritises innovation and the development of synergies between its own area of expertise and the complementary professions of NGE, enabling the Group to offer a self-delivery service for the most technically demanding projects. This ability to work effectively as a team is perfectly illustrated in the delivery of major projects, such as the Oloron-Bedous rail link and the Luxembourg tramway.

 

A CLEAR COMMITMENT TO THE FUTURE

In 2012, TSO launched its railway training centre at Mézy-Moulins in the Aisne region of France. This training centre is approved by the EPSF (the French Rail Safety Authority) to deliver safety training for COSS (Controller Of Site Safety) and lookout management.

 

WORLDWIDE PRESENCE

With the multiplicity of his activities in France and all over the world, TSO actively participates in the improvement of the modern railway technologies: introduction of concrete sleepers, rail welding, elastic fastenings, continuous welded track, ballastless track and high speed lines…
