Equipment/​Electrical engineering.

Acting innovatively.

With our technical expertise in equipment/​electrical engineering, we develop and supply the optimum power structure for mainline and regional railways, tramways, urban and industrial railways. We build and renew track systems, signalling and safety engineering technology, telecommunications, electrical power and conductor rail systems. Furthermore we are experts for civil engineering and cable laying.

We also carry out the design and construction planning for overhead line projects. Comprehensive prequalification and the know-how of our trained and examined employees are incorporated into complex equipment projects in the same way as in service and individual projects.

Planning and design

Our own engenieerig company covers all phases of electrical engineering project planning.

  • Planning of overhead line systems
  • Planning & design of 50 Hz projects
  • Structural calculations
  • Soil investigations
  • Development of special solutions
