Designing overhead line systems

SIGNON OLAcad is a high-performance software platform that enables the fast and efficient design of overhead line systems for local and long-distance rail traffic.


Future-proof your design by using BIM methodology

More and more projects in Germany require the use of Building Information Modelling (BIM) – a cooperative form of working in which digital models are created, managed and communicated based on relevant structural information.

To make sure you can meet these requirements in the future, OLAcad supports the BIM design process right from the start.

A design tool for all types of overhead lines

Designing an overhead line system is a complex and demanding task. Our powerful SIGNON OLAcad design software simplifies the design process and makes it more efficient by using logical referencing of individual objects. With integrated libraries for different construction methods and different types of drawings, OLAcad can be used to design all types of overhead line systems.

SIGNON OLAcad was developed for designing overhead contact systems on railway lines and in large railway stations used by both local and long-distance traffic, as well as for designing complex crossings and tram depots. With years of experience and a willingness to drive innovation, SIGNON is your partner for railway-specific software solutions. Design with the professionals — design with SIGNON OLAcad.
