SIGNON OLAcad. Planning of overhead contact line systems

Software-based, object-oriented and verified.

SIGNON OLAcad is a piece of high-performance project planning software, enabling the quick and efficient planning of overhead line systems in long-distance and local traffic.

SIGNON OLAcad – Planning tool for all kinds of overhead line

Planning overhead lines is a complex and challenging job. Thanks to our high-performance SIGNON OLAcad software, we simplified the processes involved and can plan in an efficient way by using logical relationships between the individual elements. The integration of libraries for different construction methods and drawings allows overhead line systems to be planned regardless of the type in question.

SIGNON OLAcad was developed for the planning of overhead lines on rail lines and in large-scale local and long-distance rail stations, as well as the planning of complex crossings and station yards. With its vast experience and constant desire to drive innovation forwards, SIGNON is your partner for rail-specific software solutions. Make your plans with the professionals - plan with SIGNON OLAcad.
