This survey has been dealing with the complex system dynamics of pantographs and catenaries. It has turned out that this complex dynamic interaction has become a stumbling block for higher speeds, less wear, higher operational safety as well as reduced (aeroacoustical) noise. A complete understanding of the physical phenomena, a careful mathematical modelling as well as identification of the crucial parameters is mandatory for analysing the shortcoming of the present systems as well as to design and investigate new concepts. As being typical for Europe many different systems are in operation with numerous experiences and unification is slow because of the immense costs involved. Even more advanced computational facilities are needed to predict with a high degree of fidelity the improvements which can be achieved by minor modification of the infrastructure but by courageous steps with new and certainly active pantographs. Consideration of overhead and pantograph as parts of one dynamic system provides a basis for the idea to improve pantographs for better use of existing overhead equipment or less complx quipment for higher speeds. The ultimate extension of this argument from a current collection standpoint is the potential use of a single wire or trolley wire system. With the now existing CAE-simulation tools and the validated models it is also possible to suggest more economical designs for some new electrification projects.
