ABSTRACT
This chapter aims to propose a typology of interconnected networks to management, in comparison with the system of agents that make the interconnection feasible, and their possible evolution. Interconnectivity is a process bringing into contact at least two different network operators and political authorities managing the corresponding institutional territories. Network operation and territorial management scales can be different: there may be a great number of agents with divergent interests. The ‘Chunnel’ experience has repercussions on the approach of existing Connections between railway networks in Europe: some other specialized common subsidiaries operating international services have been created for a few years. Interconnection appears as a result of the exploitation of technological innovation by operators with a commercial purpose. Interconnection projects appear first in town or regional planning documents, and they are more or less imposed on the operators.
