CSCIS03The project "Neue Bahntechnik Paderborn" (NBP) deals with the development of an innovative railroad concept. It envisions short autonomously guided shuttles which are completely automated and even make decisions, for eg., starting only if there is a need. Furthermore the shuttles use the existing rails without differentiating between suburban and long-distance traffic. Thus the passengers needn't change trains during their journey. To save energy while driving, the shuttles unite to form convoys. The question is if it is clever to build a convoy or if the convoy contributes to the energy conservation. Afterwards the shuttles have to initiate the integration, to find each other and to execute the convoy formation. For these procedures it must be declared for how long the shuttles join the convoy, how they find each other and how they exchange information. Particularly the question on which routes and for which average utilisation a convoy formation makes sense. This contribution supplies some beginnings when and under which conditions a convoy travel is meaningful and how communication between the shuttles can be activated and realised.
