ERTMS (European Rail Transport Management System) was introduced by the European Union to harmonise the nearly 18 different national train control systems which are currently m use, to accelerate the interoperability of the passenger- and freight-transport and, finally, to increase the utilisation of tracks by dynamic train control. The essential components of ERTMS are the train-specific, cellular, professional mobile radio system GSM-R (Global System for Mobile Communication Railway) and the so-called ETCS (European Train Control System) which provides, by its second expansion stage ETCS Level 2, the control-information and signalling-information between the train and the related control location via GSM-R in a connection-oriented and wireless way. This wireless and connection-oriented approach will be the bottleneck of the system, which considerably limits the possible number of voice-connections and data-connections in each cell at the same time and will cause a deadlock of the system, if the number of users will rapidly increase as it could be estimated in case of accidents, freight depots and lines with a high and dynamic volume of traffic. Within this paper the first part of a packet-switched approach is presented to counteract this expected deadlock by taking into account that the GSM-R infrastructure, which is often already installed by the national railroad operators, also should be used to save the high capital vestment of those companies.
