Abstract

Starting from the 80’S,the traffic on the rails is continuously increased, as well as the speed of the involved trains: in parallel, also the management of this traffic is become day by day more difficult, imposing to install systems capable to guarantee good performances, quality and high safety level. For each train under control, the traffic managers need to know the \“specific” characteristics (service to be done, composition, weight, length, brake capability.) and the exact position on the line and the speed at each moment: these information are necessary on a regular and continue basis but in case of circulation perturbations their availability in real time and their precision become really vital for the \“rail system”.
