Live tracking is essential in the case of public transportation systems. Furthermore, making public the locations of public transportation units can also be useful. It not only helps the transportation providers, but the clients, as well.A general live tracking framework is proposed. It is applicable for any kind of logistics system. In this study the Romanian railway system is used as a test environment. Train movements are simulated based on timetables.Using the framework a web application is developed. A map service is used for displaying the railway system and the simulation.
