From Railway Resource Planning to Train Operation - a Brief Survey of Complementary Formalisations

From seasonal planning via day-to-day train operation to real-time monitoring and control of trains‚ software applications are becoming increasingly integrated. Timetabling implies train traffic. Train staff rosters and train car maintenance are initially derived from timetables and influences future timetables. In this extended abstract we shall sketch a formal model of Railway Nets‚ Timetables‚ Rosters‚ Maintenance‚ Station Interlocking‚ Line Direction Agreement and Automatic Line Signaling. The last three formal models are based on four integrated formal techniques (RAISE‚ Petri Nets‚ Live Sequence Charts and State Charts). The formal sketches are all “backed-up” by either a publication or a research report.
