Railroad capacity and traffic analysis using SIMON

A capacity and traffic flow analysis for trains has been performed using the simulation software tool SIMON. The study comprised a contiguous railroad net in central Sweden. First, bottlenecks in the present traffic flow were found. In the second part, SIMON was used to calibrate two different train schedules for the year 2005. These future train schedules are used as input data for socio-economic studies. Some facts regarding computing speed: The track length was approximately 900 km, with around 220 trains per day, resulting in an average of 24000 train-kilometres per day. On an ordinary Sun Spare IPX, one day was simulated in 9 minutes, 160 times real time.
