Abstract

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. 1 Introduction The simulation software tool SIMON was developed by AF-Industriteknik for the Swedish National Rail Administration (Banverket), starting in 1990. It has been in use at AF-Industriteknik since 1991 and at Banverket since 1993, and new releases
