Abstract

A successful railway operation depends on providing a reliable service at a competitive price. The accurate matching of the track infrastructure provision and the timetable is central to achieving these requirements. If over provision is made m track infrastructure then the cost of installation and maintenance will be higher that necessary but there will be greater flexibility in operation leading to greater reliability of service; conversely, under provision of infrastructure whilst reducing costs will result in poor service reliability Computer simulation of railway operation is a technique which has been used ^ ^crix^ *™ *°"* "™ *° **"*" ^is balance. This paper describes the VISION simulator plus its associated AC traction supply simulator OSLO The paper also emphasises the flexibility of VISION by describing the way it has been adapted to mee
