Seeing the lights

The UK rail industry has developed new ways of establishing signal sighting and communicating final designs to train drivers. The approach used on the Channel Tunnel Rail Link, Manchester South project and the Portsmouth resignalling project uses a three-dimensional computer model of the railway that can be used to place signals by parametric design rules and then perform objective assessment of sighting. The software components needed to produce a virtual railway are outlined. The software tools used to meet the signal-sighting requirements are discussed. The static model of the surrounding buildings and the semi-static model for track and overhead equipment are read into the viewer and the signal design model is then passed dynamically. As signals are created, modified or deleted in the three-dimensional model, the interactive view is automatically updated. The data is generated in an industry-standard format widely used for visualisation and simulations systems.
