Abstract
First paragraph: In October 1999, an outbound commuter train from London Paddington station passed a red signal and then collided head-on with an incoming express train, resulting in serious loss of life. A public inquiry was set up to discover what had caused the crash. Because a driver had failed to stop at a red signal, visual perception became an important issue for the inquiry. Roger Watt of Stirling University Department of Psychology was called as an expert witness to provide the inquiry with evidence and expertise relating to visual perception. In this interview, he gives some views on his own involvement in that inquiry and the lessons for vision science.
