Over the past 50 years there has been an increase in the numbers of people jumping/falling in front of trains on the London Underground system. Case-fatality rates have fallen from 70% in the 1950s to 55% today. The proportion certified as suicide has fallen while the proportions certified as accidents or open verdicts have risen. There is unusual clustering of events at some stations which are adjacent to psychiatric units. The hypothesis that ease of access to London Underground stations may sometimes be a determinant of suicide is investigated.
在过去50年里，伦敦地铁系统中跳下/坠入铁轨的人数有所增加。病死率已从20世纪50年代的70%降至如今的55%。被认定为自杀的比例下降，而被认定为事故或死因不明的比例上升。在一些与精神科病房相邻的车站，事件存在异常聚集的情况。本文对伦敦地铁站的便捷可达性有时可能成为自杀决定因素这一假说进行了研究。
