title: Suicidal behaviour by train collision in Queensland, 1990-2004.
abstract: OBJECTIVE
  A study on the incidence of suicide in the train system and a description of main characteristics of victims and attempters was commissioned by Queensland Rail in response to an apparent increase of suicide phenomena and their consequences.
  
  
  METHODS
  Two sources of data were used for the analyses: the Queensland Suicide Register (QSR) and the Queensland Rail Incident Surveillance Information System (ISIS). Data on suicide were cross-checked on the two systems for the years 1990-2004. ISIS provided information on cases of attempted suicide for the period 1993-2206.
  
  
  RESULTS
  One hundred and sixty-one train suicide victims were identified. Globally, they represented 2% of all cases of suicide in Queensland. During the examined period no significant changes in trends of suicide through that method were found. Of all suicide cases, 59 (36.6%) included victims aged 15-24 years. The ratio of male :female was 4:1, equal to the sex distribution of suicide with all methods in Queensland. Positive blood alcohol content was found in nearly 50% of young people and in 29.8% of the total sample. A psychiatric diagnosis was documented in 40.4% of all train suicide victims. Only 18 suicide attempters were identified through the ISIS database; of them, 15 were male and three were female, with a gender ratio similar to that of suicide victims.
  
  
  CONCLUSIONS
  This study involved the largest dataset ever published in Australia on this topic. In Queensland, train suicides presented a stable trend during 1990-2004. Subjects of very young age (15-24) seem to be particularly exposed to this method; in this age group one in two individuals had positive blood alcohol content.
