Background: Increasing rail transportation requires appropriate railway suicide preventive measures. Aims: The investigation of trends in railway suicide during 2008-2018, a period in which preventive measures were taken by Dutch railway infrastructure manager ProRail. Methods: Generalized linear regression models for railway suicide were developed for the period 1970-2007 with general suicide rate, railway traffic intensity, and a combination of these variables as regressors. Subsequently, the best-fitting model was used to investigate trends in railway suicide after 2007 by comparing in retrospect observed values with the expected outcomes of the regression model. Results: An adequate regression model for railway suicide was obtained using both general suicide rate and railway traffic intensity as regressors. Based on this model, while national suicide mortality and railway traffic increased, a distinct relative decline in railway suicides was found from 2012 onward. Conclusions: This decline of railway suicides in the Netherlands may indicate that preventive measures taken by ProRail were effective and prevented around 85 railway suicides annually, a reduction of 30%.

荷兰铁路自杀事件低于预期。

背景：增加铁路运输需要适当的铁路自杀预防措施。目的：调查 2008-2018 年期间铁路自杀的趋势，在此期间，荷兰铁路基础设施经理 ProRail 采取了预防措施。方法：开发了 1970-2007 年期间铁路自杀的广义线性回归模型，以一般自杀率、铁路交通强度和这些变量的组合作为回归量。随后，通过回顾性观察值与回归模型的预期结果进行比较，使用最佳拟合模型来研究 2007 年后铁路自杀的趋势。结果：使用一般自杀率和铁路交通强度作为回归量，获得了一个适当的铁路自杀回归模型。基于这个模型，虽然全国自杀死亡率和铁路交通量有所增加，但从 2012 年开始，铁路自杀率明显相对下降。结论：荷兰铁路自杀人数的下降可能表明 ProRail 采取的预防措施是有效的，每年预防了大约 85 起铁路自杀事件，减少了 30%。
