Train derailments are important safety concerns, and they become increasingly so when dangerous goods (DG) are involved. One way to reduce the risk of DG derailments is through effective DG railway car placement along the train consist. This paper investigates the relationship between DG railway car placement and derailment for different route attributes and DG shipments. A model is presented for estimating the probability of derailment by position, based on the estimated point of derailment (POD) and the number of cars derailing. A DG placement model that considers in-transit derailment risk is shown to provide a sound scientific basis for effective DG marshalling in conventional rail hump yard operations.
列车脱轨是重要的安全问题，当涉及危险货物（DG）时，问题更加严重。减少 DG 脱轨风险的一种方法是通过在列车中有效放置 DG 铁路车辆。本文研究了不同线路属性和 DG 运输条件下 DG 铁路车辆放置与脱轨之间的关系。提出了一种基于估计的脱轨点（POD）和脱轨车辆数量来估计位置脱轨概率的模型。结果表明，考虑运输中脱轨风险的 DG 放置模型为传统铁路驼峰场作业中有效的 DG 调车提供了合理的科学依据。
