The analysis showed that broken rails or welds were the leading derailment cause on main, yard, and siding tracks. By contrast to accident causes on main tracks, bearing failures and broken wheels were not among the top accident causes on yard or siding tracks.

Jun 1, 2023 · In the railway safety context, the systems thinking provides a comprehensive framework for researchers to understand the complexity of causation in railway accidents. Many theoretical bases have been developed to help researchers conduct a systematic causation analysis of railway accidents.
Dec 9, 2020 · Derailment is mainly caused by car body yawing rotation and wheelset lateral and vertical displacements. Yawing and pitching motions of car body influence wheelset displacement significantly. Vehicles with the higher velocity generate more severe derailment behaviour.
Introduction. Since our establishment in 1987, we have been working consistently to improve safety as our most important mission. We must prevent derailments and collisions, because passengers may be injured or killed in accidents. In this paper, we report causes of derailments and collisions that occurred in the past.
There were 17 passenger fatalities in 2018-19, up from 9 in 2017-18. This is the highest number for the last ten years. 13 fatalities occurred on the mainline and 4 on London Underground....
It has been suggested that train accident causes can be classified into two groups, those dependent on train length and correlated with the number of cars in the train, and those independent of train length, corresponding to the number of train-miles operated.

Jan 1, 2011 · This paper analyzes several critical parameters for predicting train derailment risk by using derailment statistics from the FRA accident database and related literature. A general method was developed to assess derailment risk by accident cause and FRA track class.
