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.

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.

definition of car-mile versus train-mile causes leads to the hypothesis that longer trains should experience more accidents than shorter trains. FRA accident data were used to develop and test a quantitative metric to objectively characterize different accident causes as either car-mile or train-mile correlated.

- 2 The cause of the Fukuchiyama-Line derailment, and new countermeasures for this accident
It is not too much to say that the history of railway safety in Japan is the history of accidents. We have improved the safety level because we must not repeat the accident that occurred in the past. In this chapter, we explain two accidents that were a turning point for our countermeasures.
Image 2: The mechanism of ATS-P The mechanism of ATS-P systems are that an ATS wayside coil transmits the distance to the red signal for trains. Next, the on-board ATS-P device for trains calculates the continuous brake pattern based on the distance to the red signal. If the train speed exceeds the continuous brake pattern, service brake works auto...
In this chapter, we explain the Fukuchiyama-Line derailment that occurred on West Japan Railway Company.
The evacuation of a quarter of a million residents of the city of Mississauga, Ontario, in the aftermath of the derailment of a freight train carrying hazardous materials on 10 November 1979, was, at that time, the largest peacetime evacuation ever conducted in North America.
