   Dec 9, 2020 · This study explores the vehicle derailment mechanisms in train-to-train collision accidents. The numerical model of a train-track dynamics system is developed and validated. Vehicle behaviors under a 60 km/h impact indicate that the wheelset has the potential for climbing derailment.

   Can a train derailment cause secondary damage?

   • Numerical investigation on the dynamic b .... Train derailment can cause not only damage to the train itself but also secondary damage to surrounding structures. For this reason, guard rails are commonly used to prevent secondary damage caused by derailed trains on high-risk lines.

   How does a derailment affect the lateral displacement of a vehicle?

   • When a derailment occurs, the motor generally collides with the top of the rail in the vertical direction, and sometimes slides. It cannot help limiting the lateral displacement of a derailed vehicle. However, the friction between the bottom of the motor and the top of the rail can play a positive role in reducing lateral deviation.
