To improve the aerodynamic performance of high-speed trains (HSTs) running in the open
air, a multi-objective aerodynamic optimization design method for the head shape of a HST …

A 3D dynamic model of a high-speed train coupled with a flexible ballast track is developed
and is presented in this study. In this model, each vehicle is modeled as a 42 degrees of …

Wheel flange climb derailment of vehicles in railway turnouts is a serious safety issue. In
particular, derailment accidents in smaller turnouts, caused by poor track alignment before …

Short pitch rail corrugations were observed on a recently opened Chinese high-speed line.
On the basis of field measurements and observations of corrugations occurred on the high …

Lateral collisions between heavy road vehicles and passenger trains at level crossings and
the associated derailments are serious safety issues. This paper presents a detailed …

Operation safety and efficiency of high-speed trains are prone to strong winds. This study
proposes a wind hazard warning system to predict wind speed and provide warning for safe …

Low-frequency hunting problems of high-speed railway vehicles frequently occur due to the
complex operating environment and degradation of wheel–rail contact conditions, which …

The running safety of high-speed trains has become a major concern of the current railway
research with the rapid development of high-speed railways around the world. The basic …

Train collision-induced derailment may result in serious casualties. This study investigates
the railway vehicle derailment behaviour and explores the derailment causes in train-to-train …

Beijing has an enormous transportation challenge: to relieve the extreme congestion that
has arisen, largely due to overpopulation. To meet this challenge, the city administration has …
