Rail fatigue crack propagation in high-speed wheel/rail rolling contact
Journal of Modern Transportation, 2017 To study the wheel/rail rolling contact fatigue of high-speed trains, we obtain the distribution of contact forces between wheel and rail by introducing the strain-rate effect.

Positioning of High-speed Trains using 5G New Radio Synchronization Signals [PDF]
, 2018 We study positioning of high-speed trains in 5G new radio (NR) networks by utilizing specific NR synchronization signals. The studies are based on simulations with 3GPP-specified radio channel models including path loss, shadowing and fast fading effects.

Aerodynamics of railway train/tunnel system: A review of recent research
Energy and Built Environment, 2020 The coupling and complexity of railway train / tunnel system are further aggravated by increasing train speed, which produces a series of aerodynamics problems, such as aerodynamic drag, slipstream, pressure wave and micro pressure wave.

Modelling extreme wind speeds in the context of risk analysis for high speed trains [PDF]
, 2002 For high speed trains there is a potential risk of derailment when driving very fast and being hit by an extraordinary strong gust at the same time. The risk depends on both the wind speed and the angle between train and gust.

About the influence of wheel-rail adhesion on the maximum speed of trains
MATEC Web of Conferences, 2018 Wheel-rail adhesion is a fundamental aspect in rail transport, with high impact on traction and braking of trains. In the case of high speeds trains, wheel-rail adhesion is particularly important, as the maximum usable traction force is limited by the ...
