Fault Diagnosis for High-Speed Train Axle-Box Bearing Using Simplified Shallow Information Fusion Convolutional Neural Network [PDF]
Axle-box bearings are one of the most critical mechanical components of the high-speed train. Vibration signals collected from axle-box bearings are usually nonlinear and nonstationary, caused by the complicated operating conditions.

Using High-speed Train Induced Signal to Estimate High-Speed Train Acceleration
Abstract A moving high-speed train (HST) stimulates various seismic waves near a high-speed railroad (HSR). Thus, the HST has been treated as a combined and moving seismic source. Moreover, the speed and acceleration of HST are typical moving parameters for this HST seismic source. Certain devices, such as GPS, Doppler radar, and cameras,

Seamless LTE connectivity in high‐speed trains [PDF]
AbstractHigh‐speed train (HST) is revitalizing the train as a preferred mid‐range transportation system. The provision of broadband Internet connectivity onboard trains is one of the key challenges in the competition among train operators. Unprecedented spectral efficiency and data rates (up to 100Mbps in high mobility) of the Universal Mobile ...
