This paper is an outcome of an international collaborative research initiative. Researchers
from 24 institutions across 12 countries were invited to discuss the state-of-the-art in railway …

The paper shows the feasibility of building closed-form and fast-to-evaluate surrogate
models via supervised kernel-based machine learning regressions behaving as digital twins …

Rolling stock connection systems are key to running longer and heavier trains as they
provide both the connections of vehicles and the dam**, providing the longitudinal …

The friction heat generated at the wheel-shoe interface during tread braking operations
leads to a temperature rise of the wheel tread surface. Fast cooling as well as residual …

In this paper, we built a high-temperature superconducting (HTS) maglev vehicle-bridge
coupled system model by Universal Mechanism (UM) software, and analyzed the vertical …

Railway in-train forces are an essential element in assessing multiple aspects of rolling
stocks. Conventional methods for obtaining the forces can be time-consuming and require …

It needs some seconds for a signal, which is created from brake application, to travel from
the first part of the train system (locomotive) to the end part of it (last wagon). Delay in time of …

Heavy-haul transportation plays a significant role in railway freight. Limited by the complex
topography and resource distribution, China's heavy-haul railways contain a great number …

The dynamic performance of three slab ballastless tracks in the China Railway Track System
(CRTS), which is supported by a simply supported box girder under various train loads, were …

Longitudinal train dynamics have a significant impact on both safety and performance of
railway systems. Numerical simulation of long heavy haul trains can thus provide essential …
