The resource requirements and environmental impacts of rail infrastructure [PDF]
The transport sector is one of the main contributors to climate change. Amongst all types of transport modes, the railway is considered as the greenest one and therefore has been expanded in many countries to decarbonize their transport sector.

Temperature Features of CRTSII Slab Ballastless Track in Severe Cold Region
Damages, such as slab end warped, gaps of slab and bed, and cracks of track bed, of CRTSII Slab-Ballastless-Track (SBT) in high speed railway were studied for temperature changing significantly in severe cold regions. First, Contact-Thermal- Resistance (CTR) between Concrete-Asphalt (CA) mortars of the SBT and roadbed were defined.

Efficient quantifying track structure cracks using deep learning
Abstract High‐speed railway ballastless track structure crack detection usually has a high demand for the efficiency of crack detection technology. To overcome the limitation that current crack quantification methods usually require multiple steps, this paper proposes an efficient quantification method for track structure cracks using deep learning ...

Comparison of the Structural Performance of Ballasted and Non-Ballasted Pavement of the Railway with the Help of Beam Models on Elastic Bed and Finite Element Model [PDF]
Today, many countries are opting for ballast less paving of railways using concrete line slabs as an alternative. Ballast paving is particularly prevalent in high-speed lines, urban railways, as well as bridges and tunnels designed for high loads and ...

Parallel computing aided analyses of dynamic buckling for railway track infrastructure
Abstract This paper presents a scalable parallel computing framework for simulating track buckling under dynamic train loads, enabling large‐scale railway track stability analysis. A three‐dimensional (3D) track model is developed using finite element‐based Euler–Bernoulli beam formulations for rails, dynamic force inputs, and nonlinear interactions at
