The relatively high maintenance costs of the ballast track are related to the short lifecycle of
the ballast layer. The current vertical ballast tamping technology (eg, Plasser & Theurer …

Under tie pads (referred to as under sleeper pads outside the United States) are elastic
components that deliver a conformal resilient layer between the crosstie (sleeper) and the …

The production and provision of railway infrastructure causes environmental impacts for
several environmental indicators. The goal of this study is a single-score evaluation for …

Ground vibration and noise have been frequently observed in urban rail transit as a
consequence of severe train-track dynamic interaction. To reduce train-induced vibration …

Ballasted tracks are the commonly used railway track systems with constant demands for
reducing maintenance cost and improved performance. Elastic layers are increasingly used …

In this paper, the effect of different thicknesses of Deconstructed Tires Under Sleeper Pads
(DT-USP) and different Unconfined Compressive Strength (UCS) values of mother rocks of …

This study investigates the possibility of predicting, by means of artificial neural networks
(ANNs), the values of static and dynamic bedding moduli of prototypical under sleeper pads …

Composite sleepers and bearers formed of polymers and sometimes steel or fibre
reinforcement are an alternative to traditionally used timber or prestressed concrete …

This study assesses life-cycle greenhouse gas (GHG) emissions associated with the entire
railway infrastructure network of Austria, a first detailed study for a country, modelled through …

Alternative railway sleeper technologies for replacement of timber are made of materials
possessing a wide range of bending and compressive moduli. This poses a great challenge …
