Some of the most important materials that need recycling are generated by construction industry. This waste has a multitude disposal problems. In specific case railways, treatment taken from track maintenance and renewal operations is even more challenging. Every year, tons replaced on rail tracks all over world. These kilometres rails, sleepers, ballast can be reused for other purposes. Howeve...

Ground borne vibration in buildings due to railway traffic is a major concern in densely built up areas. In practice, railway induced vibration is often predicted by means of empirical methods such as the Detailed Vibration Assessment developed by the U.S. Federal Railroad Administration (FRA). The vibration velocity level in the free field is predicted based on a separate characterization of t...

High speed trains are currently meant to run faster and to carry heavier loads, while being less energy consuming and still respecting the security and comfort certification criteria. To face these challenges, a better understanding of the interaction between the dynamic train behavior and the track geometry is needed. As during its lifecycle, the train faces a great variability of track condit...

We consider the problem of determining the capacity of a planned railway infrastructure layout under uncertainties In order to address the long term nature of the problem in which the exact future demand of service is un known we develop a timetable free approach to avoid the speci cation of a particular timetable We consider a generic infra element that allows a con cise representation of many...

It is known, that track deterioration (loss of its geometry) strongly depends on track support conditions, particularly on the ballast. In this paper a novel approach is presented to predict the evolution of track vertical irregularities due to vehicle-track dynamic interaction taking into account ballast stiffness with dry friction. An applied vehicle-track model is composed of a railway car a...
