Switch and crossing for single line operation at double track section
Nihon Kikai Gakkai ronbunshu, 2020 This study aims to develop the switch and crossing for a single line operation at the double track section. First, the authors design and produce the simplified structure of the switch and crossing for passenger trains which can be installed without the ...

Research on Cumulative Deformation Characteristics of Subgrade Filling under Cyclic Train Loading
Shock and Vibration, 2022 The smoothness of high-speed railway is extremely strict. As an important part of the high-speed railway foundation, the subgrade structure has strict deformation requirements.

Railway track design & degradation [PDF]
MATEC Web of Conferences, 2018 The long-term behaviour of railway track has attracted increasing attention in recent years. Improvements in long-term structural performance reduce demands for maintenance and increase the continuous availability of railway lines. The focus of this paper is on the prediction of the sensitivity of a track design to long-term deterioration in terms of ...

Optimisation of grease application to railway tracks [PDF]
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2017 Trackside lubricators are designed to deliver grease to passing wheel flanges to reduce wheel and rail wear on curves. Ensuring that they are set up to deliver sufficient grease for the range of vehicles passing a site can be a challenge. For example, vehicle dynamics modelling and site investigations have shown that the wheels of passenger vehicles do

The interaction between railway vehicle dynamics and track lateral alignment [PDF]
, 2016 Track geometry deteriorates with traffic flow, thus it needs to be regularly restored using tamping or other method. As the deterioration is mainly in the vertical direction this aspect has been widely studied and models for its analysis developed ...

An investigation of sleeper voids using a flexible track model integrated with railway multi-body dynamics [PDF]
, 2009 This article describes a flexible track system model (FTSM) that represents the track structure for a typical ballasted track, taking into account the flexibility of the rails, the sleeper mass and the resilience of the pad/fastening elements, as well as

Assessing the Role of Longitudinal Variability of Vertical Track Stiffness in the Long-Term Deterioration [PDF]
, 2016 The performance of the railway system in terms of dynamic loading is depending mainly on the track support conditions. Usually, the track stiffness is used as the main parameter to describe the support conditions and is defined as the ratio of the load ...

MATEC Web of Conferences, 2017 At present, the most common track model is the one in which rails are presented as bars of infinite length rested on continuous elastic foundation. However, some specialists consider the model to be rather ideal for railways in terms of track and the ...
