Insights towards Condition Monitoring of Fixed Railway Crossings

Automating condition monitoring of wooden railway sleepers

68 October 2007 EngineerIT This article aims to automate such intuitive human skills for future sleeper inspections. Pattern recognition has been proposed for classification and results from sensors based on the abovementioned methods were fused to generate a single output condition. Final results achieved in this work indicate an overall classification rate of around 88% compared to the human ...

New methods for the condition monitoring of level crossings

Model-based Condition Monitoring for Railway Vehicle Systems

Although modelling techniques for railway vehicle dynamics are well-developed, much of the development in railway vehicle condition monitoring has relied on the knowledge-based techniques where no analytical system model is employed and only qualitative or empirical system knowledge are used for fault diagnosis. In this paper, the model-based approach is proposed as an alternative for railway v...

Condition Monitoring System for Railway Structures in Hammersmith

In this paper, we describe a large scale wireless sensor network (WSN) system installed at Hammersmith Station in the London Underground for monitoring the deterioration due to age of structures. We also describe analysis results of the network topology and the packet loss rate of sensing data using data from the WSN. In this analysis, we examine the train operation affects on the network topol...

Measuring driver responses at railway level crossings.

Railway level crossings are amongst the most complex of road safety control systems, due to the conflicts between road vehicles and rail infrastructure, trains and train operations. Driver behaviour at railway crossings is the major collision factor. The main objective of the present paper was to evaluate the existing conventional warning devices in relation to driver behaviour. The common conv...
