Times of downturn in economy, tough competition, high costs, and large amounts of capital required for replacements have created growing need for cost cutting measures and for seeking better return on investment. This has also placed an increasing emphasis on maintenance practices to extend the service life of existing railroad bridges. This paper outlines the various factors which playa role i...

Railway traffic is a significant source of vibration that can affect the quality life people living near busy railways. This study proposes an integrated methodology for analysing impact vibrations from railway on and nearby buildings measures reducing their effects. The research includes both in-situ measurements numerical modelling traffic-induced vibrations. proposed methodological approach ...

The field is huge, roughly the size of 300 football pitches. Despite its size, it is entirely surrounded by a fence. The fence is only interrupted at one place, by an imposing brick gatehouse with an arch. Somewhat incongruously, a railway line runs under the arch. The railway continues some way into the field, and then comes to an end in a siding. There are dozens of large huts, or block house...

The Epping to Chatswood Rail Link (ECRL) commenced operating in 2009. At the Chatswood end of the project, the railway corridor contains two existing tracks (with conventional ballast and sleeper design) and two new concrete slab tracks, the design of which incorporates sections of low stiffness rail fasteners and floating slab track. During commissioning, noise measurements were undertaken at ...

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...
