The numerical prediction of vibration in buildings due to underground railways involves modelling many physical phenomena. Not least these is the dynamic soil-structure interaction that exists between various elements system. majority existing models assume railway tunnel and building’s foundation negligible, with two sub-systems behaving as though they are uncoupled. This paper presents some i...

This paper presents development results of the method of seismoacoustic activity monitoring based on usage vibrosensitive properties of optical fibers. Analysis of Rayleigh backscattering radiation parameters changes, which take place due to microscopic seismoacoustic impacts on the optical fiber, allows to determine seismoacoustic emission sources positions and to identify their types. Results...

Backfill mining is an effective option to mitigate ground subsidence, especially for mining under surface infrastructure, such as buildings, dams, rivers and railways. To evaluate its performance, continual long-term field monitoring of the deformation of backfilled gob is important to satisfy strict public scrutiny. Based on industrial Ethernet, a real-time monitoring system was established to...

Attention to hygienic environments in public spaces is increasing, and we believe that it is important to understand and evaluate this aspect of railways in their role as a means of public transportation. Previously, we carried out investigation regarding types and amounts of airborne microbes (mainly fungi) floating in station precincts as well as evaluating railway passengers’ perception of h...

1 October 2004 is the 40th anniversary of the opening of the Tokaido Shinkansen, the world’s first high-speed railway that marked the start of the era of high-speed rail travel. Ten years ago, the October issue of JRTR 3 published a special feature entitled 30 Years of High Speed Railways. This article summarizes the events in highspeed railways in the last 10 years and discusses their future p...

The main objective of this study is to present a framework developed for assisting Railways to monitor and control the quality of services provided to passengers. The study evaluated the passenger Rail Service quality of Indian Railways by developing SQM (Service Quality Management) model on the basis of SERVQUAL and Rail Transport quality. Three new dimensions (Service Product, Social Responsi...
