Safety critical functions of the engineered railway need to perform at levels of integrity that are so high that an acceptable failure rate cannot be demonstrated through testing alone. Where such functions need to be implemented in complex programmable electronic systems certain design, build and test requirements are defined in technical...

The noise produced during a train pass-by originates from several different sources such as propulsion noise, noise from auxiliary equipment, aerodynamic noise and rolling noise. The rolling noise is radiated by the wheels and the track and is excited by the wheel and rail unevenness, usually referred to as roughness. The current TSI Noise...

This paper aims to enhance tangibility of the resilience engineering concept by facilitating understanding and operationalization of weak resilience signals (WRSs) in the rail sector. Within complex socio-technical systems, accidents can be seen as unwanted outcomes emerging from uncontrolled sources of entropy (functional resonance). Various...

New railway vehicles in Europe have to comply with noise limits as defined in the Technical Specification for Interoperability (TSI). The pass-by test has to be carried out at a site that fulfills the TSI requirements. The need has arisen to be able to perform TSI pass-by type testing at non-compliant sites. In the ACOUTRAIN project, procedures...

Improved methods for measuring curve squeal and braking noise have been proposed within the ACOUTRAIN project, intended as input to future standards. In this paper an outline of these methods is given and the underlying considerations are explained. The EU TSI regulation limiting noise emission of new rail vehicles does not yet specify limits...

A measurement method for combined roughness, track decay rates and transfer functions derived from rail vibration during a train pass-by was initially developed in the late nineties [1]. This method was later implemented in software tools [2] and applied in several countries for various purposes [3, 4, 5]. Due to the broad application potential...

The aim of this paper is to present an overview of the research concerning human response to vibration conducted in the EU FP7 CargoVibes project. The European Union-funded project CargoVibes involved 10 partners from 8 nations and ran from April 2011 to April 2014. The project was concerned with railway-induced ground-borne vibration affecting...

As part of a recent renovation of the Erasmus bridge in Rotterdam, improvements were made to reduce impact noise caused by trams passing a series of rai! joints. The bridge inciudes several different sections inciuding a bascule bridge and is in an inner city tocation with new adjacent apartment buildings. At request of public transport company...

An exploratory study bas been undertaken to put into perspective future impact of road and railway noise until 2050 in The Netherlands, taking into account potential economic and mobitity growth, noise policy and legislation, demography and technical progress. Estimates were made of average noise levels and numbers of annoyed and sleep disturbed...

Rail dampers and sound absorbing plates have been tested on a high speed railway slab track in a walled cutting at a noise sensitive location. Their noise reduction has been determined from pass-by measurements during service and predicted using BEM calculations. The cutting depth, noise barrier height and configuration vary along the length of...

The capability to find individuals using CCTV cameras is important for surveillance applications at large areas such as railway stations, airports and shopping centers. However, it is laborious to track and trace people over multiple cameras post incident. In this paper, we describe the live demonstration of our interactive re-identification...

Voor een beter functionerend spoor moet het spoorsysteem zo ingericht worden dat grote verstoringen (calamiteiten) beter worden voorkomen en sneller verholpen. Het Operationele Controle Centrum Rail (OCCR) vervult hierin sedert oktober 2010 een belangrijke functie. De vraag is echter of die ervaren meerwaarde ook objectief s vast te stellen. We...

Railway pass-by noise measurements on different types of tracks sometimes display a significant difference between the rise and decrease in rolling noise at the front and the back of the train. This can potentially have different causes. Whilst this may not necessarily be relevant for the total passby noise level, it seems to indicate that the...

Accidents with hazardous materials may threaten the lives of people living in the direct environment of the transportation infrastructure. In many countries, fire brigades play a major role in advising the authorities when they are dealing with issues where hazardous materials are involved. Since emergency responders have to deal with injured...

Track decay rates are measured to characterize the track dynamics for railway noise type testing, but also for other purposes in relation to railway noise. They are often measured statically using hammer response functions on unloaded track, but can also be derived from rail vibrations on loaded track during a train pass-by. There are several...
