5G-VICTORI: Future Railway Communications Requirements Driving 5G Deployments in Railways
(2021)The complete transformation of the ICT domain driven by 5G network principles and capabilities, will impact significantly the path towards digitalization of many vertical industries, with modern railway transportations ... -
A combined numerical/experimental prediction method for urban railway vibration
(2017)Railway-induced ground vibrations can cause negative effects to people/structures located in urban areas. One of the main sources of these vibrations is from the large vehicle forces generated when train wheels impact local ... -
Comparison of magnitude of actions on track in high-speed and heavy-haul railroads
(2012)In modern high-speed railways the necessity for achieving low life-cycle costs has led to a well-compacted-almost undeflected-substructure. Applications of excellent quality substructure are encountered in the French network ... -

(2015)The overall objective of the Quiet-Track project is to provide step changing track based noise mitigation systems and maintenance schemes for the railway rolling noise. Work package 4 in particular focuses on the combination ... -
A hybrid numerical-experimental assessment of railway ground vibration in urban area
(2018)A common source of railway-induced ground vibrations is local defects such as rail joints, switches, and turnouts which cause large amplitude excitations at isolated locations along the track. Moreover, the distance between ... -
Improving Multiclass Classification of Cybersecurity Breaches in Railway Infrastructure using Imbalanced Learning
(2021)Machine learning approaches and algorithms are spreading in wide areas in research and technology. Cybersecurity breaches are the common anomalies for networked and distributed infrastructures which are monitored, registered, ... -
Influence of the track's stiffness coefficient on the acting loads, deflection and dimensioning of slab track
(2011)Slab Track, as all railway structures, should provide secure train running and smooth passenger ride. Moreover, it should present sufficient vertical elasticity to distribute the loads to the adjacent fixing points of the ... -
Noise reduction in urban LRT networks by combining track based solutions
(2015)The overall objective of the Quiet-Track project is to provide step-changing track based noise mitigation and maintenance schemes for railway rolling noise in LRT (Light Rail Transit) networks. WP 4 in particular focuses ... -

(2016)The overall objective of the Quiet-Track project is to provide step-changing track based noise mitigation and maintenance schemes for railway rolling noise in LRT (Light Rail Transit) networks. WP 4 in particular focuses ... -
Railway-induced ground vibrations in the presence of local track irregularities and wheel flats
(2015)Rapid growth in railway infrastructure has led to numerous environmental technical challenges. This includes ground-borne vibration, which is becoming an increasing problem, particularly in urban environments. A common ... -
Rolling contact fatigue cracking in rails subjected to in-service loading
(2016)Rolling contact fatigue (RCF) is one of the most important failure mechanisms in rails with significant cost- and safety-related implications on the operation of railway systems. In this work, a metallurgical analysis of ... -
Soundscape & land uses management as comprehensive environmental protection action policy tool within the strategic environmental noise mapping in Greece
(2016)Environmental Noise Mapping, as per the relevant 2002/49/EC Directive, is an obligation of all European Union (EU) member states. In the framework of this action in Greece and Cyprus within the Action Noise Plans assessment ... -
Structural impact response for assessing railway vibration induced on buildings
(2017)Over the syears, the rapid growth in railway infrastructure has led to numerous environmental challenges. One such significant issue, particularly in urban areas, is ground-borne vibration. A common source of ground-borne ... -
Vibrations from rail traffic and mitigations measures for the reduction of railway noise
(2015)The present paper presents an analysis of the mechanism of propagation of vibrations from rail traffic and its effects to the surrounding land uses. First, the following issues are examined: levels of noise from rail traffic ...
