A condition-based maintenance methodology for rails in regional railway networks using evolutionary multiobjective optimization
Case study line Braşov to Zărneşti in Romania
In this paper, we propose a methodology based on signal processing and evolutionary multiobjective optimization to facilitate the maintenance decision making of infra-managers in regional railways. Using a train in operation (with passengers onboard), we capture the condition of

Rail Condition Monitoring using Axle Box Acceleration Measurements
Defect detection in the Netherlands and Romania
In this paper we discuss rail condition monitoring based on axle box acceleration (ABA) measurements. We present three case studies. The first one in The Netherlands, the detection of local defects with different severity levels (squat A, squat B and squat C) is analysed. The sec

Smart technology solutions for the NeTIRail-INFRA case study lines
Axle box acceleration and ultra-low cost smartphones
In this paper, we present preliminary results on the development of smart technology solutions for lower density railway lines. The goal is to reach a cost effective inspection and asset management to minimize maintenance
