Smart technology solutions for the NeTIRail-INFRA case study lines: Axle box acceleration and ultra-low cost smartphones

Abstract

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
interventions time/cost without dedicated inspection vehicles. The proposed methods include axle box
acceleration measurements and ultra-low cost smartphones. The collected data will be further used to increase
knowledge of the condition of the railway track and to estimate the comfort of passengers. In order to make use
of the data, the data is interpreted and converted from monitoring information into management information.
Feasibility and preliminary studies were conducted in the railway lines of Romania. The results presented in this
paper were obtained in the framework of the H2020 project NeTIRail-INFRA, Work Package 4: Monitoring and
Smart Technology.
