  1. 16. The Effect of High Wheel Impact Load on the Rail Reliability - a Case Study at Bodsjön

    University essay from KTH/Spårfordon

    Author : Ngoc Thúy Vy Dang; [2021]
    Keywords : rail defects; rail reliability; Ultrasonic Test; wheel damage; Wheel Impact Load Detector; statistics; järnvägsdefekter; järnvägssäkerhet; ultraljudstest; hjulskador; hjullastningsdetektor; statistik;

    Abstract : This study focuses on the reliability of railway track in the relation with high loads resulted from wheel damages, where higher (dynamic) vertical wheel loads are expected from trains with damaged wheels. The Swedish Transport Administration (Trafikverket) has monitored and recorded data of rail defects and breaks. READ MORE

  3. 17. RELIABILITY ANALYSIS OF REPAIRABLE SYSTEMS WITH COVARIATES: A CASE STUDY OF RAILWAY TRACK

    University essay from Luleå tekniska universitet/Drift, underhåll och akustik

    Author : Alvaro Andres Rincon Franco; [2021]
    Keywords : Reliability; Railways; Covariates;

    Abstract : Linear assets are complex industrial systems that extend from one geographical region to another. Given the criticality of the industrial activities linked to them, it is vital to accurately estimate the systems' reliability. READ MORE

  4. 18. Life Cycle Cost of Smart Wayside Object Controller

    University essay from KTH/Spårfordon

    Author : Filipp Zarov; [2021]
    Keywords : railway signalling system; interlocking; hardware; Object Controller; Smart Wayside Object controller; Lifecycle Cost; renewable energy sources; järnvägssignalsystem; ställverk; hårdvara; Utdelar; SWOC; livscykelkostnad; förnybara energikällor;

    Abstract : In a regional railway signalling system, object controllers are the devices responsible for controlling Track Side Equipment and act as interfaces for TSE with the interlocking computer and the Traffic control system. However, associated cabling (signal and power cabling) and civil works pose a major capital investment and it is a source of significant Capital and Operational expenses, particularly in rural areas, where accessibility andconnectivity to power grid and to the interlocking are a problem.
