  1. 1. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Erik Nordlund; [2023]
    Keywords : Inductive switch point heating; Turnout heating; railway turnout heating; Inductive heating;

    Abstract : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance.

  2. 2. Challenges in the Maintenance and Diagnostic Segment of Digital Asset Management in the Swedish Railway Industry

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Salam Adeeb; Marwan Ouali; [2023]
    Keywords : Railway Digital Asset Management; remote monitoring; condition-based maintenance; predictive maintenance; Digital tillgångsförvaltning; prediktivt underhåll; tillståndsbaserat underhåll; diagnostik;

    Abstract : Just like the rest of society, the use of digital technology has throughout the years become a more crucial part for train companies to improve performance, meet customer demands, improve operation and maintenance processes to increase efficiency and reliability. These solutions have through time developed to become part of a cluster named Digital Asset Management (DAM). READ MORE

  3. 3. Data Augmentations for Improving Vision-Based Damage Detection : in Land Transport Infrastructure

    University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Author : Punnawat Siripatthiti; [2023]
    Keywords : Computer Vision; Data Augmentation; Object Detection; Crack Detection; Road Damage Detection; Sleeper Defect Detection; datorseende; dataökning; objektdetektering; sprickdetektering; vägbeläggning; järnvägsslipers;

    Abstract : Crack, a typical term most people know, is a common form of distress or damage in road pavements and railway sleepers. It poses significant challenges to their structural integrity, safety, and longevity. Over the years, researchers have developed various data-driven technologies for image-based crack detection in road and sleeper applications. READ MORE

  4. 4. Predicting Short-term Absences of a Railway Crew using Historical Data

    University essay from KTH/Matematisk statistik

    Author : Agnes Björnfot; Sandra Fjelkestam; [2023]
    Keywords : statistics; machine learning; absence prediction; random forest; XGBoost; quantile regression; statistik; maskininlärning; frånvaroprognoser; random forest; XGBoost; kvantilregression;

    Abstract : Transportation via train is considered the most environmentally friendly way of traveling and is widely seen as the future of transportation. Canceled and delayed trains worsen customer satisfaction; thus, punctual trains are crucial for railway companies. READ MORE

  5. 5. Anomaly Vibration Classification for Condition Monitoring in Passenger Cars

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Rui Zhou; [2023]
    Keywords : ;

    Abstract : This research aims to investigate accurate classification of anomalous vibrations produced during vehicle operation. The main research questions are which data can be used as classification criteria, which models can better achieve classification effects, and how to address classification issues under different variables in a car.
