  1. 6. Artificial Intelligence applications for railway signalling

    University essay from KTH/Transportplanering

    Author : Benjamin Smakic; [2021]
    Keywords : Artificial Intelligence; AI; Machine Learning; ML; Computer Vision; railway signalling; ERTMS level 3; GPS; autonomous train operations; Artificiell Intelligens; Maskininlärning; datorseende; signalteknik; autonoma tåg; självkörande tåg.;

    Abstract : The main purpose of this Master Thesis is to investigate how front-facing, train-mounted cameras and Computer Vision, a type of Artificial Intelligence (AI), can be used to compensate for GPS inaccuracies. By using footage from track-recording cameras, Computer Vision can be utilized to determine the number of tracks and the track occupancy of the train, which would compensate GPS inaccuracies in the lateral positioning.

  3. 7. Strategic passenger-oriented timetable design : Long-term timetable designs with minimised passenger inconvenience

    University essay from KTH/Transportplanering

    Author : Yari de Graaf; [2021]
    Keywords : ;

    Abstract : Timetable development and design is a complex process that is crucial for safe and efficient railway operations. The combination of steel wheels and steel rails makes it possible to create trains and to transport many vehicles, thus passengers and freight, at the same time, but it also results in longer braking distances.

  4. 8. A Digital Test Bench for Pneumatic Brakes

    University essay from KTH/Spårfordon

    Author : Bastian Schick; [2021]
    Keywords : Compressed air brake; Freight train; Modular simulation; Pneumatics; Railways; System modelling; Tryckluftsbroms; Godståg; Modulär Simulering; Pneumatik; Järnväg; Systemmodellering;

    Abstract : This master’s thesis covers the structuring and implementation of a digital testbench for the air brake system of freight trains. The test bench will serveto further improve the existing brake models at Transrail Sweden AB. Theseare used for the optimised calculation of train speed profiles by the DriverAdvisory System CATO.

  6. 10. Monitoring energy efficiency of heavy haul freight trains with energy meter data

    University essay from KTH/Spårfordon

    Author : Philipp Geiberger; [2021]
    Keywords : Energy consumption; Energy meter; Energy monitoring; Heavy haul freight train; Key performance indicator; Multi-particle model; Simulation; Energiförbrukning; Elmätare; Energiuppföljning; Tungt godståg; Nyckeltal; Flerpartikelmodell; Simulering;

    Abstract : In this MSc thesis, it is investigated what parameters are relevant for describing energy consumption of heavy haul freight trains and how these can be used to develop key performance indicators (KPIs) for energy efficiency. The possible set of KPI is bounded by data available from energy meters used in electric IORE class locomotives hauling iron ore trains in northern Sweden. READ MORE
