  1. 1. Holistic embedding of equivalent conicity in wheelset maintenance

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Philipp Linzbichler; [2023]
    Keywords : Railway Operation; Equivalent Conicity; Wheelset Maintenance; Smart Maintenance; Data Analysis; Järnvägsdrift; Ekvivalent Konicitet; Hjulset Underhåll; Smart Underhåll; Dataanalys;

    Abstract : With continuing digitization of railways an increasing number of data is recorded but particularly in operation advanced analysis tends to be partially rudimentary. Yet, it is essential to implement sophisticated processing for all records in order to develop more purposeful and predictive vehicle maintenance strategies that adhere to the increasing requirements imposed by the homologation.

  3. 2. Optimization of the Onboard Computer

    University essay from KTH/Matematik (Avd.)

    Author : Alexej Filinau; [2022]
    Keywords : ;

    Abstract : As the population is growing, the need for sustainable and safe mobility solutions increases. The evolution of technology within the railway industry is crucial for a more connected world. Hence, it is important to potimize the Automatic Train Protection, ATP, to ensure that high-speed trains remain fast and safe. READ MORE

  4. 3. Parametric Studies of Train-Track-Bridge Interaction : An evaluation of the dynamic amplification due to track irregularities for freight transport

    University essay from KTH/Bro- och stålbyggnad

    Author : Rasmus Elm Dahlman; Emil Lundberg; [2021]
    Keywords : Dynamics; dynamic amplification factor; railway bridge; train-track-bridge interaction; vehicle model; track irregularities; PSD; Dynamisk förstoringsfaktor; dynamik; järnvägsbroar; tåg-spår-bro interaktion; fordonsmodell; spårojämnheter; PSD;

    Abstract : In this thesis a train-track-bridge interaction (TTBI) model is developed in order to study the dynamic amplification from track irregularities on railway bridges traversed by freight trains. These simulations are of great importance since rail freight transport is expected to increase in order to meet the climate goals. READ MORE

  5. 4. A novel way of building high-speed railways with optimised overhead wire lengths

    University essay from KTH/Matematisk statistik

    Author : Axel Backlund; [2021]
    Keywords : High-speed railways; dynamic programming; optimization; Höghastighetsjärnväg; dynamisk programmering; optimering;

    Abstract : High-speed railways provide fast, comfortable and environmentally friendly transportation for passengers. However, they are fraught with high investment costs that decrease the willingness of governments to construct new lines. READ MORE

  6. 5. Infrastrukturens framfart i rekreations- och friluftslivslandskapet : förutsättningar och potential för rekreations- och friluftslivsvärden i infrastrukturprojekt inom transportsektorn

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Cecilia Smedbro; [2020]
    Keywords : friluftsliv; rekreation; infrastrukturprojekt; järnväg; väg; höghastighetståg; juridiska förutsättningar; potential; förutsättningar;

    Abstract : I takt med att samhället expanderar så sker utbyggnad av vårt infrastrukturnät. Sverige står inför stora infrastruktursatsningar, inom bland annat järnväg, som inte varit aktuellt på 150 år. Transportinfrastruktur med dess anläggningar innebär stor påverkan på landskapet. READ MORE
