  1. 6. Rail-air transport competition : A discrete choice analysis along with an international empirical investigation

    University essay from KTH/Transportplanering

    Author : Evgeny Nikolaev; [2022]
    Keywords : ;

    Abstract : There is an increasing interest among many nations to decrease CO2 emissions.Promoting more sustainable modes of transportation is one particular area that has roomfor improvement. For instance, short and medium distance flights can bepotentially substituted by high-speed rail (HSR). READ MORE

  3. 7. 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

  5. 9. 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

  6. 10. Fault diagnosis of axlebox roller bearings of high speed rail vehicles based on empirical mode decomposition and machine learning

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

    Author : JOSUA KEHLENBACH; [2021]
    Keywords : Condition monitoring; axlebox bearings; machine learning; data fusion; Nyckelord: tillståndsövervakning; axelboxlager; maskininlärning; datafusion;

    Abstract : Axlebox bearings are one of the most critical components of a rail vehicle with regard to safety. An axlebox bearing that breaks during operation can be dangerous for the passengers and expensive for the operator. In-service failure of axlebox bearings has been the cause of many catastrophic accidents. READ MORE
