  1. 1. Analysis of combined response of railway bridge and track : A parametric finite element model of the bridge across Bryngeån

    University essay from KTH/Bro- och stålbyggnad

    Author : Moa Nolinder; [2023]
    Keywords : ;

    Abstract : When designing a railway bridge it is common to consider and designthe bridge structure and the track structure separately. However, theyare connected and that interaction generates a combined response and aforce transfer between them. READ MORE

  2. 2. Reinforcement learning for train dispatching : A study on the possibility to use reinforcement learning to optimize train ordering and minimize train delays in disrupted situations, inside the r ail simulator OSRD

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Teodora Popescu; [2022]
    Keywords : ;

    Abstract : Train dispatching is a complex process, especially when the train traffic is disrupted, as the decisions taken by the dispatchers can have substantial consequences on the delays of the trains. The most frequent dispatching decisions consists in changing the order of trains at convergence points, where two tracks unite to become a single track. READ MORE

  3. 3. Detecting Defective Rail Joints on the Swiss Railways with Inception ResNet V2 : Simplifying Predictive Maintenance of Railway Infrastructure

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Anton Lu; [2022]
    Keywords : Rail Defect Detection; Rail Image Classification; Rail Joints; Object Detection; Image Classification; Deep Learning; Järnvägsfeldetektering; Järnvägsbildigenkänning; Järnvägsskarvar; Objectigenkänning; Bildklassificering; Djupinlärning;

    Abstract : Manual investigation of railway infrastructure is a labor-intensive and time-consuming task, and automating it has become a high priority for railway operators to reduce unexpected infrastructure expenditure. In this thesis, we propose a new image classification approach for classifying defect and non-defective rail joints in image data, based on previous fault detection algorithms using object detection.

  4. 4. Återupptagen persontrafik på Västerdalsbanan : en studie av järnvägens betydelse för mobilitet och en fossilfri framtid

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

    Author : Hanna-Louise Aasen; [2021]
    Keywords : mobilitet; järnväg; hållbara transporter; mobility justice; miljömål;

    Abstract : Arbetet undersöker hur befintliga järnvägssträckningar utan persontrafik kan användas och utvecklas för att möta de hållbarhetsmål som är uppsatta av svenska staten och Region Dalarna. Detta görs baserat på en fallstudie som görs kring bandelen Västerdalsbanan (Repbäcken Malung), där områdets historia och förutsättningar ställs mot teorier om mobility justice, hållbara transporter och målsättningar från Region Dalarna, de berörda kommunerna och svenska staten.

  5. 5. 1D LIDAR Speed and Motion for the Internet-of-Things : For Railroad Classification Yards

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Edward Chancellor; Kasper Oikarinen; [2021]
    Keywords : LIDAR; Trains; Internet of Things; Motion-tracking; Rail transportation; Railroad classification yards.; LIDAR; Tåg; Sakernas internet; Rörelsespårning; Tågtrafik; Rangerbangårdar.;

    Abstract : This thesis is an investigation into the feasibility of one-dimensional Light Detection and Ranging (LIDAR) sensors for tracking the position and motion of trains on railroad classification yards. Carefully monitoring railway traffic in these areas is important, in order to avoid accidents, optimise logistical operations and hence reduce delays. READ MORE
