1. 16. Shielding of Transformer Stray Fields in Trains

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

   Author : Lárusdóttir Lára Ólafia; [2022]
   Keywords : ;

   Abstract : Generally, a transformer will produce stray magnetic fields. Aboard trains, the transformer’s stray fields can pose problems to other components inside or outside the train. Further, regulations require the magnetic field to be below certain levels in the passenger area. READ MORE

3. 17. The Attention of Train Drivers : An experimental study of differences in attention between Automatic Train Control and European Railway Traffic Management System (ERTMS)

   University essay from Linköpings universitet/Filosofiska fakulteten; Linköpings universitet/Interaktiva och kognitiva system

   Author : Lisa Bernheim; [2022]
   Keywords : The Swedish National Road and Transport Research Institute; ERTMS; visual attention; situation awareness; eye-tracking; Statens väg- och transportforskningsinstitut; ERTMS; visuell uppmärksamhet; situation awareness; eye-tracking;

   Abstract : A European project is gradually replacing the current train control systems to a mutual control system called as the European Railway Traffic Management System (ERTMS). I Sweden they have implemented the new train control system on a few train-lines in the northern part of Sweden. READ MORE

4. 18. 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.

5. 19. Analysis of Positional Precision when Using Ground Control Points with Supported INS in GNSS-Free Environments

   University essay from KTH/Fastigheter och byggande

   Author : Linus Bäckström; Patrik Grenert; [2021]
   Keywords : Track maintenance; GNSS; INS; GCP; GNSS-free environments; Railway positioning; Rälsunderhåll; GNSS; INS; Kända punkter; Avsaknad av GNSS; Positionering på räls;

   Abstract : Railway traffic is one of the most used transportation methods in today's society both for freight transports and transportation of people. A necessity for this to function is that the tracks upon which the trains travel are functional. READ MORE

6. 20. 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
