1. 21. The Effect of High Wheel Impact Load on the Rail Reliability - a Case Study at Bodsjön

   University essay from KTH/Spårfordon

   Author : Ngoc Thúy Vy Dang; [2021]
   Keywords : rail defects; rail reliability; Ultrasonic Test; wheel damage; Wheel Impact Load Detector; statistics; järnvägsdefekter; järnvägssäkerhet; ultraljudstest; hjulskador; hjullastningsdetektor; statistik;

   Abstract : This study focuses on the reliability of railway track in the relation with high loads resulted from wheel damages, where higher (dynamic) vertical wheel loads are expected from trains with damaged wheels. The Swedish Transport Administration (Trafikverket) has monitored and recorded data of rail defects and breaks. READ MORE

3. 22. 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.

4. 23. Energy Harvesting for Health Monitoring Balises : Analytical study

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

   Author : Leire Carreras Orobengoa; [2021]
   Keywords : Balise; Energy harvesting; Railway signaling; Wireless communication networks;

   Abstract : Balises are transponders installed in railways. These devices are nowadays powered by means of a radiofrequency signal emitted by each running train that passes above them. It is only during this moment that the health state of the balises is checked. READ MORE

5. 24. 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.

6. 25. 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.
