2. 1. Timetable Analysis based on Social Cost and Simulation

   Author : Jennifer Warg; Markus Bohlin; Oskar Fröidh; Carl-William Palmqvist; Paola Pellegrini; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway capacity allocation; timetable analysis; social costs; microscopic railway simulation; macroscopic railway simulation; passengers; timetable performance; early departing freight trains; Järnvägskapacitet; tidtabellsanalys; sociala kostnader; mikroskopisk järnvägssimulering; makroskopisk järnvägssimulering; resande; tidtabellseffektivitet; tidiga godståg; Transportsystem; Transport Systems;

   Abstract : The timetable is essential for railway traffic. Its design affects rail operations – and by extension all operators, passengers, and freight clients. International practice for capacity allocation varies and there is no common algorithm for designing and evaluating timetable changes. READ MORE

4. 2. Punctuality and railway maintenance

   Author : Birre Nyström; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Abstract : Long and frequent train delays, striking many periodically make headlines. The question is raised: what might be done about it? The on-going deregulation of the Swedish railway, with more actors entering the market, contributes to the question's topicality. In this thesis, problems and symptoms concerning punctuality are described and analysed. READ MORE

5. 3. Wayside Condition Monitoring Technologies for Railway Systems

   Author : Matthias Asplund; Ulla Juntti; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

   Abstract : The railway is an important mode of transport, due to its environmental friendliness, high safety level, and low energy consumption, among other reasons. Railways provide a sustainable means of transporting a large amount of freight and passengers, in a cost-effective and comfortable way. READ MORE

6. 4. Dynamic Vehicle-Track Interaction of European Standard Freight Wagons with Link Suspension

   Author : Per-Anders Jönsson; Sebastian Stichel; Evert Andersson; Jerzy Piotrowski; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway; freight wagon; running gear; link suspension; laboratory test; ; stiffness; dry friction; hysteresis; simulation; vehicle-track interaction; multibody; simulation; MBS; Vehicle engineering; Farkostteknik;

   Abstract : The link suspension is the most prevailing suspension system for freight wagons in Central and Western Europe. The system design is simple and has existed for more than 100 years. However, still its characteristics are not fully understood. READ MORE

7. 5. Train Based Automated Inspection for Railway Fastening System

   Author : Praneeth Chandran; Matti Rantatalo; Rolf Dollevoet; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rail fastening system; clamps; visual inspection; differential eddy current sensor; machine learning; anomaly detection; Drift och underhållsteknik; Operation and Maintenance;

   Abstract : Rail transportation is a sustainable mode of transportation and is a key enabler of the socio-economic development of modern society through passenger and freight services. Growth in overall transport demand has led to railways experiencing higher demand on operational capacity, service quality, and safety. READ MORE
