21. 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 stålbyggnadAbstract : 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

22. Estimating the Values of Missing Data in Railway Networks Using their Spatial Correlation
University essay from KTH/TransportplaneringAbstract : In railway infrastructure management, it is always desired to know the conditionof each track segment, which is represented approximately by the conditionindicators. The values of condition indicators can be used as a decisioncriterion about whether the intervention on the track should be implementedin the future or when the intervention should be executed.

23. Artificial Intelligence applications for railway signalling
University essay from KTH/TransportplaneringAbstract : 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.

25. Strategic passenger-oriented timetable design : Long-term timetable designs with minimised passenger inconvenience
University essay from KTH/TransportplaneringAbstract : 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.
