2. 1. Railway traffic disturbance management

   Author : Johanna Törnquist; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Railway traffic; Transportation; Re-scheduling; Disturbance management; Decision support systems;

   Abstract : With the increasing traffic volumes in many railway networks and reports on capacity deficiencies that result in insufficient punctuality and reliability, the need for efficient disturbance management solutions becomes evident. This thesis focuses on solutions that aim to minimise the consequences of disturbances for the various stakeholders and specifically on methods for re-scheduling the traffic. READ MORE

4. 2. Leveraging Data-Driven and Alignment Techniques for Optimal Railway Track Maintenance Scheduling

   Author : Mahdi Khosravi; Alireza Ahmadi; Uday Kumar; Iman Soleimanmeigouni; Anders Ekberg; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway tracks; degradation; maintenance; tamping; track geometry; planning and scheduling; alignment; Operation and Maintenance Engineering; Drift och underhållsteknik;

   Abstract : The railway infrastructure plays a pivotal role in fostering economic growth and poverty alleviation. Over time, these infrastructures deteriorate due to aging and usage, compromising their functionality. Given their crucial socioeconomic significance and vast scale, ensuring their functionality and availability is paramount. READ MORE

5. 3. Data-driven models for railway track geometry maintenance

   Author : Hamid Khajehei; Alireza Ahmadi; John Andrews; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data-driven models; degradation; maintenance; tamping; track geometry; planning and scheduling; railway infrastructure; Drift och underhållsteknik; Operation and Maintenance;

   Abstract : Railways are currently experiencing higher demands on safety, infrastructure performance, network capacity and service quality, etc. As a result, a high level of track availability, service quality and infrastructure robustness against unexpected events is required, at reduced cost, to meet the demands.

6. 4. Computer-based decision support for handling uncertainty in railway traffic and transportation

   Author : Johanna Törnquist; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Railway scheduling; train traffic; transportation; agent systems;

   Abstract : Railway transportation has great potential, but interdependencies in the railway traffic make trains very sensitive to disturbances, which can bedifficult to handle. Using railway in an intermodal transport chain may complicate the interconnections with other modes if there is large uncertainty in the performance of the railway. READ MORE

7. 5. Efficiency of the trackwork scheduling process in Sweden

   Author : Daria Ivina; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railways; Maintenance management; Trackwork scheduling; Project Uncertainties; Lean; Efficiency;

   Abstract : Efficient scheduling is vital for railway maintenance, which is increasingly challenged by rising train traffic and infrastructure wear. Trackwork often necessitates the reduction of train speeds and the partial or complete closure of tracks. READ MORE
