1. 11. 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

3. 12. A comparison of rail and sea freight from Europe to Asia

   University essay from Lunds universitet/Teknisk logistik

   Author : Jackie Berg; Louise Pettersson; [2021]
   Keywords : Sea freight; Rail freight; Transportation mode selection; Asia; Transportation; Technology and Engineering;

   Abstract : Title: A comparison of rail and sea freight from Europe to Asia Authors: Jackie Berg & Louise Pettersson Supervisors: Jan Olhager, Department of Industrial Management and Logistics, Faculty of Engineering, Lund University Malin Gejde, Shipping Manager, Tetra Pak AB Background: Transportation mode selection has become a more strategic part of a well-functioning supply chain as globalization, environmental concerns, and security requirements have become more important. Currently, sea freight is the most used transportation mode for Tetra Pak when transporting goods between Europe and Asia. READ MORE

4. 13. Digitalization in the rail industry: Localizing damaged cargo wagons using spatial operations and big data

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Julia Hellner; [2021]
   Keywords : physical geography and ecosystem analysis; big data; clustering; digitization; geofence; geomatics; GNSS; maintenance; rail; spatial analysis; Technology and Engineering; Earth and Environmental Sciences;

   Abstract : Climate change and the sustainability challenges of the 21st century require the reduction of greenhouse gas emissions in all sectors. Accordingly, political objectives urge for a shift from road to rail in logistics. This drives innovation, increased efficiency, and customer friendliness in the rail industry. READ MORE

5. 14. The Resilience of the Rail System for International Freight in Öresund Region in Case of Major Disruptions

   University essay from KTH/Transportplanering

   Author : Sneha Gosavi; [2021]
   Keywords : Öresund Fixed Link; Capacity constraints; Freight trains; Simulation; Fast förbindelse Öresund; Kapacitetsbegränsningar; godståg; simulering iv;

   Abstract : Rail Transport has held an important place in the European economy. Several problems plague rail freight. We frequently hear about train disruptions, whether it is due to a signal failure or an infrastructure breakdown, most of which have caused significant issues for both passengers and cargo.

6. 15. Investigation of sources of wheel-rail impact force deviation through dynamic simulations

   University essay from KTH/Fordonsdynamik

   Author : Sumanth Ram Aravindababu; [2021]
   Keywords : Multi-body simulations; wheel damages; rail damage; damage thresholds; wheel-rail impact forces; classification; Flerkroppssimulering; hjulskador; rälskador; skadetrösklar; hjulslagkraft; rälslagkraft; klassificering;

   Abstract : Due to the increase in demand on freight transportation it becomes necessary to avoid delays to ensure that the goods reach its destination on time. The main factors causing disturbances in the traffic on the mainline is the breakdown of vehicles mainly due to damaged wheels. READ MORE
