1. 1. Estimating the load weight of freight trains using machine learning

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

   Author : Erik Kongpachith; [2023]
   Keywords : Railway freight Transport; Rail Vehicle Weighing; Y25 Bogie; Sdggmrss T3000eD; GENSYS; Machine Learning; Regression; Polynomial Regression; Regression Trees; Random Forest Regression; Support Vector Regression; Järnvägsgods transport; Vägning av järnvägsfordon; Y25 Bogie; Sdggmrss T3000eD; GENSYS; Maskininlärning; Regression; Polynom Regression; Regressionsträd; Random Forest Regression; Support Vector Regression;

   Abstract : Accurate estimation of the load weight of freight trains is crucial for ensuring safe, efficient and sustainable rail freight transports. Traditional methods for estimating load weight often suffer from limitations in accuracy and efficiency. READ MORE

3. 2. Improved Bridge Load Capacity via Dynamic Train-Track-Bridge Interaction : Assessing the dynamic amplification factor caused by measured track irregularities for rail freight transport

   University essay from KTH/Bro- och stålbyggnad

   Author : Muhannad Asaad; [2023]
   Keywords : ;

   Abstract : The carbon impact of transportation is large and requires sustainable solutions. With expected population growth, rail transportation plays a vital role in facilitating a greener Europe. The expansion of the rail infrastructure is therefore of essential importance for future challenges. READ MORE

4. 3. Evaluation of two different transport options for freight of heavy battery cells : a case study

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Malin Andersson; Sara Fridhagen; [2022]
   Keywords : supply chain; sustainability; Lean; battery electric vehicle; transport; filling rate; truck; train; dangerous goods; tied-up capital;

   Abstract : With the change that is taking place in the automotive industry, where production goes from producing internal combustion motor vehicles (ICE) to battery electric vehicles (BEV), this will lead to an increase in transportation of batteries. Batteries are components that are heavy, expensive, and classified as dangerous goods, which means higher demands on transport. READ MORE

5. 4. Cost Efficient Scrap Metal Sourcing

   University essay from Lunds universitet/Teknisk logistik

   Author : Sophia Sandström; Sofia Ivarsson; [2022]
   Keywords : Scrap sourcing; Scrap logistics; European scrap market; Sea freight strategies; Bulk shipping; Technology and Engineering;

   Abstract : The steel industry in Sweden is responsible for 10% of the annual Swedish CO2 emissions. As a way to abate this sector, H2 Green Steel are establishing a new green steel production site in Boden. Their way of producing steel, through the EAF route and by using hydrogen-reduced DRI will reduce the CO2 emissions by over 90%. READ MORE

6. 5. 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
