Running resistance modelling of freight trains
Background
In light of higher energy costs and new legislation demanding large energy consumers to be more energy efficient, reducing our energy consumption is a priority. An important step is to better understand the running resistance of individual trains and vehicles and its contribution to energy consumption. Combining the energy consumption data recorded by the on-board systems alongside train and track data can help us to model the running resistance for each vehicle in the train as a function of track geometry, vehicle mass, train speed, running dynamics of the vehicle, and other relevant factors. A detailed breakdown of energy consumption and a robust running resistance model can be useful to Green Cargo in several ways; guide in future vehicle acquisition, evaluating the impact on on-going energy-improving initiatives, and helping prioritise future improve energy efficiency efforts.
Problem description, tasks and goals
Use available large datasets to estimate each vehicle contribution to the total running resistance of the train under different operating conditions and circumstances.

Om företaget
Green Cargo is Sweden’s most experienced operator in rail logistics with roots in the origins of Swedish rail traffic. We deliver sustainable logistics solutions and are an important part of Scandinavia’s trade and industry. In 2025, our transport performance amounted to 8.6 billion net tonne-kilometres. Nearly 98 percent of our total transport work was carried out using electric locomotives powered by fossil-free electricity. Every weekday, we move 31 million net tonne-kilometres of goods, helping to remove approximately 9,000 truck journeys from the road network.
With 1,600 employees and annual revenue of SEK 4.0 billion (2025), Green Cargo is a key contributor to a more sustainable and efficient transport system.
Visste du att..TOM
TOMDygnet runt transporterar våra godståg råvaror från skogar och gruvor till processindustrins anläggningar och konsumentvaror till detaljhandeln. Logistiksystemet lägger grunden för Sveriges välstånd och konkurrenskraft.
TOMJärnvägstransporter är det mest yt- och energieffektiva och minst miljöbelastande trafikslaget. Varje dygn kör våra lokförare 350 godståg som ersätter i genomsnitt 9000 lastbilar.
TOMEn transport av 23 ton gods med Green Cargos eltåg mellan Malmö kombi och Norrköping kombi (442 km) släpper ut ungefär 1 kilo CO2e med fossilfri el. Om samma mängd gods transporteras med tung lastbil, skulle utsläppen vara cirka 560 kilo CO2e.
TOMGreen Cargos totala transportarbete 2024 (eltåg, dieseltåg och lastbil) gav ett sammanlagt utsläpp på 17 273 ton koldioxid (CO2e). Vårt totala transportarbete uppgick till 9,7 miljarder nettotonkilometer. Om allt gods som Green Cargo transporterade istället hade körts med lastbil hade utsläppet blivit 512 000 ton koldioxid (CO2e).
