KTH and Alstom in joint effort for a sustainable European railway system

Sweden’s largest technical university, KTH Royal Institute of Technology, is collaborating closely with Alstom to further develop train traffic in Europe as part of Europe’s Rail Joint Undertaking (EU-Rail) to develop a sustainable and efficient rail network throughout Europe.

The EU is focusing heavily on sustainable travel. With Europe’s Rail Joint Undertaking (EU-Rail), the vision is to introduce a high-capacity, highly reliable integrated European railway system to reduce climate impact and meet increased transportation needs.

In May 2022, KTH begun a strategic partnership with mobility solutions provider Alstom, and alongside the Swedish Transport Administration they are bringing research funding and innovation to the EU initiative.

The goal of EU-Rail is to increase the use of railways to transport passengers and freight, and to reduce greenhouse gas emissions. In partnership with the Swedish Transport Administration and Alstom, KTH is contributing solutions and boosting the geographical and transport-related conditions and regulations in the Swedish railway system.

“The major problems with Europe’s rail transport primarily relate to a lack of capacity due to underinvestment in the infrastructure. There are also different technical systems and regulations in the various countries. This could mean that a train approved in Sweden is not allowed to run in Denmark,” says Sebastian Stichel, professor in rail vehicle dynamics at KTH and a former employee of Alstom.

There are currently six flagship projects in EU-Rail, with grants of up to SEK 500 million and up to around 50 partners per project. The projects began around the new year, will run for four years, and relate to everything from innovation of signaling systems to allow more frequent services, to finding more eco-friendly alternatives to diesel-powered trains, such as battery- or hydrogen-powered trains. KTH is taking part in all six projects, including the one being headed up by Alstom which relates to environmental issues and energy consumption.

“It’s important to move transport to the railway to reduce climate impact. We want to contribute innovation so that trains are more eco-friendly and make it cheaper and easier to travel by train,” added Stichel.

Four KTH schools are taking part (Architecture and the Built Environment, Electrical Engineering and Computer Science, Engineering Sciences, Industrial Engineering and Management) and the grants focus on everything from digitalization solutions, techno-economic studies, driverless trains, and improved safety at level crossings, to new mechanical solutions to reduce costs and weight for rolling stock.

Driverless trains are one particular area where KTH is contributing a lot of research. It is a prioritized area which, in combination with effective signaling systems, will enable more frequent train services with greater capacity.

Since May 2022, KTH has had a strategic partnership with Alstom, the biggest rolling stock manufacturer on the Swedish railway market. The partnership involves close collaboration to secure skills in the sector, as well as development-oriented research that is of benefit to society.

Collaboration on Green Train project

Collaboration on the EU-Rail projects is pivotal, but KTH has been working with Alstom in Sweden for a long time. For instance, they worked together on the Gröna Tåget/Green Train project, with KTH helping to develop a new type of motor for electric trains. The motors are now in use on Alstom’s trains.

“We enjoy a hugely beneficial interchange. Alstom has a lot of influence in the rail industry, and if they’re doing well there’s a greater chance that students will want to study railway engineering here at KTH. Our partnership will also bolster KTH’s transport research and bring a Swedish perspective and Swedish technology to EU-Rail,” noted Stichel.

Fredric Bonnevier, head of DC performance at Alstom Sweden, agreed and stressed how important the research partnership with KTH is to Alstom. “It enables us to collaborate on joint projects, not only in national societal development but also internationally through technological development and issues related to railways, rolling stock, and signaling systems. The partnership is also of strategic importance to our operation regarding skills supply, skills development, and research,” he added. 

EU-Rail – the facts

EU-Rail, Europe’s Rail Joint Undertaking, went ahead in late 2021 and is part of Horizon Europe, the EU’s framework program for research and innovation 2021-2027. To date six projects have been awarded grants. Starting around the new year and running for four years, there is also a call for further initiatives.

The aim of the program is to create an integrated, high-capacity European railway system by contributing solutions and innovations for rolling stock, infrastructure and services. Ultimately, the initiative aims to contribute to the European Commission’s strategy for a sustainable and smart transport sector.

The program builds on the results of the previous initiative, Shift2Rail, and the primary goals relate to digitalization and automation of railway systems to enable a sustainable, environmentally friendly transport sector for passengers and freight.
