Digital Touch to Rail Transport in Sweden

Sweden is testing a technology that could revolutionize freight transport: Digital Automatic Coupling (DAC) elements. This innovation, which is applied particularly to heavy-duty trains, aims to increase efficiency and ensure safety. The 3.800-ton freight trains used in these tests were equipped with DAC systems from Dellner and Voith. These trains, which carry steel plates on the 1.000-kilometer route from Luleå to Borlänge, serve the Swedish steelmaker SSAB.

Performance Testing in Harsh Conditions

The route features steep gradients, sharp bends and extremely cold weather conditions. These challenging conditions provide an ideal environment to measure the durability and performance of the fasteners. The results of the tests will shed light on Sweden’s ambitions to further develop its railway technology.

The effectiveness of digital connectors is important not only for Sweden, but for all European rail networks. Adopting these systems can reduce delays and improve safety, while increasing operational efficiency.

Real World Testing of Digital Auto Couplings in Sweden

This innovative project is being implemented within the scope of the European Rail Joint Undertaking’s FP5 TRANS4M-R programme. Green Cargo in Sweden is undertaking the project, while Trafikverket is overseeing the train preparations and Rail Sweden is coordinating the test work.

During this two-year research project, different types of wagons and suppliers will participate in the tests. Engineers will collect data to improve performance and evaluate the system’s compliance with international industry standards.

SMP’s test institute provides critical measurements to verify the reliability and durability of equipment. This collaboration highlights the importance of teamwork in developing sustainable transportation technologies.

Impact on the European Railway Network

Successful testing of Digital Auto-Connect systems could lead to rapid adoption of the technology across Europe, meaning less human intervention is needed in rail transport, reducing the risk of accidents and lowering overall costs.

Authorities believe that widespread use of DAC could modernise Europe’s rail networks, making rail transport more competitive with road transport and encouraging environmentally friendly logistics solutions.

Sweden's Leadership in Rail Innovation

By taking on a leading role in rail technology, Sweden is once again demonstrating its commitment to sustainable logistics solutions. The findings from the tests of Digital Auto-Couplers could shape rail transport not only in Sweden but also globally.

This innovative approach aims to both increase efficiency and reduce the carbon footprint of railways. Sweden’s success in this project could serve as an example for other countries and pave the way for smarter and more environmentally friendly transport systems in the future.
