SWEDEN, March 2026 — The ongoing drive for automation and improved safety in rail logistics is pushing the adoption of advanced technologies. Digital Automatic Couplers (DAC) represent a critical innovation aimed at streamlining operations and enhancing the reliability of freight trains.
SHN Cargo, in collaboration with the Swedish Transport Administration (Trafikverket), has successfully completed a two-year trial of DAC technology. The tests were conducted on an intermodal train operating between Nässjö and the Port of Gothenburg, focusing on mechanical performance, wear, and operational safety under real-world conditions.
This trial is notable as it represents the first deployment of DAC in commercial operation within Europe. The positive technical results and operational experience gained by SHN Cargo suggest a promising future for DAC integration into broader European rail networks, potentially leading to increased efficiency and reduced downtime.
The initiative was undertaken as part of the TRANS4M-R project, supported by Europe’s Rail Joint Undertaking. This collaborative effort underscores a commitment to advancing rail technology through rigorous testing and validation in commercial environments, moving beyond theoretical applications.
The successful conclusion of this DAC trial aligns with global trends towards greater automation and digitalization in the transport sector. As the industry seeks to improve sustainability and operational resilience, technologies like DAC are poised to play an increasingly vital role in the evolution of rail freight.
