Sibek wins ERTMS commissioning role for greater Malmö
Sweden’s railway signalling consultancy Sibek has been selected to commission ETCS Level 2 across the greater Malmö network — the first deployment of the standard at an urban node in Sweden.
Sibek announced on 28 May that it had been selected by Trafikverket for the assignment. The contract runs from 2026 to 2031, with an option to extend to 2033, and is expected to be one of the largest in the company’s history.
The Malmö node sits at the junction of Sweden’s main north–south corridor and the Øresund crossing into Denmark — making it one of the highest-traffic points in the national ERTMS rollout.
First urban ETCS node in Sweden
Sibek’s role covers the full commissioning process: verifying that safety functions and system interfaces operate correctly before each section is handed over to live traffic. On an urban node, that work runs alongside active operations — trains continue to move while adjacent sections are being verified and cut over in stages.
Malmö handles a dense mix of long-distance, regional and cross-border services. The Øresund Line carries traffic between Sweden and Denmark across the fixed link, and the node connects several of Sweden’s busiest intercity routes. That combination of traffic types and operators sharing the same infrastructure makes interface management the primary engineering challenge.
A different problem from open line
Sweden has deployed ERTMS on open lines since 2010, beginning with Botniabanan. Those projects ran on newly built or lightly trafficked corridors where commissioning could proceed with limited interaction with live services.
Malmö offers no such separation. The interlocking boundaries are dense, the number of operator agreements is higher, and the margin for staged rollout is constrained by timetable dependency across the Øresund corridor.
Sibek has previous experience on Malmbanan, where it worked alongside Omexom, Sweco and Bombardier Transportation on interlocking commissioning ahead of ETCS deployment. The Malmö assignment is a step up in both scale and operational complexity.
Staged delivery through 2031
The contract runs for five years, with Trafikverket holding an option to extend to 2033. Sibek described the project as one of the largest in its history.
No contract value has been disclosed.
