The contract is for a term of four years during which Alstom will maintain 26 Alstom-made Metropolis trains, as well as traction substations and signaling systems.
Unlike classic signalling systems, it is capable of determining the exact position of each train on the line thanks to its state-of-the-art on-board control units.
LEROY Automation offers field-bus communication gateways specifically designed for the railway market in order to interconnect these types of equipment while respecting the required levels of requirements.
Available with single or dual output, these DC-DC Converters are specifically designed for railway applications, providing even greater flexibility and efficiency.
The maintenance will start in December 2025 and will be carried out in Umeå and Luleå, increasing the presence of Alstom’s operations in the north of Sweden.
The shunters, which are owned by Porterbrook, are expected to reduce emissions by 40% and will be used to move steel billets from an electric arc furnace to CELSA’s rolling mills.
