Alstom has completed the modernisation and upgrade of 270 models C20 metro cars for Stockholm, a project initiated in 2017. The last car left the workshop in Västerås to return to Stockholm, fully prepared for passenger service.
The modernisation programme emphasises the extensive reuse of materials to achieve environmental and cost-saving benefits. Additionally, the interior layout has been updated with an open design and new seating arrangements, facilitating quicker boarding and disembarking, and new passenger information systems, enhancing the passenger experience.
“For our operations in Västerås and for our local subcontractors, this project has been of significant importance, placing the Västerås workshop on the map internationally showing our expertise in the domain,” Maria Signal Martebo, Managing Director of Alstom in Sweden, said.
The project was carried out in close collaboration with Alstom’s customer MTR and the end customer SL.
The project to modernise 270 models C20 metro cars has been in progress since 2017, employing 110 fitters and 25 engineers, along with several local subcontractors in Västerås. The upgrade includes the reuse of materials, refurbished seats, new passenger information systems, more handrails, and more safety cameras than before. The new open design facilitates boarding and disembarking. In total, 27,540 seats have been installed, 110,160 screws used, and 240 kilometres of cable laid.
Since 2020, Stockholm Metro received Movia C30 metro trains manufactured by Alstom and are replacing progressively the old rolling stock. The four-car train has a driver’s cab at each end. Each train has a seating capacity reaches 140 passengers in four-by-four configuration with additional seats along the vehicles’ sides, as well as standing areas and multi-purpose spaces to optimise comfort, capacity and passenger flow.
Stockholm is currently expanding its metro system covering the extension of Blue Line from Akalla to Barkarby with two new stations expected to enter operation in 2026. The Blue Line will also be further extended with six stations from Kungsträdgården to Södermalm, Söderort and Nacka which will enter service in 2030. The Green Line is also extended with three stations from Odenplan to Arenastaden. This section is expected to be operational from 2028
