STOCKHOLM, Dec. 22, 2025 /PRNewswire/ — EQT is pleased to announce that the EQT Active Core Infrastructure I fund (“EQT”) has agreed to acquire 100% of A-Train AB (“A-Train” or the “Company”), the operator of the Arlanda express high-speed rail service, from its current shareholders.

Arlanda express is Sweden’s flagship high-speed airport rail service, connecting Greater Stockholm – home to approximately 2.5 million people – with Arlanda Airport in just 18 minutes.
