About Aarsleff Rail A/S
Tracing its industry heritage back to 1911 through rail pioneer Petri & Haugsted, Aarsleff Rail A/S was formalized in 2009 by uniting the specialized railway construction activities of the Per Aarsleff Group. Headquartered in Viby J (Aarhus), Denmark, Aarsleff Rail operates as an independent railway infrastructure contractor with operating subsidiaries across Sweden (Aarsleff Rail AB) and Norway (Aarsleff Rail AS).
The company covers the complete railway engineering lifecycle across mainline, high-speed, commuter (S-bane), and light rail systems. Aarsleff Rail operates a large in-house fleet of specialized heavy yellow machines—including mechanized track-laying gantries, ballast tampers, ballast regulators, flash-butt welding equipment, and rail-road excavators.
Aarsleff Rail serves as a trusted framework contractor for national railway administrations, including Banedanmark in Denmark, Trafikverket in Sweden, and Bane NOR in Norway. Its project portfolio encompasses high-output track renewals, continuous welded rail (CWR) installations, level-crossing modernizations, ETCS Level 2 wayside signaling installations, overhead contact system (OCS) electrification, and light rail line constructions (such as the Odense Letbane and Hovedstadens Letbane in Greater Copenhagen).
