Rail infrastructure is a growth industry as many countries are improving their networks and tracks. At the same time, it is a varied business involving a multitude of activities, from basic construction and earthwork to sophisticated signaling work and high-voltage installations. One of the few specialists in this area is Aarsleff Rail A/S. The Danish company does everything related to rail and is benefiting from Denmark’s determination to strengthen public transport and establish a modern high-speed rail network.
