and interlocking


Aarsleff Rail has extensive experience in working with signalling and interlocking as well as related high-voltage power projects. We have solved tasks throughout the country both in main contracts and as subcontractors. On all projects, our broad knowledge of many different types of installations has been valuable to the customer and business partners.

We have company authorization in accordance with the Danish high-voltage regulation and approval to carry out all types of electrical work at Banedanmark's facilities. Our team on any given assignment is assembled for the task and often includes both signalling and high-voltage capabilities. This gives the customer a better and more profitable solution to the project.

We perform:

• wiring and connecting cables in relay cabins
• installation of electrical point motors
• wiring and mounting cables for signals and points
• installation of insulated rail joints and axle counters
• remote control installation
• testing and commissioning.


At track renewals we dismantle signalling and interlocking components (balises and HKT-elements) before track work begins and re-establish everything again and then perform documentation, testing and commissioning in advance of a reopening of the renewed line. In addition, we rebuild control panels when a track layout is modified, making sure the new track layout can be managed safely. At track renewals we also perform cable search and repair cables in case of damage.


Aarsleff Rail has approved personnel for testing and commissioning of all types of interlocking systems:

• commissioning supervisor
• testing manager
• commissioning manager
• switchover manager.
