We test tracks using state-of-the-art methods. We provide quality assurance by inspec­ting track super­s­truc­ture works accor­ding to current standards. Our exper­tise and experi­ence are now in demand inter­na­tio­nally – not least because preven­tive track mainten­ance saves costs in the long term and makes environ­men­tally friendly rail and light rail trans­port systems safe and comfor­ta­ble.
