Strukton already provides infrastructure maintenance services on these lines, but under the new contract it will assume overall responsibility for maintenance of signalling systems, power supply, and track. Strukton will also take over several functions previously managed by SL, including infrastructure inspection, long-term investment and maintenance planning, and monitoring of some CCTV systems. A number of SL employees will transfer to Strukton under the new arrangements.

The new contracts will run for a minimum of five years from 2013, and the deal will be worth SKr 3bn ($US 427m) if SL exercises options to extend the term to nine years.
