Our personnel have a long experience in the electric railway, safety equipment and superstructure work, as the company’s history dates back to the construction of the first railway electrification in the 1960s under the name Sähköradat Oy. At the beginning of 2017, GRK Infra Oy established Nordic Trackpartners Oy. The name was changed to Winco Oy at the end of 2017. On 31 January 2018, Winco acquired Eltel Networks’ Finnish railway business, and Komsor Oy joined Winco through a business acquisition in late 2018. The name of Winco Oy was changed to GRK Rail Oy on 16 October 2019.
The services cover the design, construction and maintenance services for all technical areas of rail transport. These include the superstructure, the electric tracks, the safety devices as well as special structures. We work in all types of contracts: main contractor and subcontractor, as well as design and build, PPP and alliance models.
GRK Rail Oy’s operating system is certified as a management system in accordance with ISO 9001, ISO 14001 and ISO 45001. We are also RALA-certified. More detailed information on the certificates and qualifications can be found on the website of the Construction Quality Association www.rala.fi. Our operations comply with the Act on the Contractor’s Obligations and Liability when Work is Contracted Out and we require our suppliers to be part of Vastuu Group’s Reliable Partner service.
