About our history

AB Infra Polar, established in Sweden in 2012 by GRK Infra Oy and Ab Tallqvist Oy, changed its name to GRK Infra AB in July 2018, when GRK Infra Oy acquired the company entirely.

The history of GRK Rail dates back to 1969 when Sähköradat Oy started the construction of the first rail electrifications in Finland. GRK acquired the track business in Finland in 2017 and decided to expand the business to the Swedish market in 2020 thus estalishing GRK Rail AB.

Until the beginning of 2023, GRK Infra AB and GRK Rail AB operated as separate companies in Sweden. With the changes in the organizational structure and the development of the operating model implemented in all GRK Group countries, the companies were merged into GRK Sverige AB.
