The Group

CLF is born from a long history of engagement “on the tracks”. A history that continues thanks to the will of the Dutch shareholder Strukton Rail that, strongly oriented to development and innovation provides “full service” solutions in the railway infrastructures, rail machinery and mobility systems in general.
