The German producer of special lubricants, Lubricant Consult GmbH, has been approved by the German railway organization (Deutsche Bahn) for several years. In 2014 the special grease Sintono Terra SK RE 1 received approval of Rete Ferroviara Italiana (RFI), the Italian railway. Having completed several trials successfully, the biologically degradable grease can now be applied by RFI.
