If we look at different language labels, partly main topic of this portal is railway (Q22667), partly is rail transport (Q3565868), partly is unknown item. But I suppose that all topics are closely related, so we don't want to separate this item (solely because of labelling). Should we add this case to exclusions (for "single constraint")? --Infovarius (talk) 13:46, 17 February 2015 (UTC)
