In this changeset you have created a railway "superroute" that meanwhile has grown to over 18k members. Is this really an observable, verifiable object that deserves to be in OSM? You describe it as a "corridor" but what has been mapped is a very precise line of meanwhile over 18.000 pieces of railway track. Frankly I think that it should be deleted & I will post on the community forum about it to involve more community members in the discussion.
