They went for the easy target. Railroad is a separate issue, with separate financing and economics to the actual mining operation. KWG has all that stuff in charge of their subsidiary, Canada Chrome, and also does not actually have any 'railway rights', just mineral rights along the most feasible route.
Some time down the line we might even see ore being shipped on CC's railway, but not from our deposit. We'd get the 1% NSR regardless, as well as RR revenue.
