In defense of the SLRG (who needs none, in my opinion), there have been a few plans that should have worked, but either the interchanging RR's or the locals when berserk and squashed the whole thing. Out on the South Fork Branch, plans were afoot to load coal at Hanna, between Del Norte and South Fork. The mine south of Hesperus is trucking coal down to the BNSF in Gallup for shipment (to export in Houston - I think). The mining company wanted to truck the coal to Hanna and load it there. It would cut the distance to be trucked as well as the rail mileage. The BNSF wanted nothing to do with it. They would lose a money on the deal, so they flatly refused play ball. The plan was revisited when a new cement plant was opened out of Pueblo. Again the BNSF refused to play. La Plata Coal ship coal to the plant by way of Gallup and Amarillo.
There was another plan to do an environmental cleanup in Los Alamos. The dirty dirt would be trucked to Antonito, and loaded into special gondolas for transfer to the facility in SE New Mexico. The operation would have created several jobs in Antonito. But the Tonyville Loonies went berserk about the "terrible radio-active, glowing in the dark, pile of dirt" that would be down south of town and filed an injunction with the local courts. The clean up crew decided it was not worth fighting for. Now the dirt comes through town on trucks....
FYI, the dirt would have been entirely containerized.
