Standard Metals in Silverton shipped most of their ore concentrates from Ridgway all during the 60s and up to abandonment. They then had to truck into Montrose for rail shipment up to mine closure in 1991. At other times, large quantities of iron oxide was shipped from Ridgway. I doubt much if any coal came in as the mines at Paonia are too close by truck.
When I was in Montrose last week, there were large outgoing shipments of wood chips being loaded at the old ore loading dock, and there were a number of incoming loads of lumber. I was surprised by how much rail activity I saw there.
