These things are complicated. I know a busy lumber yard that recently rebuilt its siding in expectation of continuing rail service, only to have the railway offer a container based, truck delivered service at a price they couldn't decline. The back story being, the railway had an ongoing need to backhaul empty containers on the same line. By filling them with lumber, they could derive revenue from the backhaul, while sharing the savings (no bulkhead flat car utilization) with the customer.
Maybe if the container flow changes, they will go back to carload deliveries.
