Ridgway still had a local serving it when I went to School in Grand Junction in 1970-72. The line never hauled much, an occasional car of coal inbound but I have no idea about outbound.
Of course, when I visited there, the RGS caboose was still lettered MK&T and all of the storefronts were lettered for Fort Smith.
The branch was abandoned when the Ridgway Reservoir construction provided a handy excuse for the D&RGW to pull it up.
