Delightful story.  I worked two summers as a carman (also known as "car toad") helper for the former Burlington railroad, rode the Antonito-Chama line, and looked over the Durango-Silverton run.  I am delighted that the silver-haired craftsmen are working to put his chunk of US and Alaska history back on the rails.  I am also pleased that safety is a major focus, something that can be neglected in volunteer efforts.
