The improbable daily train keeping the lengthy segment of storied narrow gauge line from Antonito, CO to Chama, NM in active service comes steadily chuffing up the long valley as if unencumbered by the passage of time. The way rail travel should be - open windows and vestibules. About halfway between Los Pinos and Cumbres, the venerable 487 presents a nearly timeless image as it climbs through the high country.
