Also, on Wednesday only through Sept 3, you can take a mixed train from Alamosa to Antonito in the morning, which connects with the Cumbres train from Antonito to Osier. Take the return train from Osier to Antonito will then connect with the northbound version of the mixed train back to Alamosa. When I did this several years ago, there were 3 passenger cars on the mixed train (including a full length dome), and ZERO onboard crew on the return trip. I, and the one other passenger aboard, knew when it was safe to disembark upon arrival back at Alamosa when the engineer gave one long toot on the horn -- which is the standard signal to indicate that brakes are set and the train has come to a complete stop.
