I also prefer the westbound Antonito to Chama ride., mainly because the scenery gets better and better as you go. Stay in Chama and ride the bus to Antonito in the morning, return by train. The bus leaves at 8:30 and the train returns around 4:00 p.m., giving you some time in the afternoon. This year you also have the option to get off at Cumbres and bus to Chama, making the day even shorter if that is a consideration. If you ride the train from Chama to Antonito and take the bus return, you will get back to Chama much later. On the C&TS we pay extra for the parlor cars, but that is for adults only. If you think you'll spend a lot of your time in the open gon, then just stick with coach.
