We are interested in riding the narrow gauge railroad train in Northern New Mexico/Southern Colorado. It's called the Cumbres & Toltec Narrow Gauge railroad. It starts in Antonito Colorado and takes about 8 hours to make it through the Mountains to Chama NM. Has anyone done the trip? Any suggestions? Best time of year to go? It seems to stop around mid-October due to the snow making the mountain passes impassable.
