Thanks for the pix -- mirroring my own 1967 first contact with the Narrow Gauge in June of that year at age 7.
The day before riding the train, our family was in the old Durango Safeway (near the tracks?) getting supplies for the next day when the evening train arriving from Silverton came whistling into town. I made a mad scramble for the front of the store for a glimpse. First time hearing a sound I'll never forget.
Next morning, we kids were firmly in our seats during boarding when Dad disappeared...and eventually came back with a little book called Cinders & Smoke, still a cherished and well-worn treasure.
Your pictures around the Durango yard fill the gap of things I was too young to see or understand. Amazing to know I was there before the end of narrow gauge freight.
