If you recognize any of the folks let me know. Just kidding.
The two (2) small buildings in front of the water tank in the bottom photo was a garage for the speeders and tool shed. The house facing the tank in the upper photo was where railroad employees lived. La casa de el cinero as it was known to the locals. (prouounced seenero in Spanglish). The house visable in the distance on the lower photo was the house where Alejandro Montoya and his wife Cruz Dimas Montoya lived.
You can make out the road leading to the mesa on the left of the lower picture.
The water to fill the tank that was then pumped into the steam engines came from the Pecos river a few miles away. There was an under ground concrete storage tank and a pump there. The pipeline ran from there to the tank. The water line for the most part was in or right off the arroyo.
