When I visited Chama in 1995, steam locomotives were being used to haul freight as well as passengers. Visiting Chama seemed like traveling through a time warp to the 1920’s.
One of the beauties of Chama is that the yard is open - no fencing and visitors can wander at will. The camera just showed a family with two children and a dog cross the tracks to the vicinity of the engine house (but they can’t go inside). Parents (and adults) are responsible for their own safety around moving locomotives and cars. Something not usually seen in the 21st century!
The freight cars are restored and mostly for special photo specials. They are having a special photo tour mid-month with participants coming from Europe and Asia. See the link.

Local freights carry ties and ballast for track work. The track is in better shape than many freight short lines.
