That's right. Carlos was the engineer and took the pictures for his shops update web site and in the caption and explained about the reverse loop in Antonito being full of passenger cars. He had to back in to hook up for the next days run.
This is the reason I think the C & TS should look to add a track off the reverse loop back toward the Antonito Station where they could back and store a waiting passenger train.
I realize they have other major projects now but it isn't far to the SL & RG tracks, maybe 50 yards and they could throw a third rail on their siding and revert back to the dual gauge days.
All that is needed is money, time and desire.
