I agree with Ed.
I do believe that now that Uncle Pete is out of the picture, it would be of value to find a way to cross the ditch and add a third rail down the northwest leg of the wye, so that the C&TS train could start at the historic Antonito depot. There would still need to be a stop at the 'not quite historic' new depot if only because of the parking facilities.
The historic depot has the benefit of being adjacent to the commercial part of Antonito, and who knows--the NG passenger could leave after the SG passenger arrives. Hmm, kind of like the San Juan and Chile Train!
Now, how all this gets orchestrated with train movements is another matter entirely!
