Hey, Russ, I wouldn't get your hopes up too much. Shay #12 is committed to two events at the Colorado Railroad Museum during the month of August, and Shay #14 is not in running condition at the moment (bad axle). And while Phil Reader would probably enjoy seeing the #12 make the climb out of Chama, I'm sure he would be the first to tell you that any decisions regarding the use of the Shays are not his to make; the locomotives remain the property of the Ashbys.
Then there are transportation logistics and costs and on-site maintenance issues. And are either of the Shays currently FRA-legal (Mike Ramsey could answer that question; I can't)? Sorry to be a wet towel on the idea.
