I already ask last May at O scale west 2017 in Santa Clara. I ask about the Colorado Eagle, and was told not likely. The magic number is 20 sets. They have a hard of enough time getting those figures for the diesels. I sent Scott and Jonathan about 2lbs of data for the Mopac PA's, if the builder gets it right it will be stunning , same for the Porthole Mopac E6's
Reason I make this comment is the recent Mopac E8 models were very short coming, for correct data supplied or had.
