Great photo and information D.B! The best part of the earlier excursion's was that the hosting railroads trusted the steam engines out on the High Iron unassisted, no diesels. I remember seeing the 4449 steaming through the Bay area many times in the 1980s with her long daylight painted train always unassisted. However, I do remember a freshly washed SP diesel running about 5 minutes ahead of it a few time just in case. It was the only time I saw an SP scarlet and grey diesel that was clean and not extremely dirty. They had class back then. Keep them coming D.B.
