It's tough to make a return to Steamtown work financially. It takes 6 days of deadheading to get there and back. Without the ability to run excursions on the deadhead route, as we did in 2015, it simply does not work. We cannot cover the cost of 6 days of deadheading with only one or two weekends of trips out of Steamtown.
This is also why a return to the R&N is unlikely. It's just too far from home base.
