My longest sessions have been, before this year, around 4 hours at a stretch at our Kennywood holiday set-up. This year, they extended the hours, first to 5 hours (at which I ran two days), and now to 7 hours on 11 of the remaining 18 days of this event, and 6 hours on another 4 of them. I'm kind of leery about running my engines for 6-7 hours straight. At 5 hours, they get just a little warm, but not hot. At other shows, we usually run engines for 2-3 hours at a stretch and swap them out, but I have been running 2 Polar Express consists (white roof/black roof) on the same line at the same time. Will have to do some thinking on what to do here.
