Yes. That was my thinking too. If E&P 4 or SP 18 were there, include them too. My thinking was along the line of what D&S did in 2010 with 7 hot locos out front of the Depot after the Parade on Saturday of Railfest that year. They had E&P 4, 315, 473, and all of the 36s. I will get this wrong but as I recall 480 and 482 were not in use at the time but were fired up and run to the depot to pose with the others as they came in. The photos of all blowing their whistles at the same time (Goose 5 laid on its horn too) was a neat experienc.
So my point was, it appears to me that C&TS could do something for the first time in its history, gather six operating locomotives at the same time on the road. I'm sure it would not be a first for the location but it would be for the C&TS I am sure. "Look at the C&TS go!"
