Short turns on C&TS

Shorter runs might make it more appealing but I don't think you will save much. Osier is a fixed cost for operation. Only food amounts change.
Wear and tear on the train might be less but I suspect not that much.
Bottom line is some savings can be more costly.

Maybe run short trains to lava for sunrise and maybe sunset. Maybe have conserts at Osier. Maybe equipment demos at various points like the pile driver.
Maybe they need a goose or better yet increase the premium cars. This is working for the D&S. Maybe they need a silver vista?
Bottom line is that though they are a living museum, ultimately they are in the entertainment business. The ride is part of it as well as the scenery. How do you get the masses to ask you questions though. This is how you know you have hooked them. If they sit and smile they will not tell many of the trip. But if you engage them they will tell others because they were challenged. Some short runs will be better for this but ultimately I feel this is a key over all for every part of the railroad.
