Rick brings up the point I hinted at. Catering to a touristy public in bits and pieces may lead to a slippery slope, ending in Disneylandesque artificialdom. That result is, at this time, exactly the antithesis of the Cumbres.
But the others have valid points, that appealing to the "average joe" may be the only way to increase revenues from fares to cover costs. There have been many discussions of the costs of operating a line like the Cumbres, and we know it does not benefit like other tourist lines from the combination of fame, a smaller physical plant, lower equipment stress, and/or closer proximity to the huge, drooling, urban masses.
I feel that the point of all this chatter about appearances, is really a discussion of how to guarantee the future of the entity known as the C&TS. To contribute to this discussion it is my opinion that in this age of skyrocketing costs that any high quality railroad museum will need to transform its revenue reliance from the tourist railroad fares to a interest from a well-invested foundation (or governmental taxation), in the next decade or so. I predict that those who don't will only be a shadow of their former selves or dreams.
