I'm a North Creek fan, but I would read this article before implying that the train is responsible for the growth of the area:

I think the area is cool enough to stand on its own. Real estate prices are ridiculously cheap compared to other ski towns (especially when you consider the relative proximity to metropolitan areas), rafting/kayaking gives it a legitimate summer draw (hiking and mountain biking also, but not as much as the lake placid area), and there are some decent food options (once again, though, LP and VT dominate NC in this realm).
If the train makes a profit without subsidies, cool, but I'll never ride that slow thing again and I wouldn't be so quick to ascribe the growth to the train.
