I absolutley love the WDW Railroad. But what is the appeal of it? Live steam, theming, etc.?

For me I think it would have to be that its operated as close to a real railroad as possible. With the lifelike station announcements, spiels and music, and the intense attention to detail. All of that and the live steam locomotives, it makes it one of my favorite attractions in the park. That and I'm a railroad buff!

What about you?
