Are they really going to reattach it?
It seems like it would be easier to maintain if they just left it off.
I don't see why they wouldn't. 1) The story doesn't really make sense without it. No one past the first row can see that the track just ENDS. Plus, the torn up track implies that the legendary Yeti was there, thus diverting the train off the correct forward path. 2) It was in good show condition for, what? 6 years, up until that hurricane. I'm sure however they're repairing it, they'll be using something more secure than simple wood glue to ensure it lasts even longer this time around, thus not needing that level of maintenance (i.e. removing the entire section) for a long time.
