Absolutely right.
The DLP trains should have the new wheel-sets within a couple of months. A little TLC to the Mountain itself and the ride should be good as new.
A word about the supports. When I was looking at the supports up close, they looked a bit unusual to me. Normally supports are bolted to footers in the ground, and extend up to the track. A few of the supports already on site look as though they will be attached to another support structure, or even part of the mountain. Time will tell.
Work is moving right along, most noticibly on the "villiage" area leading to the mountain, including bathrooms. Guests will be walking around in that area at some point while the mountain is still under construction. From behind the "big white wall" there is not much to see, as site work is still ongoing. When the actual mountain starts to go up, it will progress much faster, and should be "in the dry" by early next year at the latest.
Best I could find out, the trains haven't even been built yet. When they are they will be built at the Vekoma main plant. I think the track is being fabricated here, at one of Vekoma's US vendor plants.
