I have talked to the president of the U.S. based company, and he has said that they do infact use the NoLimits Simulator for showcasing their rides.
Inspired by this, I set out to design an X-train Concept Coaster. Basically, it is a coaster type that differs slightly from the X-car, in the matter that it has 3 or more cars per train. It will utilize the standard low power consumption LSM launch that the company is famous for.
Here's some stats off the top of my head:
~80ft. max height
~2,200 ft. of track
55mph top speed
4 inversions (2 Immelmanns, 2 Corkscrews).
What I've gotten completed sofar:

Finishing up the queue lines, the station, and the catwalks tonight. Hopefully, I'll have the track out soon, before My Batman ride comes out.
