Yes I also think that the Itamin quad-rail would be awesome anlong with the ability to change them like bud7 said. But I also think that if you do flying coasters you'll need two side by side stations. With rotating track Like X-flight and even Superman. Cat walks with color change. without changing textures or the running rail color. And different station noises. The birds and people talking is getting old.
well, i don't think the station noise is bad, its very good. But it might be nice to change it..like for different themed tracks...
Also...shuttles can be created with the help of Tia....
yeah, just create the track, (don't use rel roll), then use tia's toolbox > shuutle maker ...and it will make the track dubble back on its self, with out looking it.... Just make sure the train dosn't go over the top of the last hill or what ever....
