When entering the area where the Touch & Taste lab doors are sealed and the track looks like it's a loose piece of track..Is that track piece a part of the original layout or was it placed there just for the attraction?
There have been a few comparison shots of the old track vs the current track, but I can say for certain that the "track" that leads to the door for the taste and touch labs is fake. That wall actually backs up against another show scene, so there's nowhere for it to go.
There *is* an actual track switch along the ride path, but it leads to the maintenance bay. It's between the expanding room with all the Figments and the unload platform, off to your right. (It's in the darness of the singing moon scene)
The original track path was cut just after this maintenance spur. It looped down and around through what is now the post-show area, some as part of the attraction, and some as the original load/unload platforms. It then formed into the turntable circle of track, and re-connected to the current track about at the point where the trains emerge at the loading platform. Essentially they took the point on the track that was closest to the turntable curve, connected those two points, and cut out everything else.
Since its almost the same thing, what about Test Track, when you approach the Test Course "A" and "B", it diverts you to the left one. Does "B" lead you somewhere.
"Track Course B" leads to the vehicle storage track. It leaves the track at that point (after the Corrosive test for those who don't know the layout enough), goes under the handling turns, and joins the track in the darkness between non-ABS and with-ABS brake tests. Sometimes you can see an empty vehicle on your left as you approach the with-ABS brake test, waiting to be added onto the track. This track spur is intended only for fully operational vehicles that can be called into service at any time.
Test Track also has a separate maintenance bay track. It leaves the track by the seatbelt check (you can see it on your left), circles behind the unload platform (and over the on-ride photo area and some of the post-show), and re-joins the track at the far end of the loading platform.
From the maintenance bay, vehicles can also be wheeled outside and over to an external garage where they can have more-involved work done on them. (You can see this garage if you look down and to your right *immediately* before you re-enter the building after the high-speed loop)
