I think it's pretty amazing that they keep track of all the parts! There are a LOT of components to a roller coaster, from the track itself to all the nuts, bolts, and electrical/hydraulic equipment.
In watching X-Flight-uh-Firehawk's move to KI, the tracks and supports are all numbered so that part is probably easy. They had TONS and TONS of new nuts and bolts.
As for the electrical stuff, I imagine ALOT more goes into that part.
Jason thanks so much for the updated process (regress?) of the end of GL. Seeing Dominator's tracks sitting in the parking lot so makes me want to drive up there and get some pics myself. Going to miss that coaster, going to miss the park!

It's all about getting around the barrels, or over the fences, right leads, no faults, fastest time and looking pretty when done. What's so hard about that?
