Gemini trains sitting by mean streak

I was at Cedar point yesterday and I went to get in line for mean streak. In line I noticed several blue train cars from gemini sitting off to the side. I also noticed some yellow and purple cars that I'm guessing were old corkscrew cars but does anyone know why those gemini cars are there?

There used to be 3 trains per side on Gemini. A few years ago (2003?), they stopped running 3 trains and went to 2. The trains by Mean Streak are the extra set of trains.

The yellow and purple Arrow trains that you saw are from Double Loop (Geauga Lake). I believe they're being used for spare parts for Corkscrew, although I'm not 100% sure

Three things you need to fix anything in the universe: duct tape, WD-40, and a hammer. Duct tape if it moves and it shouldn't, WD-40 if it doesn't move and should, and the hammer as the last resort.
