Different Chaos Cars?

Has anyone noticed that there are cars that appear to be for chaos back behind Mean Streak? They are located behind the shed, next to the Gemini Trains. Any idea what these are for? Did they replace them recently?

I'm sorry. I hate when people do that, then I go and do it.

Don't worry about it. It was just easier for me to link to the other thread than to explain everything.
