Hahaha!  Horrible joke.  Didn't it kill someone as "Rail Blazer?" Or did they take the stand up trains off for a different reason? 
   
When it first opened the Mine Train had two tracks which were identical.  They then changed one side to a "stand-up" train system.  Someone was killed and they then took that side out.  That track is currently at Dollywood (someone correct me if I am wrong) and runs as a normal mine train.
