I will check my photos to be sure, but I'm pretty sure that this is the one now sitting in the maintenance storage area behind Duel. Presumably it's been used for spare parts for the rest of the fleet.
I was given a tour around some staff areas, and yes, the Daisy Train is in ruin behind Duel. It's in a bad state and it doesn't look like we'll ever be seeing it in operation again.
Life is a roller coaster. You can either scream every time you hit a bump or you can throw your hands up in the air and enjoy it.
