Carwardine Parks/Cancelled Plans

Charles Dinn Zelda Themed Wooden Coaster Layout (Rose Park)
Charles Dinn personally sent Carwardine Parks a concept for a wooden coaster at Rose Park in 1991, Carwardine Parks approved it and would theme the coaster to the then-newly released "The Legend of Zelda: A Link To The Past", and have it open for the 1993 season, but the plans were cancelled as Dinn filed for bankruptcy, Carwardine then sent the layout to CCI, who denied the layout since they didn't have enough staff to build that big of a coaster at the time. The coaster was cancelled and all that came of it were trains made by D.H. Morgan, which would be relocated to Camp Carwardine to replace DFW Destroyer's original buzz-bar trains by PTC, which were becoming a safety hassle by then.

Simpsons Springs
Simpsons Springs was a land planned for Carwardine Colony and a few other parks back between 1995-1996 to expand upon the Simpsons concept than just the theatre, this land was to contain a motion simulator titled "Nightmare in Krustyland", a 1:1 scale recreation of Moe's Tavern and Krusty Burger (with Moe's Tavern being one of the few places in the chain to serve alcohol, in this case, Budweiser and Krusty Burger serving food provided by McDonald's) and several other landmarks, several drawings exist for the planned land and only features like the statue of Jebediah Springfield (from the Season 1 episode "The Telltale Head"), a gift shop at the exit of the Simpsons theatre and a grand statue featuring all the main characters and some of the side characters were built, the film "Nightmare in Krustyland" was completed but shelved until Halloween 1998 when it was shown at The Simpsons Theatre. Currently, all of the Jebediah Springfield statues and grand statues are in storage in a warehouse at Boblo Island since they originally lost the license in 2007.

Other plans included changing out the Jebediah Springfield statue every Halloween to a headless version (ala "The Telltale Head"; albeit the plans for the changing statue were scrapped early on) and having an Animatronic (or Walkaround Costume in some plans) version of Moe at Moe's Tavern.

In 2019, more plan files were found at Carwardine Studios, showing a possible shuttle launched coaster by Premier Rides similar to Schwarzkopf's Shuttle Loop.
