Yeah I have it on good authority that the original plans for the 3rd Big Dipper at Luna Park was going to be a custom designed Gerstlauer Eurofighter. It would have utilised the Tumblebug slab and also ventured out behind Coney and then back again. It would have been , through necessity, a unique layout. There is a POV and animation video of this ride in existence which I have yet to view. The Intamin Hot Racer was selected late in the planning and I guess the reasons for its selection would definitely include noise suppression versus the Eurofighter,which having a chain lift , would be fairly loud. I am sure that a custom Eurofighter at Luna Park would have been a great ride experience but I am pretty chuffed that the park opted for the worlds first and very unique single rail launched coaster.
Many of the rides that eventually made selection have also slightly changed , both in name and theming. The original planning for the rides definitely had greater theming aspects tied in with the 9 new rides and dare I say, in my opinion, superior names. The theming involved , whilst not overly extensive, is definitely a step up from what we are actually getting and hearkens back to the 95 incarnation and the use of bridges. I am thinking that money and expense is what has curtailed these elements back from initial planning and we must not forget that LPS has put in a significant $30 million investment for the 9 rides it is adding. What is being added is appropriate for a boardwalk style amusement park but of course, the theming and added bridges to each ride are certainly sorely missed.
