Here's an idea that will definitely be the final ride sat the Hetch Hetchy Museum. Which will be an Immersive Train Like Experience, that will tell the History of the Hetch Hetchy Railroad.

That's based off this ride, found at Futuroscope in France. (Actual ride system to be used will be chosen and determined).

The Show Building with the track, will be a 14 sided Tetradecagon, or a 16 sided Hexadecagon, with Six or seven movable Diorama Scenes and Show Stopping Diorama Scenes, Plus the Load/Unload Platform.

Each train will have five special made cars, that will have Sideways Seats. That are based off the ones used in the Disneyland Railroad.
