This ride doesn't need a lift hill as the train is powered. The train will gradually gain speed on flat track, collect speed on drops and slow down on hills.
It is better to operate Mine Ride as only a single train since the train powers itself and the speed is collectible up to 35mph, the speed causing crash if the breakdown causes the ride Brake Failure.
In Real Life
The Mine Ride resembles Kiddie Coasters which are made by many manufacturers.
