Unless I wasn't looking close enough, the train does NOT go backwards during said drop. The engine part of the train is supposed to be the back, because it is a "steam donkey". Then again, maybe I wasn't looking close enough, so..
Not on the main drop, but on another part of the ride it goes backwards.
After seeing numerous pictures of the curved track section leading into a tunnel, I always imagined the train coming out of it. It was quite cool to see the train going into that tunnel.
I have heard and read in multiple places that the train does indeed go backwards at one point. If that's true, it would make EE even more of a unique attraction. I know the boats on Epcot's Maelstrom go backwards for a short time, but are there any other large coasters that do such a thing?
I know that it goes backwards in other parts, I just didn't think it went down the drop backwards.
In terms of other roller coasters that go backwards, any sort of shuttle or non-circuit launch coaster goes backwards at some point, however Expedition Everest is a full circuit roller coaster (from what I can tell). The only other coaster that I know of that may do this is Revenge of the Mummy, but I don't know much about that ride.
