The Scenic Railway at Luna Park Melbourne, Australia, is the longest continually-operating roller coaster in the world.
There doesn't appear to be anything called the "Mickey Mouse Roller Coaster", there is the Gadget's Go Gadget Coaster in Mickey's Toontown at Disneyland but the weight of the coaster is unknown.
