Doom Buggy is the show name for Disney's OmniMover system. It was initially developed for the "Adventures in Inner Space" attraction by a team led by Bob Gurr.
The cars, linked together, move forward via a 12-volt electric drive
train. The vehicles themselves have no means of locomotion. They are driven by a series of ten motors located throughout the
ride. Each
car can also be rotated 180 degrees--from facing forward to facing backward.
This rotation, combined with scalloped design of the
car, allows the designers to control what the guests see at any given time.
Each
car is also equipped with 3 speakers. The sound (which is not stereo, as commonly reported) is transmitted to odd-numbered cars via a narrow
band transmitter. The signal (once received) is then passed on to the even-numbered
car behind it.
Disneyland's Haunted Mansion has 131 cars, with a guest capacity of 2,618 guests per hour, granting 2.25 guests per
car, assuming no
ride stops (wheelchairs or
slow guests). A typical hour at full capacity is 2000-2400.
Walt Disney World's Haunted Mansion has 160 cars, due to its longer track, with a guest capacity of 3,200 guests per hour.
