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.
