Spiral escalators acquire less horizontal space than straight escalators. However, in the early spiral designs were failures. For example, one spiral escalator constructed by Reno in combination with William Henry Aston and Scott Kietzman at London's Holloway Road Underground position in 1906 was dismantled almost right away and little of the mechanism survives. The Mitsubishi Electric Corporation has urbanized successful commercial designs and has contrived curved and spiral escalators since the 1980s.
Notable sets of spiral escalators are situated in the Westfield San Francisco Centre in San Francisco, California, and at Forum Shops at Caesars Palace in Las Vegas, Nevada. The Times Square shopping mall in Causeway Bay, Hong Kong, also features four curved escalators, as do Wheelock Place in Singapore.

Carriage
The standard definition of a carriage is a four-wheeled horse drawn personal passenger vehicle with leaf springs or leather robust for postponement, whether light, smart and fast or large and relaxed. Compare the public conveyance stagecoach, charabanc, and omnibus.
A medium that is not sprung is a wagon. An American buckboard or Conestoga wagon or "prairie schooner" was never taken for a carriage, but a waggonette was an enjoyment vehicle, with lengthways seats.
The word car meaning "wheeled vehicle", came from Norman French at the start of the 14th century; it was absolute to cover automobile in 1896.
In the British Isles and many Commonwealth countries, a railway carriage (also called a coach) is a railroad car planned and prepared for transporting passengers.
In the United States, a baby carriage is a wheeled transportation for recline infants (in English outside North America: perambulator or pram), often with a hood that can be adjusted to protect the baby from the sun.
