A steam carriage is a type of vehicle powered by a steam engine, designed to transport passengers or goods. It operates by heating water to create steam, which then drives pistons or turbines to produce motion. Steam carriages were among the earliest forms of mechanized transport, emerging in the early 19th century. These vehicles played a significant role in the development of road transport, paving the way for modern automobiles. Notable inventors like George Stephenson and Nicholas Cugnot contributed to the advancement of steam carriage technology, influencing future transportation innovations.
