| - Regular intercity bus services by steam-powered buses were pioneered in England in the 1830s by Walter Hancock and by associates of Sir Goldsworthy Gurney among others, running reliable services over road conditions which were too hazardous for horse-drawn transportation. Steam carriages were much less likely to overturn, and did not "run away with" the customer as horses sometimes did. They travelled faster than horse-drawn carriages (24 mph over four miles and an average of 12 mph over longer distances). They could run at a half to a third of the cost of horse-drawn carriages. Their brakes did not lock and drag like horse-drawn transport (a phenomenon that increased damage to roads). According to engineers, steam carriages caused one-third the damage to the road surface as that caused by the action of horses' feet. Indeed, the wide tires of the steam carriages (designed for better traction) caused virtually no damage to the streets, whereas the narrow wheels of the horse-drawn carriages (designed to reduce the effort required of horses) tended to cause rutting. However, the heavy road tolls imposed by the Turnpike Acts discouraged steam road vehicles and left the way clear for the horse bus companies, and from 1861 onwards, harsh legislation virtually eliminated mechanically-propelled vehicles altogether from the roads of Great Britain for 30 years, the Locomotive Act of that year imposing restrictive speed limits on "road locomotives" of 5 mph in towns and cities, and 10 mph in the country. In 1865 the Locomotives Act of that year (the famous Red Flag Act) further reduced the speed limits to 4 mph in the country and just 2 mph in towns and cities, additionally requiring a man bearing a red flag to precede every vehicle. At the same time, the act gave local authorities the power to specify the hours during which any such vehicle might use the roads. The sole exceptions were street trams which from 1879 onwards were authorised under licence from the Board of Trade. In 1881, the engineer John Inshaw built a steam carriage for use in Aston, Birmingham, UK. Capable of carrying ten people at speeds of up to 12mph, Inshaw discontinued his experiments due to the legislation then in force.
