Travel

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.

The first mechanically propelled omnibus appeared on the streets of London on 22 April 1833. Steam carriages were much less likely to overturn, they travelled faster than horse-drawn carriages, they were much cheaper to run, and caused much less damage to the road surface due to their wide tyres.

However, the heavy road tolls imposed by the turnpike trusts 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 from the roads of Great Britain for 30 years, the Locomotive Act 1861 imposing restrictive speed limits on road locomotives of 5 mph 8.0 km/h in towns and cities, and 10 mph 16 km/h in the country.

Trolleybuses

Main article: Trolleybus

World's first trolleybus, Berlin 1882

In parallel to the development of the bus was the invention of the electric trolleybus, typically fed through trolley poles by overhead wires. The Siemens brothers, William in England and Ernst Werner in Germany, collaborated on the development of the trolleybus concept. Sir William first proposed the idea in an article to the Journal of the Society of Arts in 1881 as an ...arrangement by which an ordinary omnibus...would have a suspender thrown at intervals from one side of the street to the other, and two wires hanging from these suspenders; allowing contact rollers to run on these two wires, the current could be conveyed to the tram-car, and back again to the dynamo machine at the station, without the necessity of running upon rails at all.

The first such vehicle, the Electromote, was made by his brother Ernst Werner von Siemens and presented to the public in 1882 in Halensee, Germany. Although this experimental vehicle fulfilled all the technical criteria of a typical trolleybus, it was dismantled in the same year after the demonstration.

Max Schiemann opened a passenger-carrying trolleybus in 1901 near Dresden, in Germany. Although this system operated only until 1904, Schiemann had developed what is now the standard trolleybus current collection system. In the early days, a few other methods of current collection were used. Leeds and Bradford became the first cities to put trolleybuses into service in Great Britain on 20 June 1911.

Motor buses

In Siegerland, Germany, two passenger bus lines ran briefly, but unprofitably, in 1895 using a six-passenger motor carriage developed from the 1893 Benz Viktoria. Another commercial bus line using the same model Benz omnibuses ran for a short time in 1898 in the rural area around Llandudno, Wales.

Germany's Daimler Motors Corporation also produced one of the earliest motor-bus models in 1898, selling a double-decker bus to the Motor Traction Company which was first used on the streets of London on 23 April 1898. The vehicle had a maximum speed of 18 km/h 11.2 mph and accommodated up to 20 passengers, in an enclosed area below and on an open-air platform above. With the success and popularity of this bus, DMG expanded production, selling more buses to companies in London and, in 1899, to Stockholm and Speyer. Daimler Motors Corporation also entered into a partnership with the British company Milnes and developed a new double-decker in 1902 that became the market standard.

The first mass-produced bus model was the B-type double-decker bus, designed by Frank Searle and operated by the London General Omnibus Company—it entered service in 1910, and almost 3,000 had been built by the end of the decade. Hundreds of them saw military service on the Western Front during the First World War.

The Yellow Coach Manufacturing Company, which rapidly became a major manufacturer of buses in the US, was founded in Chicago in 1923 by John D. Hertz. General Motors purchased a majority stake in 1925 and changed its name to the Yellow Truck and Coach Manufacturing Company. GM purchased the balance of the shares in 1943 to form the GM Truck and Coach Division.

Models expanded in the 20th century, leading to the widespread introduction of the contemporary recognizable form of full-sized buses from the 1950s. The AEC Routemaster, developed in the 1950s, was a pioneering design and remains an icon of London to this day. The innovative design used lightweight aluminium and techniques developed in aircraft production during World War II. As well as a novel weight-saving integral design, it also introduced for the first time on a bus independent front suspension, power steering, a fully automatic gearbox, and power-hydraulic braking.
