From the 1820s onwards, vehicles similar to buses were used by men. For example, horse drawn carriages were quite popular during those days. During the 1830s steam buses were introduced. Electric trolleybuses came into use from 1882. The first motor buses, using internal combustion engines, rather than steam power, entered service in 1895.
The first mechanically propelled omnibus appeared on the streets of London on 22nd April, 1833. These vehicles 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.
Carl Benz had produced a motorized bus as early as 1895. In the same year, he started operating a regular line service on the 15 km route between Siegen and Deutz in Germany. Frank Searle designed the first mass-produced, double-decker bus. It was operated by the London General Omnibus Company. Contemporary buses began to evolve from the 1950s onwards.
