Trams appeared in urban streets in the 198s, first of all trams, which were invented by Werner von Siemens, a German, in 1881. At that time, the tram had to run on a fixed track because it had to rely on the rail to form a power supply loop, which was very inconvenient in crowded places.

in p>1911, the world's first trolley bus started to operate in Britain. This kind of car gets power from overhead wires on the roof, and tires replace the rails. Trolley cars are more flexible than trams and are very popular.

nowadays, trolleybuses have been widely used all over the world, except that some cities still use trams. British-made double-decker trolleybuses are also popular in some countries and regions. In 1914, China began to use trolleybuses in Shanghai. Trolley cars are used in big cities such as Beijing, Guangzhou, Tianjin and Wuhan.

With the emphasis on environmental protection, trolleybus, as an environmental star without air pollution, is more popular with people. In 1888, American spola Geiger contacted an overhead transmission line with a trolley pole in Richmond, with the rail as the other pole. He improved the current collector, control system, suspension method and driving mode of motor in vehicles.

so modern trams appeared. Our country established the tram transportation system in Tianjin in 196. Later, Shanghai, Beijing, Shenyang, Harbin and Changchun successively built tram systems. Until the end of 195s, trams were still an important means of transportation.
