Trolley bus is a kind of public transportation which is powered by overhead catenary and driven by the electric motor as well as does not depend on the fixed track to travel. In some areas or countries, for instance, In Japan, trolley bus belongs to the scope of the track transportation. As a matter of fact, it has already been a kind of controversial public transportation in the contemporary era because trolley bus combines all the advantages and disadvantages of public buses and the track transportation. Today let me keep you informed of trolley bus as much as i can.
The body and chassis of trolley bus are the same as common public buses, but there must be a pair of receiving poles on the top of it, which is used to concentrate the power from overhead catenary and then form a current path of electricity as well as then make trolley bus normally run. In general, if the receiving poles of trolley bus are out of the track, trolley bus will lose the power. However, dual-source trolley bus which is installed the power battery, super capacitor and diesel generator can move and run offline on the roads where there are not the overhead catenary.
What’s more, the first trolley bus in the world was produced during the period from 13th, June to 29th, April, 1882, and the inventor of it was a German whose name was Werner von Siemens. After that, related experiments concerning the trolley bus were operated both in Europe and America. And the first trolley bus system in the world and with passengers started to be operated and run in Germany on 10th, July, 1901. Although the system was only operated and ran for three years, the operating principle and devices of it were the basic of electricity input and output system of trolley bus in the contemporary era.
