TROLLEY BUS Meaning and
Definition
-
A trolley bus is a type of electric vehicle used for public transportation, typically operating in urban areas. It is designed with a combination of features from both buses and electric trams, making it an efficient and environmentally-friendly mode of transport.
The defining characteristic of a trolley bus is its power source, which is usually obtained from overhead wires. These wires, also known as trolley wires or catenary wires, are installed above the roads and supply electrical energy to the vehicle through an electrical pickup device called a trolley pole or a pantograph. By connecting to the wires, the trolley bus can draw electricity to power its electric motor, enabling it to operate silently and emit no exhaust emissions, reducing air pollution compared to conventional diesel-powered buses.
Similar to regular buses, a trolley bus features multiple doors for easy passenger access and exit, as well as seating and standing areas to accommodate a significant number of people. It usually operates on designated routes, following a fixed schedule. However, given its electric power supply, it relies on a network of overhead wires, making its flexibility limited to areas with the necessary infrastructure.
Trolley buses are popular in cities worldwide due to their lower environmental impact, quieter operation, and greater energy efficiency compared to traditional bus systems. While they require initial investment in the installation of overhead wires, their long-term benefits include reduced dependence on fossil fuels and improved air quality.

Etymology of TROLLEY BUS
The word "trolley bus" has an interesting etymology that combines elements of both American and British English.
The term "trolley" is derived from the American English term for an electric streetcar or tram, which was originally powered by overhead electric wires. This type of vehicle was first introduced in the late 19th century in the United States. The "trolley" refers to the winding mechanism used to collect electricity from the overhead wires, which resembled a trolley wheel.
The word "bus" comes from the Latin word "omnibus", meaning "for all". It was first used in the 1830s to describe a horse-drawn carriage that transported multiple passengers at once. Over time, the term "bus" evolved to refer to motorized vehicles designed for public transportation.
