A trolleybus is a type of electric bus that runs on city streets, powered by electricity supplied through overhead wires. Unlike regular buses, which rely on fuel, trolleybuses have two poles on the roof that connect to the wires, providing the power needed for the vehicle to move. They are quieter and produce less pollution than traditional buses. Trolleybuses are commonly used in cities with the necessary overhead wiring system, providing an efficient and environmentally friendly way to transport passengers over short to medium distances.
