Trolleybuses are a type of electric bus that draws power from dual overhead wires. They operate similarly to trams but are designed for road use, allowing them to navigate city streets while providing a clean and efficient mode of public transport. Trolleybuses are often quieter and produce fewer emissions compared to traditional diesel buses. These vehicles are equipped with poles that connect to the overhead wires, supplying electricity to their electric motors. Trolleybuses can be found in various cities around the world, contributing to urban mobility and reducing reliance on fossil fuels. They are part of the broader category of electric public transport systems, which also includes trams and light rail.
