Definición y Significado de "trackless trolley"

What is a "trackless trolley"?

A trackless trolley is an electric vehicle that operates on city streets, similar to a bus, but is powered by electricity from overhead wires. It has tires, which allow it to move along regular roads, making it more flexible than vehicles that rely on tracks. The trolley connects to the overhead wires with poles on its roof, providing the energy needed to run. Trackless trolleys are used in some cities to offer an eco-friendly transportation option, helping reduce air pollution while offering a smooth and reliable ride for passengers.
