Trolley buses are public transportation vehicles that draw their power from overhead electrical wires. These buses have been in operation since the early 20th century and have become a staple in many cities across the world. Trolley buses are often referred to by different names, including trackless trolleys and trolley coaches. Other synonyms for trolley buses include electric buses, electric trolley buses, and electric-powered buses. In some regions, they are called "buses de Recoletos," "Bendy-buses," "trolley-trucks," or simply "trolleys." While the name may vary depending on where you are, the purpose of these vehicles remains the same - to provide efficient, eco-friendly transportation to thousands of people every day.
