Trolleybus history
Trolleybuses are electric buses powered by overhead wires through poles called trolley poles or pantographs. Their development began in the early 20th century as a cleaner, quieter alternative to streetcars and buses fueled by gasoline or diesel. They gained popularity in cities seeking efficient urban transportation without air pollution. Over the decades, advances in battery technology and urban transit needs led to some trolleybuses being replaced or modified, but they remain in use in many cities worldwide, valued for their environmental benefits and ability to operate on dedicated lanes with minimal noise and emissions, linking history with modern sustainable transit solutions.
