Trolleybus infrastructure

Trolleybus infrastructure consists of overhead wires, called catenary lines, and supporting poles installed along streets. Trolleybuses have poles with trolley wheels that connect to these wires, drawing electrical power to operate. Stations or stops are strategically placed for passenger pickup and drop-off. The system requires regular maintenance of wires and supporting structures to ensure safety and reliability. Unlike buses, trolleybuses need continuous electrical connection, making infrastructure essential for their operation. This setup allows trolleybuses to run emissions-free on city streets, providing a sustainable and quiet transportation option.
