Trolibuszhálózat refers to a trolleybus network, a public transportation system that uses trackless, electric buses powered by overhead wires. Trolleybuses draw electricity from these wires through poles or pantographs, which connect to the supply. This system offers a quiet and emission-free alternative to diesel buses, contributing to reduced air and noise pollution in urban areas.

The development of trolleybus networks began in the late 19th and early 20th centuries, often as an extension or replacement for tram systems. They provided greater flexibility than trams, as they were not restricted by fixed tracks, allowing them to navigate around obstacles or use existing road infrastructure more easily. Many cities established trolleybus lines to modernize their public transport fleets and reduce reliance on fossil fuels.

Trolleybus networks require significant infrastructure, including the installation and maintenance of overhead electrical lines, substations for power distribution, and charging facilities. The operational costs can be competitive, especially in areas with established electrical grids. However, the initial investment in infrastructure can be substantial.

Over time, the popularity of trolleybus networks has varied. Some cities have expanded their systems, recognizing their environmental benefits, while others have phased them out in favor of diesel buses or other forms of public transport like light rail or modern electric buses that do not require overhead lines. Despite these shifts, trolleybuses continue to operate in numerous cities worldwide, forming an integral part of their urban mobility solutions.
