trollibussi

Trollibussi is a Finnish term that generally refers to a trolleybus. Trolleybuses are electrically powered buses that draw power from overhead wires through poles or pantographs. Unlike trams, trolleybuses run on rubber tires and can deviate from their fixed tracks, offering greater flexibility in routing. The term "trollibussi" is a direct transliteration of the English word "trolleybus". In Finland, trolleybus systems were historically operated in cities such as Helsinki and Tampere. However, most of these systems have since been replaced by diesel buses or modern electric buses that do not require overhead infrastructure. The operation of trolleybuses requires a significant investment in infrastructure, including poles, wires, and substations. While they produce no local emissions, the electricity used to power them is often generated from fossil fuels, depending on the country's energy mix. Trollibussi operations are a part of public transportation history in Finland, though they are less common today.
