A trolley car, also known as a streetcar or tram, is a type of public transportation vehicle that operates on tracks laid on city streets or dedicated rail lines. It is a medium-sized electric-powered vehicle designed to transport passengers within urban areas.
Typically, a trolley car consists of a single or multiple connected cars with a flat, elongated body resembling a bus. The vehicle is powered by electricity that is supplied through overhead wires, known as trolley poles or pantographs, which draw power from an electric power network. This electric power is transmitted to the motor, located either beneath the vehicle or in one of the cars, which propels the trolley forward.
Trolley cars are operated using a fixed route system with predetermined stops, similar to buses or trams, and passengers board and alight through designated doors along the sides. In some modern trolley cars, there may be low-floor entrances at the front or rear, allowing easier accessibility for individuals with disabilities or those using strollers or wheelchairs.
Trolley cars have been in use since the late 19th century and have played a significant role in urban transportation history. They offer a cost-effective and environmentally friendly means of public transit, reducing reliance on fossil fuels and minimizing air pollution. Trolley cars continue to be used in cities worldwide, providing a reliable and efficient mode of transportation for urban residents and commuters.
The word "trolley car" is derived from the word "trolley", which originally referred to the wheeled cart or trolley used to transport goods in the 19th century. The term "trolley" comes from the verb "troll", meaning to roll or wander, which originated from the Old French word "troller" or "troller" meaning "to wander".
In the late 19th century, when electric streetcars were introduced, these vehicles were initially referred to as "electric trolleys" due to the trolley-like pole system they employed. The streetcar would draw power from an overhead wire by means of a trolley pole, which was a long, flexible pole equipped with a small wheel or "troller". The troller would make contact with the wire, supplying electricity to the vehicle and allowing it to operate.
