Street railway is a term that refers to a rail track or set of tracks laid along a public roadway or a street. It is used to transport people and goods, primarily in urban areas. Synonyms for street railway include tramway, streetcar system, trolley system, light rail transit, and rapid transit. Tramways and streetcar systems are interchangeable terms that are commonly used in Europe and America, respectively. Trolley and light rail transit systems are similar to street railways but are usually designed to cover longer distances. Rapid transit systems, on the other hand, are high-capacity rail systems that operate in their own right-of-way. These terms are often used interchangeably and can vary based on the location and the purpose of the railway system.
