For more than a century trolley buses have been providing transportation in towns and cities throughout the world. The trolley bus offered several advantages over other vehicles, primarily quiet operation, quick acceleration from a standing start, hill-climbing ability and a long life span. During the 1950s and 1960s, many trolley bus systems were abandoned. The oil crisis of the 1970s marked a turning point, and the number of trolley bus systems in the world has risen steadily since.
