Although there had been experiments with the use of a new form of transport - the 'trackless tram' (better known as the trolleybus) - during the first decade of the 20th century, it was in June 1911 that Bradford and Leeds became the country's pioneering operators of trolleybuses. There had been earlier experimental users - in places like Hove and London - and as the tide turned against the tram in many towns and cities, the trolleybus became a popular alternative with London becoming, for a period, the world's largest operator of trolleybuses.
