By 1965, most UK trolleybus systems had closed, and the manufacturers of the overhead equipment gave notice that they would cease production. At the same time the trolleybuses were criticised in the local press because they cost more to operate than motor buses and were inflexible, even though the trolleybuses were profitable (Reading's motor buses made a loss), faster and less polluting. Reading Corporation decided to abandon the trolleybus system, and the routes were phased out between January 1967 and November 1968.
