"Trolleybuses in Valpara\u00EDso, Chile, have provided a portion of the public transit service since 1952. The trolleybus system is the second-oldest in South America. The originally state-owned system has been privately owned since 1982, and since 1994 it has been Chile's only operational trolleybus system. Almost two-thirds of its vehicles were built in 1946\u201352 by the Pullman-Standard Company, and they are the oldest trolleybuses in regular service anywhere in the world."@en . . .
