Trolleybuses in Valparaíso

Trolleybuses in Valparaíso, 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. In the 1990s and 2000s, almost half of the fleet continued to be vehicles built in 1946–52 by the Pullman-Standard Company, and by 1999 they were the oldest trolleybuses in regular service anywhere in the world, until the retirement of the last active Pullman trolleybus in March 2023. Those vehicles were collectively declared a national monument by the Chilean government in 2003. They helped the city gain its designation by UNESCO as a World Heritage Site, and have been called "a heritage sight in their own right" by at least one travel writer. In 1991–1992 the system acquired several secondhand trolleybuses from four Swiss cities. Even these vehicles, already old at the time of acquisition, became historic in their continued service after some 45–50 years or more, with 1959-built ex-Zürich number 105 being the oldest articulated trolleybus of any make still in service on any trolleybus system worldwide for almost 20 years until its retirement in May 2015. In the mid-2010s, a new group of secondhand Swiss trolleybuses, 18 1989-built NAWs from the Lucerne trolleybus system
