The Boston-area trolleybus system formed part of the public transportation network serving Greater Boston in the U.S. state of Massachusetts. It opened on April 11, 1936, with a large network operating for the next quarter-century. Measured by fleet size, the Boston-area system was the second-largest trolleybus system in the United States at its peak, with only the Chicago system having more trolleybuses than Boston's 463. After 1963, the only remaining portion was a four-route cluster operating from the Harvard bus tunnel at Harvard station, running through Cambridge, Belmont, and Watertown. The Massachusetts Bay Transportation Authority took over the routes in 1964.
The Tateyama Tunnel Trolleybus, officially the Trolleybus Line, is a Japanese trolleybus line in Tateyama, Toyama, operated by the Tateyama Kurobe Kankō Company.

It is also the last remaining right-hand drive trolleybus line in the world. The line is a part of the Tateyama Kurobe Alpine Route. The line originally opened as a normal (diesel) bus line in April 1971, but was later re-equipped for trolleybuses. The trolleybus line opened on 23 April 1996.
Servicio de Transportes Eléctricos de la Ciudad de México (STE) is a public transport agency responsible for the operation of all trolleybus and light rail services in Mexico City. As its name implies, its routes use only electrically powered vehicles. It was created on 31 December 1946 and is owned by the Mexico City government. STE is overseen by a broader local governmental authority, Secretaria de Movilidad de la Ciudad de México (SEMOVI)(Secretariat of Mobility of Mexico City), formerly (SETRAVI) which also regulates the city's other public transport authorities, including Sistema de Transporte Colectivo, Red de Transporte de Pasajeros del Distrito Federal and Metrobús, as well as other forms of transportation in the district. STE's passenger vehicle fleet consists exclusively of trolleybuses, light rail, and aerial lift vehicles, and in 2007 its network carried 88 million passengers, of which 67 million were on trolleybus services and 21 million on light rail.

The Avellino trolleybus system forms part of the public transport network of the city of Avellino and the province of Avellino, in the region of Campania. Trolleybuses originally served the city from 1947 to 1973, on a route that also extended outside the city to the neighbouring towns of Atripalda and Mercogliano, and then the system closed. However, in the 2000s work to build a new trolleybus system got under way and new vehicles were purchased for it in 2007, and were delivered in 2014. The project experienced several delays after the start of construction in 2009, but most issues had been resolved by 2020 and construction was largely completed by 2021. Throughout its planning and construction, it was inaccurately referred to as the "metropolitana leggera", when in fact it was never planned to be a rail line, and always planned to be a trolleybus line. The last round of testing took place in December 2022 and January 2023, and the new trolleybus system opened for service on 3 April 2023.
