The Milan trolleybus system (Italian : Rete filoviaria di Milano) is part of the public transport network of Milan, Italy. In operation since 1933, the system presently comprises four routes.

History

A trolleybus system was established in Milan in 1933, with the opening of the short route 81 (Piazza Spotorno – Piazza Dergano).

In subsequent decades, the system developed rapidly, with the opening of radial and tangential routes. The new external circular route (originally CE (circolare esterna), now 90/91) was built as a trolleybus line.

In the mid-1970s, it was intended to transform the 90/91 circular route into a light rail line, and abandon the rest of the trolleybus network. Many trolleybus routes were therefore converted into bus routes, and their overhead wires were removed.

Routes abandoned during the 1970s and 1980s were:

81 and 82 (closed 27 September 1976);
83 and MB (closed 25 October 1976);
95 (closed 20 September 1977);
96/97 (closed 5 March 1979);
84 (closed 6 February 1984).

In subsequent years, following the abandonment of the proposal for the 90/91 tram line, there were no more interventions on the system, except for some limited changes to the routes.

Currently, efforts are focused on reducing journey times, with the construction of dedicated lanes. There are no plans to expand the system.

Service

The four routes are:

90 clockwise circle line (Viale Isonzo - Lotto M1 - Viale Isonzo);
91 counter-clockwise circle line (Viale Isonzo - Lotto M1 - Viale Isonzo);
92 Viale Isonzo - Bovisa FN;
93 Viale Omero - Lambrate M2.

Fleet

Past fleet

The fleet comprised many different types of trolleybuses during the 20th century, including many vehicles built by Alfa Romeo and Fiat and smaller batches built by other manufacturers, such as Isotta Fraschini.^[1]

The following types were still in service during the 21st century^[1] but are retired now:

70 Socimi 8820 trolleybuses on Fiat 2470.12 chassis (nos. 901–970),^[2] built in 1983–1985.^[1] Many were sold or dismantled in 2008/2009 (ATM sold 23 vehicles to Ruse, Bulgaria). The last units in service in Milan were withdrawn in November 2023.^[3]
33 Bredabus 4001.18 F04 articulated trolleybuses (nos. 200–232),^[4] built in 1992–94; last active unit (no. 230) was withdrawn in April 2024.^[5]
8 Autodromo (Carrozzeria Autodromo Modena, or C.A.M.) Busotto (nos. 300–307), also known as MAN NGT 204 trolleybuses, as Autodromo constructed them on MAN chassis; built in 1997. By spring 2023, all had been taken out of service,^[6] and only two remained in storage.^[7]

Current fleet

Milan's current trolleybus fleet is as follows:

33 Socimi F8843 articulated trolleybuses on Iveco 2480 chassis (nos. 100–132),^[8] built in 1991–1995.^[1] Although all 33 received "Socimi" badges on the front, Socimi only completed the first unit (no. 100), and then discontinued all trolleybus production, with Macchi being hired to complete the manufacturing of the bodies and overall production of the remaining 32 vehicles.^[9]
10 Irisbus Cristalis type "ETB 18" articulated trolleybuses (nos. 400–409),^[10] built in 2006–2007; only two (406/7) were still active in March 2024.^[3]
45 Van Hool AG300T articulated trolleybuses (nos. 700–744),^[11] built 2009–2012 and purchased in three orders of 15 each. The first two vehicles entered service in April 2009^[12] while the last batch of 15 (nos. 730–744) arrived between December 2011^[13] and May 2012.^[14]
80 Solaris Trollino IV 18-metre articulated trolleybuses (nos. 800–879),^[15] built in 2019–2023, and delivered in two separate batches. The first thirty (800–829) entered service between May 2020^[16] and June 2021. An order for 50 more (to be nos. 830–879) was placed in November 2021;^[17] the first unit entered service in June 2023, and at least 29 of the 50 had entered service by February 2024.^[3]

Preserved vehicles

1 Fiat 2472/Viberti articulated trolleybus (no. 548), built in 1958. Retired from regular service in 1996 and renovated in 2008.^[18]

Depots

There are presently two large trolleybus depots in Milan. The first depot is located in Viale Molise, east of the city. This depot accommodates about 70 trolleybuses and 40 articulated trolleybuses. The second depot is in the west of the city, and more specifically in Via Novara. It hosts about 40 articulated trolleybuses.

Both depots are used not only for the storage of trolley buses, but also for diesel powered buses. In contrast with the depots used solely for diesel buses, these depots are fully covered, for the better safeguarding of the fleet.

Opened in 1954, the system had progressively replaced the Lugano tramway network by 1959, and was significantly expanded between 1975 and 1981. However, it was closed in 2001, and the overhead wires had been completely removed by the summer of 2002.

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.
