Trolleybuses in Chieti

The Chieti trolleybus system (Italian: Filovia di Chieti) forms part of the public transport network of the city and comune of Chieti, in the region of Abruzzo, central Italy. Comprising one urban route, the system opened in 1950, but a suspension of trolleybus service that began around the end of 1992 ultimately lasted almost 17 years, with service finally resuming in September 2009. In 2011, 17 Italian cities or metropolitan areas had trolleybus systems, counting four where the system was a new one under construction, and of all of these, Chieti was the smallest in population. By the early 1980s, it was already the smallest Italian city to retain trolleybus service (with Carrara second).

After service ceased at the end of 1992, it was described as a temporary suspension, with plans to repair deteriorated infrastructure, refurbish the vehicles, and reopen the route. Those plans did proceed, but with more delays than originally anticipated and with the scope of the plans expanded to include the construction of three new route sections and refurbishment of the vehicles. Construction only began in 2002, and limited service was reintroduced in September 2009, almost 17 years after trolleybus service had been suspended.

Trolleybus service on the section between Piazzale dei Martiri Pennesi and Ospedale Clinicizzato, which had been part of route 1 since the suspension of trolleybus service years earlier but always been served only by diesel buses, was finally introduced on 15 April 2013. In July 2013, five new low-floor trolleybuses built by Van Hool were placed in service, and by November 2013 they were the only trolleybuses still in service on the system.
