1949–1989 The Ancona trolleybus system opened on 15 March 1949, operated by the Azienda di Trasporti Municipalizzati Autofiloviari (ATMA). An interurban trolleybus line connecting Ancona with
Falconara Marittima opened on 26 June of the same year. and all other urban routes except route 1 were closed later in the 1970s. New
Menarini-built trolleybuses delivered in 1983 introduced a new all-over orange livery; the red-and-yellow livery continued to be worn by the fleet's older trolleybuses, but ceased to be used upon their retirement from service, in 1987. In 1985, route 1 was extended from the railway station to Piazza Ugo Bassi, bringing back into use a section of wiring used by former routes 2–5. In 1998/99, the wires of former trolleybus route 4 between Piazza Ugo Bassi and Tavernelle, which had been out of use since at least 1974, were completely renewed, with plans to reintroduce trolleybuses to route 4. trolleybus 4 inbound from Tavernelle in 2007, less than one year after trolleybus service to that hilly district was restored after 32 years On 9 November 2006, routes 1 and 4 were combined at all times as route "1/4"—a combination that had already operated on Saturday afternoons and Sundays for many years, but was now expanded to seven days a week and with routes 1 and 4 discontinued. However, route 1 service had been temporarily motorbus-operated since May and this initially continued following its replacement by route 1/4. Starting on 18 December 2006, about half of the new route's runs became trolleybus-operated, and this date thereby brought the return of trolleybuses to the Tavernelle route after an absence of around 32 years, now as route 1/4. The
voltage of the
overhead wires was increased from 600 V to 750 V in 2012. The change had long been planned, and some or most of the vehicles had been modified to run on the higher voltage several years earlier, but modification of the substations was not completed until 2012. The fleet was renewed in 2012–14. Two new
Solaris Trollino trolleybusesthe system's first
articulated trolleybusesentered service on 18 February 2013, and the last example of the nine
Menarini trolleybuses that had provided the service since the 1980s was withdrawn in March 2013. ==Services==
