after a delay of several years, caused in part by a shortage of trolleybuses, a limited use of trolleybuses in service on line 14 finally began on 24 september 2012. trolleybuses operate on the route on weekdays only, and most scheduled journeys continue to be operated by buses, until additional trolleybuses are acquired. the b and c branches are not equipped with wiring. at the time of opening for trolleybuses, the a branch was also not yet equipped with wiring along its outermost section, from rotonda paradisi to via due madonne, but construction work was under way. at due madonne terminus, trolleybuses and buses on line 14a eventually will turn around at a new roundabout at the intersection with via malvezza. however, initially they are entering the atc bus depot to turn around, pending completion of construction.
