the overhead wires, however, were left intact, so as to allow for a possible future decision to reopen the system. by 1985, it had been tentatively decided that trolleybus service in bologna should be revived, with a new fleet of vehicles. in 1988, orders were placed for a fleet of 20 new trolleybuses: 10 from menarini and 10 from breda. it was decided that the first line of the reactivated system would be line 13, which was a union of the old lines 41 and 46, with some changes in the city centre portions to connect the two — in particular, new wiring along via san felice, via rizzoli, via santo stefano and other streets for eastbound trolleybuses. line 13 would now be a cross-city radial line from borgo panigale to san ruffillo via the city centre. the long-disused overhead wires along former routes 41 and 46 were refurbished in preparation for a planned 1990 reopening. by spring 1990, delivery of both types of new trolleybuses had begun. a ceremonial "inauguration" event took place on 20 april 1990, in connection with a transport conference being held, with one trolleybus of each type running over a short section of the route that was temporarily energised for the occasion.
