the Crocetta overpass (on which it was planned to install the overhead wire to extend the line). Then, on 24 July 1965, the line was diverted to the new hospital (Policlinico). The line along la Crocetta was abandoned, and later permanently deleted (on 18 June 1966) and replaced by the new line 7, routed via Largo Porta Sant'Agostino to Modena railway station, and following the new routing at Viale Monte Kosica. Also, line 4 to Madonnina was abandoned. On 2 October 1967, an extension of line 6 was inaugurated from Viale Buon Pastore to Via Conco, including a level crossing over the SEFTA line to Sassuolo. This extension was constructed from scratch. The following years saw only contraction of Modena's trolleybus system. The closure in 1964 of the railway to Mirandola, and the planned closure (implemented in 1969) of the railway to Vignola, reduced the importance of Modena's "little station" (Modena Piazza Manzoni railway station), and trolleybus lines 1 and 2. Both lines were therefore closed on 21 August 1968, together with line 3, which was transformed into a conventional bus line and extended. Finally, on 2 October 1972, under the pretext of converting Viale Fabrizi to one-way traffic, line 5 was closed. Austerity The long sequence of closures was stopped, at least in part, by the so-called austerity, and the concomitant spread of ecological awareness. Indeed, the scarcity of fuel available for private traffic had necessitated increased frequency of public transport. However, to avoid excessively intensive bus traffic in the streets of Old Town, it was decided to divert the conventional buses onto the ring roads. This left only the trolleybuses in the city centre, to operate the two north-south and east-west bus lines, the high frequency lines. Limited availability of trolleybuses enabled the continued operation of the important line 7, but forced the closure of line 6. The reform came into force on 1 October 1973. Less than a year later, on 15 June 1974, a further change took place, transforming line 7 and extending the EO shuttle bus service to the railway station. At the end of the period of austerity, after the need to ensure high frequencies, the EW and NS shuttles could be deleted, and lines 6 and 7 reactivated. The line 6 trolleybus assumed the designation 6-barrato (abbreviated as "6/"), being the reinforcement of a longer, conventional bus route. The network was then stable
