Good article about the light rail system - specifically opposition to it - in Corriere Della Sera:
"But with work on Line 1 under way, and about to commence on the other two lines, a gaggle of citizens’ committees supported by part of the radical Left and Centre-right has appeared to protest at the cutting down of trees, the high costs and the many inconveniences to residents, as well as the most serious charge of all: the violence to the city’s artistic heritage alleged to be caused by the light rail passing close to the Baptistery, a stone’s throw from the Cathedral. The upshot is a consultative referendum, scheduled for 17 February, which has split the city and could halt work."
