A book of stories written by passengers on Rome's public transport system has been published under the title "Parole in corsa". The 173 tales were selected from more than 300 sent to the Trambus web site (www.trambus.com) in response to an appeal for travellers to help construct a collective identity for users of the city's buses, trains, trams and metro. Each of the stories is short enough to be read during the course of a single journey on public transport, and they cover themes ranging from loneliness and escape to immigration and the history of Rome. "Parole in corsa" is on sale at Mondadori in Via Piave, priced at 10.
