On mai 23, 2009 the City of Turin welcomed the citizens to see the mole Caterina that successfully reached the future Carducci station, on its way to Lingotto.
Caterina is one of the TBM (Tunnel Boring Machines; the others are Valentina, Madama Cristina and Valeria) that have been excavating the tunnels at 20 mt underground for the Turin Metro's Line 1.
The mole is about 8 m. in diameter, its weight is 400 t. (TBM+cart) and it advances about 10 m. a day.
Capital as well as cultural and business center of the Piedmont region, Turin is famous as headquarters of Fiat and Lancia, birthplace of Telecom Italia and Rai television and host of the 2006 Winter Olympics. Turin has a modern public transport infrastructure so it is easy to get to architectural sites and museums, most notably the Mole Antonelliana, which is the home of the National Cinema Museum. Home to Torino and Juventus, two historical italian football teams, the region is famous as the birth place of solid chocolate over 200 years ago. Gianduiotto is perhaps the most famous Turin chocolate currently in production.
