Rome. In the historic centre of the Eternal City mechanical moles are excavating the tunnels of the third subway line. The most important problem the engineers must face is how to guarantee passenger safety. For this purpose, Roma Metropolitane arranged a comprehensive fire test. A modern train- carriage was exposed to fire-tests within a 100 -meter purpose-built gallery, monitored by an elaborate system of sensors, 7 video-cameras and 2 thermo-cameras. Two documentaries propose to show the results of this test.
