Construction of Artificial Castello and Moro Tunnel in protection of the Bologna - Lecce Railway in the section between km 370+101 and 371+096

Due to the war, the Pescara - Termoli  Railway Line section had been heavily damaged.
Reconstruction of the Castello tunnel included 136m of artificial single track tunnel. The wider section included the widening to double track of  the Moro Tunnel and the Moro bridge. Widening of the tunnel was done through envelopment of the existing tunnel without stopping normal operation. The tunnels stretched from the Tollo Canosa Sannita Station to the Ortona Station.
