ITALIAN RAIL LINE BUILT OVER, ON AND BELOW GROUND

The 173-mile high-speed line of the Italian State Railways between Rome and Florence involves construction of three major tunnels--6.8, 6.3 and 3.5 miles long. The two longer tunnels are being dug with U.S. tunneling machines. The initial 76-mile segment of this electrified line, which ultimately will have four tracks, is scheduled to open in the Spring of 1975. Meanwhile the nation's economic problems may force cancellation of rail construction projects other than the $2.5 billion Direttissima which is designed for trains to operate at 145 mph.
