A new six-mile section of Rome's slowly expanding subway system opened this month. An extension of Line B, it links the northeastern outskirts with the central railroad terminal (Stazione Termini), the hub of the Metropolitana subway network. The old section of Line B, opened in 1955, runs from the rail terminal to the Colosseum, the modern World's Fair quarter and the Cecchignola military barracks, with a branch from the Ostiense stop to the seaside at Ostia, 13 miles from the center. The 10-year-old Line A runs from the southeastern outskirts near the Alban Hills to the rail terminal and to Via Ottaviano, a 10-minute walk from St. Peter's Square. A westward extension is planned.

The new Line B section provides a link between the Tiburtina railroad station in the northeast and the central railroad terminal. It is welcomed by many rail passengers because some long-distance trains between northern and southern Italy, including Sicily, stop only at Tiburtina, where it is often hard to get a cab, but not at Stazione Termini. A ride on the Roman subways still costs 61 cents, but the fare will soon go up.

A major reason subway construction in Rome is being competed gingerly is the city's buried past. Wherever digging starts, fragments of ancient statuary, remains of pagan temples and other finds come to light, and contractors have to suspend work until the archeologists are satisfied.


Daily nonstop flights between Newark and Ponce, P.R., are to be introduced by Eastern Airlines on Thursday, giving travelers a second major gateway to Puerto Rico and the opportunity to bypass the San Juan airport. The service to Ponce, the port city on the Caribbean on the island's southern coast, is the first from the mainland. The airport has been expanded to accommodate wide-bodied aircraft such as the Boeing 757 that Eastern will use on the route. The flights are scheduled to leave Newark daily at 7:15 a.m., arriving in Ponce at 11:45 a.m. Return flights leave Ponce at 12:50 p.m. and arrive in Newark at 3:40 p.m. Eastern said fares would be from $248 round trip in coach.
