Increased service on Metro B coincides with closure of Metro B1.

Rome is to increase the frequency of subway trains serving the Metro B between Laurentina and Rebibbia to cope with the large crowds expected for the Ryder Cup, the city said on Monday.

Metro B trains will run every five minutes from 28 September until 1 October, said the city's transport councillor Eugenio Patanè who noted that some 270,000 spectators are expected in Rome for the major golfing event.

Coinciding with the extra trains serving the Metro B line, the city will shut down the Metro B1 line, an offshoot of Metro B, serving four stations from Piazza Bologna to Jonio.

The reason for the closure of the B1 line, on the exact same days as Metro B will have extra trains, is to carry out "urgent checks and maintenance" on lighting systems and overhead lines, the city said in a statement.

The four Metro B1 stations affected by the closure will be served by shuttle buses from 28 September to 1 October.
